Heating Oil FAQ (and not so FAQ)

heating-oil-tank

When it gets cold in the Pacific Northwest, it’s time to take a look at some common questions we have been asked about Heating Oil.  If you don’t see an answer to a question you have, please feel free to call, email, or message Star Oilco and we will gladly answer. We especially welcome questions  that require research.

What is Heating Oil in Oregon?

Heating Oil in Oregon is diesel and can have a biodiesel blend as well.  Diesel fuel has several grades either #1 or #2 Diesel.  The number refers to the grade with #1 being called either “stove oil” or “Kerosene” as another term for it.  Typically when someone is requesting or talking about heating oil they are talking about #2 Diesel dyed red to denote there are no on-road fuel taxes associated with the fuel.

There are several types of oil furnaces.  The most common is a vaporizing burner.  These furnaces typically work by taking a liquid combustible fuel, vaporizing it into a fine mist through a fuel oil nozzle, and igniting that mist into fire. That fire heats either air or water for your home’s comfort.

Air furnaces usually move the air through a heat exchanger where a blower then moves air over the heat generated by your furnace, and finally the air is pushed through your home’s vents. 

Boilers and Water furnaces heat a tank of water which is then distributed several different ways to heat your home.  Either by moving hot water to radiators, radiant plumbing under your floor, or to a heat exchanger and blower which transfers the heat from the hot water into vents blown throughout your home. 

The parts leading up to the Burner of of an oil furnace system are simple. There is a tank to hold a reservoir of oil, a line from that tank (and sometimes a line back to it), a fuel filter, a fuel pump, and a vaporizing burner that combusts the heating oil into fire. Combustion of the fuel takes place in a fire box next to the heat exchanger. The heat exchanger takes on the heat of the flames to heat either air or water. In an oil furnace, the heat exchanger is assisted with a blower that pushes the hot air throughout your home to keep you comfy.

If you have an above or below ground heating oil tank you can confirm your fuel volume by the inches of fuel in the tank.  If you have an above ground tank there is probably a tank gauge that can tell you an approximate volume in the tank.  If you have an below ground tank you can confirm how many gallons are in the tank by putting  a measuring stick or tape-measure into the tank.

You will want to confirm the size of the tank you have. Your oil provider will probably have an idea of what size your tank is by looking or historic deliveries. Star Oilco has a tank chart which will help.  If you place a stick or tape measure into your tank and see how much fuel is in it you can compare that to a tank chart found on Star Oilco’s website.  When delivering fuel you can “stick” measure the tank before and after the delivery. Compare these volumes with the delivery and you can often figure out your tank size based on the before and after volume lining up with how much fuel filled your tank.

Home heating oil can be either a petroleum diesel fuel, bio-synthetic diesel fuel, or biodiesel fuel. In Oregon and Washington, home heating oil is typically ultra-low sulfur diesel fuel often containing between 5% and 20% biodiesel. Star Oilco’s standard home heating oil fuel is B5 dyed ultra-low sulfur diesel. Oregon mandates require that all diesel fuel sold contain a minimum 5% biodiesel. For that reason Star Oilco carries B5 or 5% biodiesel blends in our heating oil.

(NOTE: Kerosene sold by Star Oilco contains no biodiesel due to the reality that wick heaters cannot handle even a minute amount of biodiesel in them.) Star Oilco also carries a 20% biodiesel blend, called B20 Bioheat, for customers who want a cleaner burning low carbon fuel for their home.

Kerosene is a heating oil product that is capable of being picked up and fed consistently by a wick heater. Kerosene is a diesel product that is very similar to the fuel used for over the road trucks. The big difference is that kerosene is a “lighter end” distillate fuel, which means it has a lighter specific gravity. This lighter characteristic means that it also works better in certain systems like wick heaters, pressure washers, and pot burner stoves.

It depends on what type of system the kerosene heater is operating with. If you have a wick heater it will not work with heating oil. You will likely have to replace the wick to get it to work again as diesel will not readily drawn into the wick. Even if it does, it will burn far dirtier. If it is a pot burning system like a Toyostove or Monitor heater, then it will burn ultra low sulfur heating oil. Increased maintenance is to be expected on the pot burner, as there is a likelihood of more coking (crusty black soot build up) to occur inside that system.

Bio heating oil and bioheat refer to heating oil products with a blend of biodiesel in them. Typically bioheat is a blend between 5% to 20% biodiesel with ultra low sulfur diesel for a clean burning and low CO2 heating fuel.

For a really in-depth look at biodiesel used as a heating oil check out this article. 

Yes, heating oil will run in a diesel engine. Heating oil is diesel. Be aware though that on-road vehicles must only run clear diesel fuels. If caught using heating oil in an on-road vehicle in Oregon and Washington, the fines can run in the tens of thousands of dollars. Heating oil can also be dyed to signify it isn’t for on-road use. 

Also be aware that even many off-road pieces of equipment and generators need ultra low sulfur diesel to operate without very expensive maintenance. Heating oil can have low sulfur or even high sulfur contents that could cause real issues for modern clean diesel engines. Some consideration is needed prior to burning a fuel marked “heating oil” in a diesel engine.

Consult your furnace, stove, boiler or water heater’s factory recommended specification. Typically it’s Number 2 Diesel unless it is a stove pot or wick heated system. If you have a furnace or a boiler in your basement, you can assume it’s heating oil. Call a licensed and bonded heating oil furnace technician to tune up your furnace to confirm for sure. If you do not have one, Star Oilco can refer you to a number of reputable long-time firms who can help.

Heating oil additives are added to fuel in order to improve it’s long term storage and performance.  They are worth it and most reputable heating oil providers additize their fuel without an extra charge.  This is because most heating oil customers store their fuel for long periods of time.  If you are planning on storing heating oil for years you will need a fuel additive to keep that fuel in the quality needed for your furnace.

Star Oilco provides a premium diesel additive called Hydrotex PowerKleen to every gallon of heating oil we sell.  Beyond this stabilizers, if you are planning on storing fuel for years we recommend ValvTect Plus 6.  You will want to treat your fuel with a biocide like ValvTect Plus 6 to will kill any bacteria, yeast, algae, or other biological organism that can grow inside your heating oil tank.

For more on storing diesel or heating oil for long periods of time please read this article on long term fuel storage.

Heating oil smells like diesel. It is a diesel product and often, depending on location, it is the same as on-road diesel. It may be dyed to denote that it is an off-road fuel with a untaxed use. Heating oil is dyed red in the Pacific NW to show it is off-road diesel.

Heating Oil #2 is number 2 diesel or the standard diesel sold in most places for on-road diesel use. Heating Oil #2 is a slightly different specification than on-road diesel that allows for more sulfur. That is a big difference as far as the EPA is concerned. On-road and off-road vehicles in the U.S. are required to use ultra-low sulfur diesel. Heating oil systems can use low or high sulfur diesel fuels. Ultra low-sulfur diesel is the most common Heating Oil #2 fuel that is delivered by Star Oilco since it is a superior and cleaner burning fuel, in our opinion.

In the Pacific NW heating oil is ultra low sulfur diesel. Therefore, you can buy any diesel sold at a retail gas station, truckstop, farm supply or other liquid fuel seller.  Heating oil is dyed red to show that it is not taxed for on-road fuel use.  Other than that red dye, typical auto-diesel will work in your oil furnace if you need to supply it from a diesel can.

Heating Oil Gel Point:

In the Pacific NW we expect number 2 diesel heating oils to be operable beyond -10 degrees. The record cold weather in the Willamette Valley is above 0 degrees (recent decades 16 degrees was our record low in Portland). We do test and add additives to our fuels to ensure they meet this specification even if they contain 5% biodiesel blended into heating oil.

Kerosene Gel Point:

Kerosene fuels (Number 1 Diesel, Number 1 Stove Oil, and Kerosene labeled fuels) are expected to be good below -30 degrees and are designed to be used in high altitude applications. (Kerosene and jet fuels are often the same specification in the Pacific NW.)

B20+ Biodiesel Gel Point:

Biodiesel blends of B20 and above are assumed to be good to 20 degrees but if Star Oilco expects below-freezing weather, we highly recommend B5 as your delivered fuel. B99 biodiesel typically gels at 40 degrees, so it’s not a winter fuel unless you have a system designed to keep the fuel warm in the middle of winter.

“Oil Heat” or “Oil Fired” refers to a heating system reliant on burning heating oil. Typically this is by use of a vaporizing burner that takes the combustible liquid that is heating oil and vaporizes it through a nozzle into an igniter that causes it to burn.  This system burns the heating oil, creating a great deal of heat that can warm air, water, or both to heat a home or commercial space.

NOTE: IF HEATING OIL HAS BEEN INGESTED PLEASE SEE A MEDICAL PROFESSIONAL.

Heating oil by itself is not dangerous or toxic if it come in contact with your skin.  It is easily washed off with soap and water.  A small amount of diesel spilled on the surface of the ground, typically will break down on it’s own in the presence of the environment.  A small amount spilled on concrete or asphalt can be cleaned up easily with dish soap and water. If your tank leaks and heating oil is soaked below ground this will not break down easily and will take professional help to treat.

The exhaust from heating oil systems contains carbon monoxide and carbon dioxide as well as particulates.  Heating oil and other diesel exhausts are very dangerous and toxic and should be avoided.  Do not allow exhausts of any kind to collect in an enclosed space.

