Star Oilco Speaks On Decarbonizing Heavy Duty Trucks

Decarbonizing Heavy Duty Fleets By Using B99 Biodiesel.

Mark Fitz joined the Clean Cities Coalition Mindful Mobility Tech Talk series for their High GHG Reductions webinar. Mark spoke on the benefits of B99 and how fleets can begin decarbonizing their emissions today!
On September 28th, 2022, three representatives were invited to speak on how they are not only saving large amounts of energy but are also having a big impact on reducing greenhouse gas emissions.

B99 Biodiesel reduces CO2 footprint of a 105,500 GVW truck and trailer by more than half at a lower cost than petroleum diesel.

How Can I Utilize B99 or B100 for Decarbonizing My Own Fleet?

Star Oilco uses The Vector System developed by Pittsburgh-based Optimus Technologies. The Vector System allows upgrades for any medium or heavy-duty engine to operate on 100% biodiesel. This is the only EPA-compliant biodiesel engine system and can be installed in as little as 12 hours. Contact Optimus Technologies or reach out to Star Oilco locally to learn more about The Vector System.

Star Oilco’s Field Test

Star Oilco fielded the Optimus Technologies system on our 105,500 GVW truck and trailers.  We began with a single Freighliner truck and trailer operating a Cummins ISX as a trial.  This truck’s typical route was approximately 305 miles round trip from Portland, Oregon to Grays Harbor, Washington.

Over the last year and a half this truck has performed amazingly well. The only maintenance concern is swapping the fuel filters more regularly with every oil change.  Neither drivers nor our Elog system noticed differences in mileage and power.  On a few occasions a loss of power was experienced requiring an in between service fuel filter swap.

Biodiesel as a Heavy Duty Low CO2 Solution

Save money with Low CO2 Biodiesel in your heavy duty fleet.

In Oregon the state ensures there is a cost associated with the CO2 intensity of a fuel.  This is why Biodiesel is consistently lower cost than petroleum Diesel fuels on the West Coast.  Get ahead of this curve and ensure your fleet benefits.


Why B99 Biodiesel was used in the past?

Prior to 2007 emission systems on modern diesels B99 Biodiesel was commonly used by fleets.  The fact that Biodiesel is a domestic, renewable and low CO2 fuel with a benign tail pipe emission made it popular.  B99 was the preferred fuel of dozens of fleets in the Pacific NW.  After the EPA requirements starting in 2007 which added particulate traps, SCR, their dosing systems, and the general complexity of these clean diesel systems on modern diesels, B99 became problematic.  Specifically the Tier 3 and Tier 4 diesel emission systems had a habit of choking on high blends of Biodiesel approaching B99.  This issue has been solved by Optimus Technologies Vector System.

Why B99 Biodiesel is the solution for Heavy Duty Diesel fleets seeking a Low CO2 solution today?

The Optimus Technologies Vector System provides the solution by enabling two tanks of fuel.  One tank dedicated to the diesel or R99 Renewable Diesel and the other tank dedicated to B100 or B99 pure Biodiesel. These systems optimize the systems of your modern Diesel fleet while also optimizing the performance and realities of the emission systems.

Star Oilco at the National Biodiesel Conference in Las Vegas

Mark Fitz, the President of Star Oilco, was invited to speak in front of a bunch of soy bean farmers on the subject of decarbonizing Heavy Duty diesel fleets.  Below is a walk through of his view on where diesel fleets can go to cut their CO2 emission in half or more today. NOTE: Mark Fitz’s portion begins at 18 minutes.

Oregon Diesel Taxes Explained 1024 768 Star Oilco

Oregon Diesel Taxes Explained

How Oregon Diesel Taxes Are Calculated

As of January 1st, 2022 Oregon is raising Fuel Taxes to $.38 a gallon. (source) The prices in this article have been updated to reflect that.  There will be another $.02 a gallon fuel tax increase