Heating Oil’s vapor point (the temperature it turns to vapor and evaporates) is around 140 degrees Fahrenheit.  Heating oil ignites at 160 degrees.  Typically in the Pacific NW the temperature (especially outside) is well below the vapor and flash point of diesel fuels including heating oil and kerosene. If spilled it will not usually evaporate. You can clean heating oil and diesel up with regular dish soap and water.

Heating oil ignites at 160 degrees.  So unless the temperature is that high an explosion is not a risk.  Fire Code regulating heating oil tanks and placement takes this concern into account.  So typically except in extreme scenarios heating oil vapor does not pose an explosion risk.

If you drop a match into a cup of heating oil at room temperature it will go out.  If you hold a match to the surface of the heating oil in that cup the flame will get large and bright but the heating oil itself will not ignite.  Heating oil needs to be vaporized before it will ignite. It is a combustible fuel so it must be in a vapor form to light.  The vaporizing nozzle of your heating oil furnace turns diesel into a vapor mist easily ignitable.

Yes, heating oil can go bad. If you are planning to store heating oil for longer than a year, you should use a diesel additive that stabilizes fuel for long term storage. If you are storing the fuel as a back-up where you might go years without using it, you should also consider adding a biocide to ensure nothing grows in your tank. The two biggest threats to your fuel staying in specification are water and biological growth. Biological growth occurs inside the water that can collect in your tank bottom naturally through condensation over time.

Star Oilco treats 100% of our dyed fuels with Hydrotex Powerkleen to ensure that it is stable for storage for over a year. If you need to store it longer than that, we further recommend adding a desiccant breather to scrub moisture out of the air when your tank breaths, which protects it from additional water.

For more on additizing your heating oil for long term storage please follow THIS link.

Yes, heating oil tanks properly installed outside are perfectly safe and capable of ensuring your fuel stays clean and dry.

Yes, at several different levels. With residential use, there are local jurisdictions’ building permit requirements for installation and safety. With commercial use, there is the same building permit regulation and usually an added level of Fire Marshall sign-off for siting of any tanks. In rural areas, regulations are different if the tank is associated with an agricultural use.

In Oregon and Washington, a 90 day temporary tank for construction purposes (to move from one tank to another in a formal process) is usually allowed, but you should ensure the temporary tank is a double wall tank and is in a safe place. If your tank leaks (or even if there is a suspicion of a leak), the Oregon Department of Environmental Quality and Washington Department of Ecology have an involved process to close out a leaking oil tank.  

Yes, you need to ensure you maintain your oil furnace. Star Oilco recommends getting a tune up annually or at least every other year.  If you are seeking a referral to a HVAC company that specializes in oil heat, call Star Oilco’s office 503-283-1256 and ask for a list of qualified license and bonded companies we recommend. You also want to check your oil furnace for water annually. Star Oilco can stick your tank for water at no charge upon request with a fuel delivery.

One of the great benefits of oil heat is that oil furnaces are known to last for over fifty years if maintained properly. Natural gas and propane furnaces typically wear out every ten to twenty years dependent on their construction. The primary wear consideration on any furnace is the heat exchanger. The heavy steel part takes the flame of burning fuel, transmits this heat to the air, and is then pushed to heat your home. Oil furnaces must be tuned up every year or two to ensure the heat exchanger is cleaned.

If you do not service the heat exchanger, it will collect soot. Soot insulates the heat exchanger unevenly and causes wear that will eventually lead to a crack. If a heat exchanger is cracked, the furnace is no longer safe to operate. Additionally, an annual tune-up will pay for itself by ensuring your furnace is burning at peak efficiency. You will want to replace your furnace air filter regularly on an annual basis.

Tuning your furnace annually or every other year is highly recommended. Adjusting the fuel air mixture for the most efficient combustion goes a long way to ensure you use as little heating oil as possible. Star Oilco has witnessed fifty and even seventy year oil furnaces operate at modern efficiencies when maintained regularly over their lives. Today, there are a host of high efficiency oil furnaces manufactured and supported to reduce your cost of fuel.  Additionally, confirming the envelope of your home is not drafty or needlessly wasting heat can go a long way in reducing your heating expenses.

The price of heating oil fluctuates frequently due to market conditions. Comparison shopping is your best way to ensure you pay the best possible price. One web based tool we have heard customers like to use to save time while shopping for heating oil is Fuelwonk.com.  It is free and easy to use.

Even though the cost of fuel is dependent on the market and out of our control, there are best practices to reduce the amount of oil you’ll need. The temperature you keep your house will affect how much oil you go through. Keeping your temperature higher will lead to more oil burned during the winter months. How insulated your home is will also affect the amount of oil you burn. Having poor insulation will result in having your furnace running hotter for longer periods of time, increasing fuel use. Annual maintenance of your furnace will keep your furnace operating at top efficiencies. Having a well working and operating furnace will keep costs down by not wasting oil on an underperforming unit.

Star Oilco also has a number of discounts and programs for price reduction. We offer $.05/gallon veteran and senior citizen discount. We frequently have discounts on Google and our social media pages so make sure to check those out. Mention where you saw it to receive the discount.

Heating oil customers at Star Oilco have the opportunity to enroll in our Equal Pay program. The program allows you to make equal monthly payments on future heating oil deliveries. As an Equal Pay customer, you will receive a discount of .20 cents per gallon on all heating oil deliveries. We also have an Autofill program which dictates you receive our best price as well as automatic deliveries. You don’t have to keep track of your fuel or when you need a delivery. We do the work for you!

If you do not like our price and someone else is cheaper let us know.  We will match their price.

Heating Oil is a modern fuel that uses today’s heating oils and biofuels.  The investments in research and development for heating oil furnace by the National Oil Research Alliance to use a wider variety of biofuels in higher lower CO2 blends have kept heating oil relevant in many applications.  As a heating fuel, it’s use will become more rural than urban rather than a phase out. As it is today, the use of heating oil will be used where natural gas is not available especially if the temperatures get below zero. Urban adoption of natural gas has increased, as it’s cheaper than heating oil due to increased fracking development of petroleum.

Star Oilco uses a Degree Day system for our customers on Automatic Keep-Full Service.  We fill your tank before it needs it automatically. A statistical regression analysis correlates your typical use of heating oil in your home and the weather.  Our systems will track your usual fuel usage and we automatically schedule delivery to keep your tank full.

The technical term “BTUs” refers to “British Thermal Units” which is a measure of energy content of a fuel. The energy content of diesel fuels can vary slightly by regions and specifications of those regions.  In the Pacific Northwest, heating oil is typically Ultra Low Sulfur Diesel with a blend of biodiesel content. This can range from 5% to 20% biodiesel added to the fuel. This means the exact BTU measured for a gallon of heating oil an slightly vary.

Source: US Alternative Fuel Data Center Fuel Properties Comparisons
Ultra Low Sulfur Diesel: 128,488 BTUs to 138,490 BTUs per gallon.
B5 Biodiesel is presumed to be about the same BTUs as ULS Diesel.
B100 Biodiesel: 119,550 BTUs to 127,960 BTUs per gallon.
B20 Biodiesel: 126,700 BTUs to 136,384 BTUs per gallon.

Maintenance tips for a longer-lasting heating oil tank 

To extend the lifespan of your heating oil tank, proactive maintenance is key. Here are some essential tips to keep in mind: 

Regular inspections:  

In order to ensure that your tank is in good working order, you should have an annual inspection performed by a certified professional who can assess the tank’s condition, check for corrosion, and ensure that all of the components are functioning properly. The professional should also check for leaks, inspect the tank’s piping, and ensure that it is properly sealed. They should also test the safety equipment and make any necessary changes. They should provide a report with their findings and recommendations. 

Monitor oil levels:

Regularly check the oil level in your tank and schedule heating oil refills to prevent the tank from running dry. As a result of an empty tank, sludge and sediment will build up, accelerating corrosion as time goes by. This can shorten the lifespan of the tank, resulting in costly repairs and replacements. Additionally, an oil leak can cause environmental damage and contaminate groundwater.

Keep the area clean:

If there is any debris, vegetation, or objects around the heating oil tank that could trap moisture or cause it to rust, it must be removed. The tank should be properly ventilated, and it should be accessible to inspection and maintenance so that the tank can be inspected.

Check for leaks:

Ensure that your heating oil tank is routinely inspected for any signs of leaks, such as stains, odors, or an unusually high rate of oil consumption. As soon as you find a leak, take immediate action to prevent environmental contamination and property damage.  Contact the professionals as soon as possible to arrange for repairs. Clean out any spilled oil with the proper equipment. Document the accident and report it to your local authorities.

Install a tank protection system:

It may be a good idea to install a tank protection system, such as a tank tray or electronic leak detection system, in order to protect the tank. As a result of these devices, an additional layer of safety can be added, and leaks can be detected at an early stage in advance.  This can help to avoid unnecessary environmental damage, as well as costly repairs. Additionally, it can help to extend the life of the tank, as any potential issues can be addressed quickly.

Monitor water accumulation:

It is possible for water to accumulate in your heating oil tank due to condensation, which speeds up the corrosion process. It is important to keep an eye out for water accumulation and to consider the installation of an absorbent pad or a water drain to mitigate the problem.

Saving money on heating oil can help reduce costs during the cold season.

Here are some ways to save money on heating oil this season: 

Turn down your thermostat.

Typically your bill will be reduced by one to three percent every degree you lower the thermostat. You could save up to 12 percent on your heating costs by setting your thermostat to 68 degrees Fahrenheit instead of 72.

Use a programmable thermostat.

It is possible to set your thermostat to different temperatures at different times of the day with a programmable thermostat. You could, for instance, set it to turn down the heat while you sleep or are away from home. 

lower-thermostat-saving-money-on-heating-oil

Seal drafts.

If there are drafts in your home, cold air can enter and make your home less energy-efficient. You should look for drafts around doors, windows, and other openings in your home. A door sweep, caulk, or weatherstripping can be utilized to seal drafts around doors and windows to saving money on your heating bill.

Insulate your home.

You can keep your home warm in the winter and cool in the summer by installing insulation in your home. The attic, the walls, and the basement of your home can all be insulated if it is not well insulated already.

Have your heating system tuned up.

You may be able to increase the efficiency of your heating system and reduce your heating costs by having a heating system tune-up performed. A professional tune-up will examine the system and look for any potential problems or inefficiencies. They will also be able to adjust any settings or adjust the thermostat to maximize heating oil efficiency. Having a professional tune-up can help ensure that your heating system is running as efficiently as possible.

save-money-on-heating-oil

Here are some additional tips for saving money on heating oil this year:

It is important to keep your fuel tank full as often as possible. The purpose of this is to avoid condensation from forming in the tank, which can then lead to corrosion and rust as a result. 

Radiator bleed keys can be used to remove air from radiators. As a result, your heating system will run more efficiently. Bleeding radiators also helps to prevent corrosion in the heating system. It also helps to prevent overheating. 

Make sure you clean your furnace filter on a regular basis. It is possible for a dirty filter to restrict airflow and make your system work harder as a result.

How Heating Oil Works 150 150 Star Oilco

How Heating Oil Works

During the colder months, heating oil is a widely used fuel source for residential heating systems. Understanding the processes of how heating oil works can help homeowners make informed decisions, ensure optimal equipment performance, and maximize energy efficiency. 

Production and Composition of Heating Oil:  

Heating oil is a petroleum-based product derived from crude oil. As with gasoline and diesel fuel, it is refined by removing impurities and separating it from other petroleum products. Generally heating oil consists of hydrocarbons, including long-chain alkanes and aromatic compounds although the specific composition of heating oil may vary slightly. 

Storage and Delivery:  

Above ground and underground tanks are typically how heating oil is stored, located on the property where it is needed. The oil is delivered by specialized trucks that transport it from refineries or storage facilities, pumping it from the truck into the storage tank. Tanks are equipped with various protective measures, such as overfill prevention devices and leak detection systems. 

View our heating oil tank chart here.

Combustion Process:

Heating oil operates in a similar manner to other fossil fuels when it comes to the combustion process. The oil is drawn from the storage tank to the burner in the heating system, where it mixes with air and is atomized into a fine spray. This mixture is then ignited by an electric spark or a pilot flame, generating heat that warms the air or water circulated throughout the house. 

Heating oil combustion occurs in a combustion chamber or a furnace. This is where the heat is transferred to a heat exchanger. Afterwards, the heat exchanger transfers heat to air or water, which is distributed throughout the house through ductwork or pipes. The byproducts of the combustion process, including carbon dioxide, water vapor, and small amounts of sulfur dioxide, are safely vented outside. 

How efficient are heating oil systems? 

The energy efficiency of a heating oil system varies depending on the efficiency of the burner and the overall system design. Heat can be most maximized by using high-efficiency burners and making sure equipment has been well-maintained to minimize fuel consumption and reduce emissions. 

Over the years, there have been significant advancements in heating oil technology to enhance the overall performance. Ultra-low sulfur heating oil (ULSHO) has become more common, with sulfur content reduced to less than 15 parts per million (ppm). This significantly reduces sulfur dioxide emissions. Biodiesel blends, made from renewable sources such as soybean oil or recycled cooking oil, can also be mixed with heating oil to further reduce carbon emissions. 

cozy-house-heating-oil-keep-warm-efficient

Heating oil plays a crucial role in keeping our neighbors in Portland, Oregon warm and comfortable during the winter months. Understanding the production process, storage and delivery methods, combustion process, and environmental considerations associated with heating oil can help homeowners make educated and informed decisions, ensuring they have an efficient operation with their equipment, and they can even contribute to a greener future.

What is Heating Oil? 150 150 Star Oilco

What is Heating Oil?

In the Pacific Northwest heating oil is diesel.

Star Po;cp Crest

New heating oil customers often ask us, “What is heating oil?” Heating oil is diesel fuel and there are several grades and types. For Star Oilco our standard heating oil product is a ultra low sulfur diesel with a 5% biodiesel blend in order to meet Oregon mandates for off-road diesel fuel. That way our heating oil trucks can also serve construction fueling, emergency back up generators, and other common off-road diesel uses.

Star Oilco has a simple Heating Oil FAQ available.

For full on fuel nerds though, check out this more in depth deeper technical dive below.  If we leave anything out please don’t hesitate to ask for those seeking a nerd-level understanding of heating oil, kerosene and bioheat.

There are three typically grades of heating oil you can order.

Number 1 Diesel

Number 1 diesel is also called Kerosene or Stove Oil. This fuel has a lighter specification than typical heating oil which enables it to burn better in a “pot burner” or wick heater. Kerosene has its own specification as the fuel used by wick heaters. Kerosene is typically Number 1 diesel but not all Number 1 diesel’s are kerosene due to the need to be taken up by a wick heater. Any biodiesel content in a kerosene product WILL NOT work in a wick kerosene heater. So be very aware of confirming that your kerosene has never come into any contact with a biodiesel blend of fuel.

Red Number 2 Diesel

Red dyed diesel also called Heating Oil, Dyed Diesel, Off-Road Diesel is the default heating oil fuel. The fuel is dyed red to denote no on-road fuel taxes are attached to it. When you call and ask for heating oil, this is the fuel you are requesting. Clear or Green Number 2 Diesel is the fuel sold at retail gas stations and truck stops. That fuel will also work in your furnace, you just are paying for on-road taxes attached to that fuel.

Bioheat or Biodiesel Heating Oil

“Bioheat” is a blend of biodiesel and petroleum diesel to make a lower emission and lower CO2 heating fuel.  Typically Bioheat is Number 2 Heating Oil with a 20% blend of biodiesel or higher in it. It is a drop-in fuel for your heating oil furnace. There is no change other than routine maintenance is required. It is a cleaner burning fuel with a significant drop in CO2 emissions associated with your heating oil fuel consumption.  If you would like more information on biodiesel as a heating oil you can follow this link.

B20 Biodiesel Heating oil provider

Where do heating oil companies get their fuel?

In the Portland, Oregon market, diesel is fungible. Everyone buys or is expected to mix their fuel from each other in some way. Primarily this is due to the Portland/Vancouver market receiving most of its fuel down the Kinder Morgan-operated Olympic Pipeline. Which means all the refiners transporting fuel are mixing their product in transit. Additionally, there are shared terminal locations, which also have co-mingled owned diesel products.

Every refiner is typically expecting to mix their diesel and gasoline products. The difference is in the care a vendor takes to filter the fuel, using additives and continuously check their fuel quality. If you are buying at the absolute lowest price possible, know that there is an incentive to skip any added value of quality assurance.

Star Oilco buys our diesel products from a variety of vendors. The source refiner typically being either BP, Shell, Marathon(formerly Tesoro), Phillip 66, or a number of other refiners.

Portland, Oregon and Vancouver, Washington are not unique in in having fungible diesel and heating oil fuel specifications. Through its Pacific Operations unit, Kinder Morgan operates approximately 3,000 miles of refined products pipeline that serves Arizona, California, Nevada, New Mexico, Oregon, Washington and Texas. With roots dating back to 1956, it is the largest products pipeline in the Western U.S., transporting more than one million barrels per day of gasoline, jet fuel and diesel fuel to our customers. The company-owned terminals also provide additional services, such as liquid petroleum product storage and loading facilities for delivery trucks.

The heating oil and biofuel blends Star Oilco sells its customers

Heating oil is essentially off-road diesel. You can legally use a higher sulfur content for boilers and heating systems than you can off-road equipment and back-up generators. Regardless, we sell the lowest sulfur fuel available and optimize our fuel to be as versatile to our customers as possible. Construction equipment, back up generators and a host of others systems use off-road diesel, as do heating oil systems. Star Oilco sells the same diesel fuel specification for all of our off-road uses.

We also blend this fuel with biodiesel for our customers that want higher blends of low CO2 biodiesel fuels and heating oil. Star Oilco carries nothing but ultra low sulfur diesel fuels. In fact, our minimum blend of biodiesel is a B5 biodiesel blend (5% biodiesel and 95% petroleum diesel) and we also offer B20 (20% biodiesel blend) and B99 (99% pure biodiesel) for our customers.

About Diesel Fuels Specifications 

In the United States, diesel fuel is controlled according the American Society for Testing and Materials Standard D975-97. This standard describes a limited number of properties that diesel fuels must meet. It should be noted that the requirements are all performance-based, meaning they do not mandate the composition of the fuel, only the specific performance related requirements demanded of a fuel for a diesel engine. The requirements of D975 are described below.

ASTM Specifications for Diesel Fuel Oils (D975)*

*More info on ASTM specifications

Diesel fuel is characterized in the United States by the ASTM standard D975, which identifies five grades of diesel fuel. We are only going to talk about the two most popular commercially diesel fuel used — No 1 and No. 2 diesel. The ASTM D975 standard is made up of a series of different tests that check the characteristic ranges of a fuel to confirm it is adequate to operate in your equipment.

In simple terms, they are checking for specific gravity, the vapor point (when it turns into a gas), the flash point (when it catches fire), the dirt content, water content (how much microscopic entrained water) and a host of other requirements diesel must meet in order to be legal to be sold for use in your engine.

Grade No. 1-D and Ultra-Low Sulfur 1-D:

This is a light distillate fuel for applications requiring a higher volatility fuel to accommodate rapidly fluctuating loads and speeds, as in light trucks and buses. The specification for this grade of diesel fuel overlaps with kerosene and jet fuel, and all three are commonly produced from the same base stock. One major use for No. 1-D diesel fuel is to blend with No. 2-D during winter to provide improved cold flow properties. Ultra-low sulfur fuel is required for on-highway use with sulfur level < 0.05%. 

Grade No. 2-D and Ultra-Low Sulfur 2-D:

This is a middle- or mid-grade distillate fuel for applications that do not require a high volatility fuel. Typical applications include high-speed engines that operate for sustained periods at high load. Ultra-low sulfur fuel is required for on-highway use with sulfur level < 0.05%.

Biodiesel Fuels for Heating Oil

Biodiesel is a renewable fuel produced from oil seed crops, used cooking oil, and/or animal fat waste. It is chemically similar to petroleum diesel, and is produced by combining the oil stock with catalysts and then heating it. Biodiesel is not the same as vegetable oil or SVO (straight vegetable oil) and can be used in any diesel engine.

Biodiesel and biodiesel blends significantly reduce tailpipe emissions, especially carbon dioxide, carbon monoxide, sulfur dioxide and particulates (black smoke). ASTM D975 standard, as of 2008, allowed up to 5 percent biodiesel to be blended into the fuel. This is the called B5 — the ‘B’ stands for biodiesel and 5 stands for up to 5 percent biodiesel.

B6 to B20 – ASTM D7467-17:

Diesel blends up to 20% and more than 6% are referred to as B20. Biodiesel is a cleaner burning fuel than petroleum diesel. Using biodiesel can help reduce the amount of harmful emissions released into the air. Emissions such as sulfur dioxide, carbon monoxide, polycyclic aromatic hydrocarbons and other compounds found in diesel exhaust. Read the ASTM D7467-17 standards.

B99 & B100 –  ASTM D6751-15ce1:

These are fuels made of up to 100% biodiesel. Due to environmental regulations, most retailers will carry a maximum of B99. The standards for B99 and B100 are identical. Unlike gasoline, biodiesel can gel at cold temperatures. This can cause stress on fuel pumps and fuel injection systems, or can clog filters or even become too thick to pump to the engine. B99 has a higher temperature gel rate – meaning that it begins to cloud and thicken at higher temperatures – than conventional diesel.

“The cloud point of soybean biodiesel is about 34°F (1°C), whereas the cloud point for No. 1 diesel is about – 40°F (-40°C) and for No. 2 diesel between -18°F (-28°C) and +20°F (-7°C).” (Biodiesel Cloud Point and Cold Weather Issues) The solutions for cold weather involve additives and lower blends to ensure continuous operations. Read the ASTM D6751-15ce1 standards.

Heating Oil FAQ (and not so FAQ)

Every Question Star Oilco has been asked about Heating Oil

It’s getting cold again in the Pacific Northwest, so it is time to take a look at some common questions we have been asked about Heating Oil.  If you don’t see an answer to a question you have, please feel free to call, email, or message Star Oilco and we will gladly answer. We especially welcome questions  that require research.

What is Heating Oil in Oregon?

Heating Oil in Oregon is diesel and can have a biodiesel blend as well.  Diesel fuel has several grades either #1 or #2 Diesel.  The number refers to the grade with #1 being called either “stove oil” or “Kerosene” as another term for it.  Typically when someone is requesting or talking about heating oil they are talking about #2 Diesel dyed red to denote there are no on-road fuel taxes associated with the fuel.

How Does a Furnace Work?

There are several types of oil furnaces.  The most common is a vaporizing burner.  These furnaces typically work by taking a liquid combustible fuel, vaporizing it into a fine mist through a fuel oil nozzle, and igniting that mist into fire. That fire heats either air or water for your home’s comfort.

Heating Oil Fired Air Furnaces

Air furnaces usually move the air through a heat exchanger where a blower then moves air over the heat generated by your furnace, and finally the air is pushed through your home’s vents. 

Heating Oil Fired Water Furnaces and Boilers

Boilers and Water furnaces heat a tank of water which is then distributed several different ways to heat your home.  Either by moving hot water to radiators, radiant plumbing under your floor, or to a heat exchanger and blower which transfers the heat from the hot water into vents blown throughout your home. 

Heating Oil System prior to the combustion system

The parts leading up to the Burner of of an oil furnace system are simple. There is a tank to hold a reservoir of oil, a line from that tank (and sometimes a line back to it), a fuel filter, a fuel pump, and a vaporizing burner that combusts the heating oil into fire. Combustion of the fuel takes place in a fire box next to the heat exchanger. The heat exchanger takes on the heat of the flames to heat either air or water. In an oil furnace, the heat exchanger is assisted with a blower that pushes the hot air throughout your home to keep you comfy.

How Do I Check the Volume of Fuel in My Tank?

If you have an above or below ground heating oil tank you can confirm your fuel volume by the inches of fuel in the tank.  If you have an above ground tank there is probably a tank gauge that can tell you an approximate volume in the tank.  If you have an below ground tank you can confirm how many gallons are in the tank by putting  a measuring stick or tape-measure into the tank.

You will want to confirm the size of the tank you have. Your oil provider will probably have an idea of what size your tank is by looking or historic deliveries. Star Oilco has a tank chart which will help.  If you place a stick or tape measure into your tank and see how much fuel is in it you can compare that to a tank chart found on Star Oilco’s website.  When delivering fuel you can “stick” measure the tank before and after the delivery. Compare these volumes with the delivery and you can often figure out your tank size based on the before and after volume lining up with how much fuel filled your tank.

What is “Home Heating Oil” or “Residential Heating Oil?”

Home heating oil can be either a petroleum diesel fuel, bio-synthetic diesel fuel, or biodiesel fuel. In Oregon and Washington, home heating oil is typically ultra-low sulfur diesel fuel often containing between 5% and 20% biodiesel. Star Oilco’s standard home heating oil fuel is B5 dyed ultra-low sulfur diesel. Oregon mandates require that all diesel fuel sold contain a minimum 5% biodiesel. For that reason Star Oilco carries B5 or 5% biodiesel blends in our heating oil.

(NOTE: Kerosene sold by Star Oilco contains no biodiesel due to the reality that wick heaters cannot handle even a minute amount of biodiesel in them.) Star Oilco also carries a 20% biodiesel blend, called B20 Bioheat, for customers who want a cleaner burning low carbon fuel for their home.

What is Kerosene?

Kerosene is a heating oil product that is capable of being picked up and fed consistently by a wick heater. Kerosene is a diesel product that is very similar to the fuel used for over the road trucks. The big difference is that kerosene is a “lighter end” distillate fuel, which means it has a lighter specific gravity. This lighter characteristic means that it also works better in certain systems like wick heaters, pressure washers, and pot burner stoves.

Can Heating Oil be Used in a Kerosene Heater?

It depends on what type of system the kerosene heater is operating with. If you have a wick heater it will not work with heating oil. You will likely have to replace the wick to get it to work again as diesel will not readily drawn into the wick. Even if it does, it will burn far dirtier. If it is a pot burning system like a Toyostove or Monitor heater, then it will burn ultra low sulfur heating oil. Increased maintenance is to be expected on the pot burner, as there is a likelihood of more coking (crusty black soot build up) to occur inside that system.

What is “Bio Heating Oil” or Bioheat?

Bio heating oil and bioheat refer to heating oil products with a blend of biodiesel in them. Typically bioheat is a blend between 5% to 20% biodiesel with ultra low sulfur diesel for a clean burning and low CO2 heating fuel.

For a really in-depth look at biodiesel used as a heating oil check out this article. 

Will Heating Oil Run a Diesel Engine?

Yes, heating oil will run in a diesel engine. Heating oil is diesel. Be aware though that on-road vehicles must only run clear diesel fuels. If caught using heating oil in an on-road vehicle in Oregon and Washington, the fines can run in the tens of thousands of dollars. Heating oil can also be dyed to signify it isn’t for on-road use. 

Also be aware that even many off-road pieces of equipment and generators need ultra low sulfur diesel to operate without very expensive maintenance. Heating oil can have low sulfur or even high sulfur contents that could cause real issues for modern clean diesel engines. Some consideration is needed prior to burning a fuel marked “heating oil” in a diesel engine.

What Fuel Do I Need?

Consult your furnace, stove, boiler or water heater’s factory recommended specification. Typically it’s Number 2 Diesel unless it is a stove pot or wick heated system. If you have a furnace or a boiler in your basement, you can assume it’s heating oil. Call a licensed and bonded heating oil furnace technician to tune up your furnace to confirm for sure. If you do not have one, Star Oilco can refer you to a number of reputable long-time firms who can help.

What Are Additives and Are They Worth it?

Heating oil additives are added to fuel in order to improve it’s long term storage and performance.  They are worth it and most reputable heating oil providers additize their fuel without an extra charge.  This is because most heating oil customers store their fuel for long periods of time.  If you are planning on storing heating oil for years you will need a fuel additive to keep that fuel in the quality needed for your furnace.

Star Oilco provides a premium diesel additive called Hydrotex PowerKleen to every gallon of heating oil we sell.  Beyond this stabilizers, if you are planning on storing fuel for years we recommend ValvTect Plus 6.  You will want to treat your fuel with a biocide like ValvTect Plus 6 to will kill any bacteria, yeast, algae, or other biological organism that can grow inside your heating oil tank.

For more on storing diesel or heating oil for long periods of time please read this article on long term fuel storage.

What Does Heating Oil Smell Like?

Heating oil smells like diesel. It is a diesel product and often, depending on location, it is the same as on-road diesel. It may be dyed to denote that it is an off-road fuel with a untaxed use. Heating oil is dyed red in the Pacific NW to show it is off-road diesel.

What is Heating Oil #2?

Heating Oil #2 is number 2 diesel or the standard diesel sold in most places for on-road diesel use. Heating Oil #2 is a slightly different specification than on-road diesel that allows for more sulfur. That is a big difference as far as the EPA is concerned. On-road and off-road vehicles in the U.S. are required to use ultra-low sulfur diesel. Heating oil systems can use low or high sulfur diesel fuels. Ultra low-sulfur diesel is the most common Heating Oil #2 fuel that is delivered by Star Oilco since it is a superior and cleaner burning fuel, in our opinion.

Where can I buy heating oil at the pump?

In the Pacific NW heating oil is ultra low sulfur diesel. Therefore, you can buy any diesel sold at a retail gas station, truckstop, farm supply or other liquid fuel seller.  Heating oil is dyed red to show that it is not taxed for on-road fuel use.  Other than that red dye, typical auto-diesel will work in your oil furnace if you need to supply it from a diesel can.

At What Temperature Does Heating Oil Freeze?

Heating Oil Gel Point:

In the Pacific NW we expect number 2 diesel heating oils to be operable beyond -10 degrees. The record cold weather in the Willamette Valley is above 0 degrees (recent decades 16 degrees was our record low in Portland). We do test and add additives to our fuels to ensure they meet this specification even if they contain 5% biodiesel blended into heating oil.

Kerosene Gel Point:

Kerosene fuels (Number 1 Diesel, Number 1 Stove Oil, and Kerosene labeled fuels) are expected to be good below -30 degrees and are designed to be used in high altitude applications. (Kerosene and jet fuels are often the same specification in the Pacific NW.)

B20+ Biodiesel Gel Point:

Biodiesel blends of B20 and above are assumed to be good to 20 degrees but if Star Oilco expects below-freezing weather, we highly recommend B5 as your delivered fuel. B99 biodiesel typically gels at 40 degrees, so it’s not a winter fuel unless you have a system designed to keep the fuel warm in the middle of winter.

What do “Oil Heating,” “Oil Fired Heater,” or “Oil Furnace” Mean When Referring to a House?

“Oil Heat” or “Oil Fired” refers to a heating system reliant on burning heating oil. Typically this is by use of a vaporizing burner that takes the combustible liquid that is heating oil and vaporizes it through a nozzle into an igniter that causes it to burn.  This system burns the heating oil, creating a great deal of heat that can warm air, water, or both to heat a home or commercial space.

Can Heating Oil Fumes Make You Sick?  Are the Fumes Harmful, Dangerous, or Toxic?

NOTE: IF HEATING OIL HAS BEEN INGESTED PLEASE SEE A MEDICAL PROFESSIONAL!

Heating oil by itself is not dangerous or toxic if it come in contact with your skin.  It is easily washed off with soap and water.  A small amount of diesel spilled on the surface of the ground, typically will break down on it’s own in the presence of the environment.  A small amount spilled on concrete or asphalt can be cleaned up easily with dish soap and water. If your tank leaks and heating oil is soaked below ground this will not break down easily and will take professional help to treat.

The exhaust from heating oil systems contains carbon monoxide and carbon dioxide as well as particulates.  Heating oil and other diesel exhausts are very dangerous and toxic and should be avoided.  Do not allow exhausts of any kind to collect in an enclosed space.

Can Heating Oil Evaporate?

Heating Oil’s vapor point (the temperature it turns to vapor and evaporates) is around 140 degrees Fahrenheit.  Heating oil ignites at 160 degrees.  Typically in the Pacific NW the temperature (especially outside) is well below the vapor and flash point of diesel fuels including heating oil and kerosene. If spilled it will not usually evaporate. You can clean heating oil and diesel up with regular dish soap and water.

Can Heating Oil Vapor Explode? Can They Ignite?

Heating oil ignites at 160 degrees.  So unless the temperature is that high an explosion is not a risk.  Fire Code regulating heating oil tanks and placement takes this concern into account.  So typically except in extreme scenarios heating oil vapor does not pose an explosion risk.

If you drop a match into a cup of heating oil at room temperature it will go out.  If you hold a match to the surface of the heating oil in that cup the flame will get large and bright but the heating oil itself will not ignite.  Heating oil needs to be vaporized before it will ignite. It is a combustible fuel so it must be in a vapor form to light.  The vaporizing nozzle of your heating oil furnace turns diesel into a vapor mist easily ignitable.

Can Heating Oil Go Bad?  How Long Can I Store Heating Oil?

Yes, heating oil can go bad. If you are planning to store heating oil for longer than a year, you should use a diesel additive that stabilizes fuel for long term storage. If you are storing the fuel as a back-up where you might go years without using it, you should also consider adding a biocide to ensure nothing grows in your tank. The two biggest threats to your fuel staying in specification are water and biological growth. Biological growth occurs inside the water that can collect in your tank bottom naturally through condensation over time.

Star Oilco treats 100% of our dyed fuels with Hydrotex Powerkleen to ensure that it is stable for storage for over a year. If you need to store it longer than that, we further recommend adding a desiccant breather to scrub moisture out of the air when your tank breaths, which protects it from additional water.

  For more on additizing your heating oil for long term storage please follow THIS link.

Can a Heating Oil Tank be Outside?

Yes, heating oil tanks properly installed outside are perfectly safe and capable of ensuring your fuel stays clean and dry.

Are Oil Tanks Regulated?

Yes, at several different levels. With residential use, there are local jurisdictions’ building permit requirements for installation and safety. With commercial use, there is the same building permit regulation and usually an added level of Fire Marshall sign-off for siting of any tanks. In rural areas, regulations are different if the tank is associated with an agricultural use.

In Oregon and Washington, a 90 day temporary tank for construction purposes (to move from one tank to another in a formal process) is usually allowed, but you should ensure the temporary tank is a double wall tank and is in a safe place. If your tank leaks (or even if there is a suspicion of a leak), the Oregon Department of Environmental Quality and Washington Department of Ecology have an involved process to close out a leaking oil tank.  

Do I Need to do Maintenance on My Furnace? How Often?

Yes, you need to ensure you maintain your oil furnace. Star Oilco recommends getting a tune up annually or at least every other year.  If you are seeking a referral to a HVAC company that specializes in oil heat, call Star Oilco’s office 503-283-1256 and ask for a list of qualified license and bonded companies we recommend. You also want to check your oil furnace for water annually. Star Oilco can stick your tank for water at no charge upon request with a fuel delivery.

One of the great benefits of oil heat is that oil furnaces are known to last for over fifty years if maintained properly. Natural gas and propane furnaces typically wear out every ten to twenty years dependent on their construction. The primary wear consideration on any furnace is the heat exchanger. The heavy steel part takes the flame of burning fuel, transmits this heat to the air, and is then pushed to heat your home. Oil furnaces must be tuned up every year or two to ensure the heat exchanger is cleaned.

If you do not service the heat exchanger, it will collect soot. Soot insulates the heat exchanger unevenly and causes wear that will eventually lead to a crack. If a heat exchanger is cracked, the furnace is no longer safe to operate. Additionally, an annual tune-up will pay for itself by ensuring your furnace is burning at peak efficiency. You will want to replace your furnace air filter regularly on an annual basis.  

How Do I Reduce My Consumption of Heating Oil?

Tuning your furnace annually or every other year is highly recommended. Adjusting the fuel air mixture for the most efficient combustion goes a long way to ensure you use as little heating oil as possible. Star Oilco has witnessed fifty and even seventy year oil furnaces operate at modern efficiencies when maintained regularly over their lives. Today, there are a host of high efficiency oil furnaces manufactured and supported to reduce your cost of fuel.  Additionally, confirming the envelope of your home is not drafty or needlessly wasting heat can go a long way in reducing your heating expenses.

How Can I Reduce the Cost of My Heating Oil?

The price of heating oil fluctuates frequently due to market conditions. Comparison shopping is your best way to ensure you pay the best possible price. One web based tool we have heard customers like to use to save time while shopping for heating oil is Fuelwonk.com.  It is free and easy to use.

Best Practices with a Fuel Tank

Even though the cost of fuel is dependent on the market and out of our control, there are best practices to reduce the amount of oil you’ll need. The temperature you keep your house will affect how much oil you go through. Keeping your temperature higher will lead to more oil burned during the winter months. How insulated your home is will also affect the amount of oil you burn. Having poor insulation will result in having your furnace running hotter for longer periods of time, increasing fuel use. Annual maintenance of your furnace will keep your furnace operating at top efficiencies. Having a well working and operating furnace will keep costs down by not wasting oil on an underperforming unit.

Discounts

Star Oilco also has a number of discounts and programs for price reduction. We offer $.05/gallon veteran and senior citizen discount. We frequently have discounts on Google and our social media pages so make sure to check those out. Mention where you saw it to receive the discount.

Heating oil customers at Star Oilco have the opportunity to enroll in our Equal Pay program. The program allows you to make equal monthly payments on future heating oil deliveries. As an Equal Pay customer, you will receive a discount of .20 cents per gallon on all heating oil deliveries. We also have an Autofill program which dictates you receive our best price as well as automatic deliveries. You don’t have to keep track of your fuel or when you need a delivery. We do the work for you!

If you do not like our price and someone else is cheaper let us know.  We will match their price.

Will Heating Oil be Phased Out?

Heating Oil is a modern fuel that uses today’s heating oils and biofuels.  The investments in research and development for heating oil furnace by the National Oil Research Alliance to use a wider variety of biofuels in higher lower CO2 blends have kept heating oil relevant in many applications.  As a heating fuel, it’s use will become more rural than urban rather than a phase out. As it is today, the use of heating oil will be used where natural gas is not available especially if the temperatures get below zero. Urban adoption of natural gas has increased, as it’s cheaper than heating oil due to increased fracking development of petroleum.

What are “Degree Days?”

Star Oilco uses a Degree Day system for our customers on Automatic Keep-Full Service.  We fill your tank before it needs it automatically. A statistical regression analysis correlates your typical use of heating oil in your home and the weather.  Our systems will track your usual fuel usage and we automatically schedule delivery to keep your tank full.

What is The Energy Content or “BTU’s”?

The technical term “BTUs” refers to “British Thermal Units” which is a measure of energy content of a fuel. The energy content of diesel fuels can vary slightly by regions and specifications of those regions.  In the Pacific Northwest, heating oil is typically Ultra Low Sulfur Diesel with a blend of biodiesel content. This can range from 5% to 20% biodiesel added to the fuel. This means the exact BTU measured for a gallon of heating oil an slightly vary.

Source: US Alternative Fuel Data Center Fuel Properties Comparisons
Ultra Low Sulfur Diesel: 128,488 BTUs to 138,490 BTUs per gallon.
B5 Biodiesel is presumed to be about the same BTUs as ULS Diesel.
B100 Biodiesel: 119,550 BTUs to 127,960 BTUs per gallon.
B20 Biodiesel: 126,700 BTUs to 136,384 BTUs per gallon.

What Do I Need to Know About Long Term Diesel Storage? 150 150 Star Oilco

What Do I Need to Know About Long Term Diesel Storage?

Here’s good advice if you are relying on diesel as a back up fuel in the Pacific NW.

[KGVID]https://staoilcopro.wpengine.com/wp-content/uploads/2018/10/Bugs-Kill-Equipment.mp4[/KGVID]

Now is the time to refill and treat your back up fuel tanks.

Diesel as a back up fuel

Quite a bit of our business at Star Oilco is fueling back-up generators, emergency water pumps, refrigerated trailers and other long term off-road diesel storage requirements. In the Pacific Northwest, biodiesel blending is required by state laws and you need to take an extra duty of care when storing diesel as a back-up fuel.

This means that most off-road diesels and heating oils are ultra low sulfur diesel containing a small quantity of biodiesel.  That means long term storage requires a proactive approach.  You can’t just hope and wait to see what the fuel begins to look after years of storage.

Technical advice from Government Fleet Magazine to help you with storing diesel fuel.

Here is an article from Government Fleet Magazine on the subject which runs through the specifics of long term storage and what causes fuel to degrade when stored.  Government Fleet Magazine – How to Maintain Stored Diesel Fuel.

Star Oilco has also worked up a PDF check list on how to verify if your fuel is in need of freshening or is still in emergency ready shape.  If you are a customer of ours, we will deliver a laminated card version to keep next to your back up generator. If you are not a customer (or outside of our service area) drop us a message below and we will gladly email you the PDF.

For our customers, we recommend that you check the tank bottom fuel quality on an annual basis to make sure the product looks good. If the tank has sat for years and is dark in color (good diesel is bright and transparent – you will notice if it is in bad shape), we recommend pumping the tank out at least partially and replacing with fresh fuel. Often you can also hugely improve the quality of the fuel by polishing the fuel. Polishing is when you circulate fuel from the bottom of the tank through a pump, filter repeatedly in order to remove any sediment or growth from the fuel, and then place this fuel back in the same tank.

Look at your fuel for a bright and clear color.

For stored fuel, you also want to make sure it is stabilized and contains a biocide. Stabilizers prevent the oxidation of the fuel and prevent the effect of metals like lead, copper and zinc, which can react and degrade fuel. For heating oil systems with a return line, for instance, the fuel is flowing through a copper line to the furnace and then back to the tank in a return line.

Use additives designed to prolong the life of your emergency diesel fuel.

Biocides prevent the growth of biological activity in the tank. In scenarios whcontaminated_dieselere micro-organisms like algae, bacteria, yeasts, and other bugs are growing in your fuel, biocides can kill this growth. It is still important to remove the residual grit and other contaminants that are the hallmark of bugs growing in your tank. Usually you remove them by filtration or total turn over of the fuel. If your tank absolutely has to be clean, you can contract a tank professional to enter the tank and physically clean the tank bottom or reline the tank with either fiberglass or an epoxy resin.

Water in diesel destroys fuel quality rapidly. Check your tank for water every fall and spring.

In events where water finds its way into your storage tank, that can also be corrected by pumping the tank bottom. Additionally, you want to put in an absorbent material designed to absorb water and not fuel. If your long term storage tank has water and you are not planning to burn 100% of the fuel in the near future, DO NOT add anything that removes water by distributing into the fuel. Adding a “fuel drier” that actually pushes the water into solution with the diesel will worsen the long term quality of your fuel, not improve it. That water is where bugs find their home to grow in fuel.

Star Oilco will test your fuel at no charge if you have an open account.

Feel free to call us with any questions you may have about long term storage of diesel. Star Oil can also deliver treated diesel ready for long term storage complete with Hydrotex PowerKleen Premium Diesel additive to improve the long term storage quality of your fuel. For biocide, we use Valvtect BioGuard fuel microbiocide to kill any possible biological activity and prevent any chance of it starting.

Can you Bio diesel as a Heating Oil Fuel?

In a recent study, the viability of biodiesel – also known as bioheat – and its use as a heating oil was examined.Star Oilco an experienced provider of BioDiesel Heating Oil

TL:DR Biodiesel up to B20 and beyond do not require equipment changes or settings. Home heating systems have used biodiesel since 2000 and have shown no significant issues compared to standard fuel.

The study reviews pump seal performance, metal interactions, burner combustion and even reviews in-the-field users of biodiesel.

Use of biodiesel reduces GHG (Greenhouse Gas) by 50% – 86% compared to petroleum diesel, according to NORA.

 

In a study from Brookhaven National Laboratory that was submitted to the National Oilheat Research Alliance (NORA), Dr Thomas A. Butcher and Rebecca Trojanowski studied the use of Biofuels in Heating Oil and any possible issues that could result from usage.

Biodiesel mixtures are labeled as B* where the * is the percentage of biodiesel. For example B20 would be 20% biodiesel and 80% petroleum diesel.

By breaking it down into 5 separate studies and a review of actual field use for nearly 20 years, they set out to evaluate the possible fail points of using B20 and higher heating oil blends.

Bio Diesel and Pump Seal Material Evaluation

From the start, the pump shaft seals were identified as the area with the most concern of failure. So, this is where the study began. They identified the most common seals in pumps for North America were nitrile material. The study then focused on this material.

For this part of the study, they took the nitrile material and immersed it in different biodiesel and No.2 fuel blends. They soaked these for 670 hours at 125 °F.  The samples were than checked to see if the hardness changed, looked at swelling, tensile strength, and compression deformation.

Results: There were no significant changes for the nitrite for fuels meeting ASTM standards. This includes biofuel up to B100. The one concern was fuel that had acid numbers above 2 could lead to accelerated degradation. B100 standards call for acid numbers 0.5 and below.

Biodiesel and the Evaluation of Oil Burner Pumps Under Operating Conditions

This second test also dealt with the same seals. The difference in this test was that the pumps were in continuous action. They set up 42 pumps to run for 11 months. A pump would run for 5 minutes and then turn off for a minute. This resulted in 80,000 on/off cycles in a period of 8,030 hours. During this time no leaks were observed in any of the pumps.

Result: There wasn’t any difference in degradation between using B0 and B20.

Exposure of "Yellow Metals" at low temperature with biodiesel

Copper fuel lines are installed in many older oil heating homes. This was due to lower cost and the fact they were easy to manipulate during installation. This could be a problem because No.2 fuel and biodiesel could accelerate the oxidative degradation of the fuels when exposed to copper.

This experiment consisted of using 10 inch tubes filled with different levels of biofuels: B0, B20, and B100. These would be stored at 70 °F  for 6 months in 3 types of tubes: stainless steel, old copper (a fuel line that had been in service for 30 years), and new copper. Most systems only would expose the copper pipes for a very limited time, so 6 months for any exposure is an extreme amount of time.

Results: An acid value of 2 was shown to degrade nitrile material in the earlier experiments. None of the fuel crossed this mark. The closest was B0 in the stainless steel. This fuel got to 1.5 from .04 (where all the fuel started). These tests were considered to represent summer shutdown of a heat-only boiler or furnace.

Exposure of "Yellow Metals" and biodiesel at high temperature

In addition to copper fuel lines, the other major source of yellow metal would be the brass nozzles. Most fuel isn’t in the nozzle long enough to cause any changes, but the fuel left unburned between firings is exposed to higher temperatures then those in the lines. It was decided to try and see if there was changes for this exposure.

The experiment was open top glass beakers with brass and stainless steel nozzles stored in B0, B20, and B100 levels of fuel. This setup was stored in an oven at 175 °F for a week.

Result: The result was a relatively small increase during this time. Even after the experiment was continued for another 4 weeks the numbers represented no significant differences.

Biodiesel Combustion Performance and Flame Sensor Response

The goal of this experiment is to evaluate the proper atomization and combustion performance of biodiesel blends in heating oil systems and to see if there was any issues with flame sensor operation and effectiveness.

The fuel for a home heating oil system requires the fuel to be pushed through a 10 micron filter and then pushed into a fire box at 100 – 150 psi and ignited. This is compared to a diesel engine that have a nominal pore size between 2 and 30 microns and then injected into the system at 20,000 psi.

According to the study, “In comparison to the… diesel engine, heating oil systems are open flame systems and excess air is used to ensure complete combustion. The amount of excess flue gas oxygen is generally between 3% and 6% excess O2 or 15% and 40% excess air to minimize smoke and ensure very low levels of carbon monoxide.” These are usually set by a technician and then re-checked on service calls every 1 or 2 years. “Since properly operating home heating oil systems burn the fuel completely in excess air and emissions are low… Due to this clean combustion, heating oil emissions are typically not measured or monitored, with the exception of smoke and CO.”

The testing was set up first for conventional No. 2 fuel and then adjusted for B100 fuel.

Result: Showed that B20 performed at the same level as regular No. 2 fuel and the bio blend could go all the way up to 50% before the need to adjust the airflow. So, the conclusion was that if the unit is running higher levels of biofuel, the air input needs to be adjust to optimize fuel combustion and reduce CO or smoke.

Review of Field Experience with BioDiesel Blends

Biodiesel blends have been used in the field for heating oil with some using B20 and above since 2005. Part of the study was reviewing customers that have been using B20 above. Of the surveyed providers, none reported a change of any burner or system components.

The report continues to talk about the levels of biofuel that was being used and the condition the fuel was in. Basically it was found that there was no difference from the standard petroleum only fuel.

Conclusion and results of BioDiesel study

  1. Fuels above a certain level of acid content can compromise seals, none of the bio blends reached this and they were statistically similar to petroleum only fuels.
  2. Long term cycling pump showed no leakages with biofuels.
  3. No impact on fuel stored in copper tubing at room temperature was found.
  4. No significant difference on fuel stored with copper at high temperatures and conventional No. 2 fuel.
  5. At higher than B50 concentrations it was found that the burner needed adjusted for best efficiency. B20 will operate at the same level as standard No. 2 fuel.
  6. Finally there appears no real difference in functional use of biofuel vs the use of No. 2 fuel.

So the good news, according to this report, is that if you want to use biodiesel up to B50 there appears no difference in settings or maintenance. As long as a reputable dealer that uses biodiesel that uses ASTM D675 for its B100.

Using biodiesel blends for heating oil reduces greenhouse gases. For more information on this see the NORA report.

What is biodiesel?

Biodiesel is a renewable, clean-burning diesel replacement that is reducing U.S. dependence on foreign petroleum, creating jobs and improving the environment. Biodiesel is commonly blended in a 5% to 20% component with petroleum diesel and can be found available at retail around North America as a blended fuel.  Biodiesel is a low CO2, net energy positive fuel which depending on the feedstock it is made from can vary from a 30% to 80%+ reduction in CO2 emissions compared to petroleum diesel.  Biodiesel is made from a diverse mix of feedstocks including recycled cooking oil, industrial non-food grade spent oils, animal fats, as well as virgin vegetable oils such as canola, soy, and corn oil. For more information see the National Biodiesel Board’s “Biodiesel Basics” page.Simple Bio-diesel chart showing how to make

How is biodiesel made?

Biodiesel is most commonly made from taking an animal fat, used cooking oil, or a virgin vegetable oil and mixing it with an alcohol (such as methanol). This process is called transesterification and it creates two products glycerin and esters (usually methyl esters or alkyl esters which is the chemical name for most biodiesel).  The crude biodiesel is then further processed to remove excess water and other impurities. The standards for commercially sold biodiesel in the US is ASTM D6751.

What does ASTM D6751 mean?

Biodiesel to be sold in the United States must meet an industry standard which is ASTM D6751.  ASTM (American Society for Testing and Materials) D6751 is the specifications for B100 or 100% Biodiesel.  Biodiesel is usually blended with diesel fuel for retail sale.  This specification defines the properties of the biodiesel from the refiner prior to sale to the public. The properties include things like flashpoint, water content, oxidative stability, sulfur ppm (parts per million), and other specifics that this biodiesel needs to be at in order to hit these standards (Source).

Once a fuel is within all these properties it can be blended with diesel, which has its own ASTM standards, for more about ASTM D975 and other fuel specification concerns please see the Changes in Diesel Fuel – Technicians Guide for more and very in depth information.

Can biodiesel be used in normal diesel engines? / Which cars use biodiesel?

Regardless of where you are in the United States there is a reasonable expectation of purchasing biodiesel in your diesel fuel.  Formally, B5 is supported by all major OEMs selling diesel engines in the U.S. In 2016, at least 78 percent of diesel vehicles supported B20 (Source).  Regardless of what your owner manual says about biodiesel fuel, B20 biodiesel is a proven fuel and is automatically presumed for any new diesels on the road. In many parts of the United States B20 is a commonly found fuel at retail stations, commercial cardlocks, and national truck stop chains.

In the Pacific Northwest, where low CO2 emission policy is front and center, biodiesel can be expected to be found in every gallon of diesel sold in some form.

Oregon law says “All diesel fuel sold in the state must be blended with at least 5% biodiesel (B5) if that fuel is going to be used in vehicles. For the purpose of this mandate, biodiesel is defined as a motor vehicle fuel derived from vegetable oil, animal fat, or other non-petroleum resources, that is designated as B100 and complies with ASTM specification D6751. Renewable diesel qualifies as a substitute for biodiesel in the blending requirement” (Source).  Oregon and Washington has plenty of retail and commercial cardlock locations selling above 5% biodiesel as the defacto fuel given the incentives as well as low CO2 mandates in Oregon.

Can biodiesel be used for heating oil?

Yes. Biodiesel has been effectively used as a heating oil for over 20 years. In fact an in-depth report by the Sustainable Energy Technologies Department Energy Conversion Group shows that blends up to B50 can be used without needing to change or adjust your settings. Read our blog for a summary of this report.

Can biodiesel be mixed with conventional / regular diesel?

Most biodiesel that is sold is as a blended form with petroleum diesel. In a blend, the “B” stands for the amount of biodiesel that is included in the product. For example, B20 would be 20 percent biodiesel and 80 percent petroleum diesel. Biodiesel can also be combined with renewable diesel – a blend of B20 would be called B20/R80 diesel.

Can biodiesel be used in diesel generators?

Yes. In fact, Oregon is one of several states that require biodiesel be blended into all diesel fuels. That means this fuel has been used successfully in the fuel supply for years. As with any fuel that can sit for extended amounts of time, we recommend you take proper precautions, such as using additives, to ensure your fuel is ready to be used when needed. If this is a concern, please contact us – we would love to talk to you about your storage needs.

Can biodiesel be made from animal fat?

Yes, biodiesel refers to (according to the National Biodiesel Board) a methyl ester made from chemically reacting lipids with an alcohol to produce fatty acid esters. This is called transesterification. The lipids could be sourced from many different types of oils, such as vegetable, soybean or animal fat based oils/tallows. For a deeper dive into some of the different types of feedstocks, read our blog.

Can biodiesel be used in airplanes?

Yes and no. There have been several tests using biofuels but fuel for aircrafts is different than regular diesel. Fuel gels at a plane’s flying altitude so aircrafts can’t use regular diesel or biodiesel. Several tests with biofuels have proven successful. Read more about the use of biofuels in the future.

Can biodiesel freeze?

Gelling is the term used for diesel fuel starting to freeze. The paraffin present in diesel starts to solidify and at lower temperatures, it can start to solidify and crystallize. Some blends of biodiesel at B20 and higher will gell at a higher temperatures than petro diesel. During the winter months, it’s important to use additives that combat this or use lower percentages of biodiesel for your fuel. In low enough temperatures, even petro diesel will freeze.

Can biodiesel replace oil? / Can biodiesel replace diesel / fossil fuels?

At this time, no. While the quality of the fuel for biodiesel and renewable diesel is as high as the petrodiesel we have today, the production of these fuels can’t meet the demand that is needed. This has to do with available feedstock and infrasturcture to recycle usable wastes.

The long answer to this question, though, is YES. As technology advances, there may be a time that all fuel is derived from waste and plant crops instead of petroleum.

For an idea where the market is going and how much fuel we are using here is a little bit more information on current usage.

In the early 2000’s, the biodiesel market was about 25 million gallons. In 2016, the market had grown to 2.8 billion and it’s still increasing. The on-road diesel demand is 35 billion to 40 billion gallons. The industry goal is to be producing 10 percent of the transportation market by 2022 (Source).

Which biodiesel is best?

Biodiesel that meets the ASTM D6751 is the best. While making your own biodiesel isn’t hard, keeping the fuel filtered and free of excess water is challenging. Finding a reputable provider that uses fuel that meets specs and also filters and treats your fuel like Star Oilco helps ensure you’re using the best fuel possible.

Which is biodiesel plant/crop? What crop/plant produces/yield biodiesel?

Any plant that produces an oil can be used to produce biodiesel. The plants and crops that are most likely to be used, would produce a lot of oil for the amount of work that goes into growing them. Some of the experimental crops are ones that grow in areas that don’t produce quality food, like Camelina sativa. A member of the mustard family, it grows well in poor soil and harsh conditions and doesn’t displace crops that produce food.

Here are the blogs we have posted so far about some of the biodiesel feedstocks that have been tested and used.

Feedstock: Babassu oil & Beef Tallow
Feedstock: Borage Oil & Camelina Oil
Feedstock: Algae Oil & Canola Oil
Feedstock: Castor Oil and Choice White Grease
Feedstock: Coconut Oil and Coffee Oil
Feedstock: Evening Primrose Oil and Fish Oil
Feedstocks: Hemp Oil & High IV and Low IV Hepar
Feedstocks: Jatropha Oil, Jojoba Oil, & Karania Oil
Feedstocks: Lesquerella Oil & Linseed Oil
Feedstocks: Moringa Oil & Neem Oil
Feedstocks: Palm Oil & Perilla Seed Oil
Feedstocks: Poultry Fat & Rice Bran Oil

Which is better: biodiesel or diesel?

Biodiesel has advantages of producing lower emissions, providing lubricity to the moving parts and being produced in the United States.

Diesel is more abundant, is easily created from crude oil, and has a lower gel point.

Which is better depends on what you are looking for.

Which states mandate biodiesel?

According to AFMP (American Fuel & Petrochemical Manufacturers):

  • Minnesota: Has a B2 requirement year round (September 2005) and a summer requirement of B20 (May 2018).
  • Oregon: Requires a B5 reguirement year round (July 2007).
  • Washington: Requires 2% of the diesel sold in Washington to be biodiesel (December 2008). This can be substituted with Renewable Diesel (July 2009).
  • Pennsylvania: According to AFMP, “2% biodiesel for on-road compression ignition engines one year after annualized in-state production reaches 40 million gallons, 5% biodiesel (100 million gallons), 10% biodiesel (200 million gallons), and 20% biodiesel (400 million gallons)” (July 2008). Renewable diesel can substitute for up to 25% of this requirement, in addition to heating oil and off-road diesel (May 2011)
  • New Mexico: Requires B5 for all diesel vehicles (July 2012).

Which countries produce biodiesel? / Which countries use biodiesel?

global biodiesel production by country
Biodiesel is produced around the world, led by the U.S., Brazil and Germany.

The US produced 6 billion liters in 2017 or about 1.6 billion gallons. This website has the exact numbers for 2017, 2018 and some of 2019 production of biodiesel in the U.S.

Biodiesel in the US is largely made from soybeans at this time.

Will biodiesel damage my engine? / Will biodiesel damage my car?

Biodiesel can be used in any car or engine that is using diesel. Biodiesel is a solvent this means that it may start cleaning the tank or pipes that previously just used petroleum fuel, for this reason fuel filters may clog initially.

How will biodiesel help save money?

It depends! If the price of a barrel of crude rises to a high level, biodiesel can be cheaper. In addition, if RIN’s are available (basically a credit for using biodiesel), they can lower the price of biodiesel and make it less expensive to use and purchase.

How will biodiesel help reduce pollution?

Petrodiesel uses crude oil, which is trapped CO2 from ages past. When it is burned, it releases this CO2 back into the air.Average Biodiesel Emissions Compared to Conventional Diesel When you use biodiesel, you’re using CO2 that is being captured by the growing plants or the waste. This is current CO2 you aren’t adding to the net sum in the environment.

As for regular pollutants, here is a chart that shows what using biodiesel does compared to conventional diesel. There is a significant reduction to pollutants that are expressed through the exhaust.

How long will ecodiesel last? / How long can biodiesel be stored?

Diesel, including biodiesel, does go bad after awhile. Diesel fuels adhering to ASTM specification should be safe for storage up to a year without additional treatment and testing. If you are storing diesel for long term use, it is a good best practice to treat the fuel with a biocide and oxidative stabilizer to ensure that the fuel stays within specification and nothing will begin to grow in your fuel tank. The biggest enemy of long term diesel storage is water and dirt entering the fuel through a tank vent. As temperatures change, a tank will breath, pulling in air and moisture from outside. Keep your fuel within specification by ensuring there is no water in the tank and that outside contaminants can’t get into a tank.

Where biodiesel is used? / Where is biodiesel used in the world?

Biodiesel use is encouraged by many countries and usage has increased greatly since 2001. This graph from the U.S. Energy Information Administration shows that the U.S. used 2.1 billion in 2016 or about 22% of the total amount of biodiesel used that year. Wikipedia lists 31 countries and explains the amount of biodiesel they use each year. World biodiesel consumption, 2016

Where to buy biodiesel?

If you live in Oregon, every gas station has at least 5% biodiesel. Cardlock locations throughout the states have stations with biodiesel blends. For other locations, this site is a great resource.

Where can biodiesel be used?

Legally, it can be used anywhere although some biodiesel derived from palm oil is restricted in certain countries.

When / where was biodiesel invented?

The definition of diesel is a liquid that uses compression and oxygen to ignite without the use of a spark. Rudolf Diesel created the diesel engine in Germany. The design for engines first used coal dust suspended in water and later vegetable oils, such as peanut oil. These fuels were later abandoned when petroleum became abundant and cheaper to produce.

Where does biodiesel fuel come from?

In the United States, the primary source for biodiesel is soy beans. According to the U.S. Energy Information Administration, the feedstocks break down as such:

  • Soybean Oil – 52%
  • Canola Oil – 13%
  • Corn Oil – 13%
  • Recycled feedstocks – 12%
  • Animal Fats – 10%

Even with Soybean oil as the primary source, the remaining meal is used to produce food for animal feed. For more information on feedstocks of biodiesel, here is an ongoing blog we have been working on to examine the resulting fuels produced by the various feedstock.

Where are biodiesel plants?

Here is a list of sites in the United States.

When did biodiesel begin?

The original diesel engine ran on peanut oil, so technically biodisesel was first used in the 1890s. Most oils in the 1800s were from bio stocks. It wasn’t until petroleum became abundant and thus cheaper that biofuels and oils were abandoned for this cheaper source.

When does biodiesel gel?

The feedstock determines when biodiesel will gel. The most common feedstock is soy, which has a cloud point of 0°C (32°F) for B100. Petroleum diesel has a cloud point of -45°C (-49°F) to -7°C (19°F) (Source). Cloud point refers to when the paraffin begins to crystallize and the fuel looks a little cloudy.

Biodiesel and petrodiesel is usually blended and this lowers the cloud point of biodiesel in the fuel considerably. In addition, additives are frequently added during cold weather that further lowers the cloud point.

When is biodiesel day celebrated?

National Biodiesel Day is March 18th, which is also Rudolf Diesel’s birthday. August 10th is International Biodiesel Day, a celebration of Rudolf Diesel’s prime model running for the first time on August 10, 1893.

Who invented biodiesel?

The diesel engine is defined by “any internal-combustion engine in which air is compressed to a sufficiently high temperature to ignite diesel fuel injected into the cylinder, where combustion and expansion actuate a piston.” Until petroleum was developed as a cheaper alternative, animal and vegetable oil was used. One of the first fuels used in the diesel engine was peanut oil, and thus biodiesel was born.

Can you use 100% Biodiesel even in the winter?

The answer is YES.  While biodiesel has a lower cloud point then petroleum diesel there is a technology by Optimus Technologies called the Vector System. This allows a truck to start on regular diesel until it gets up to temp and switch over to run on up to 100% biodiesel.  The City of Ames, Iowa is one success story of this technology. (Story Here)
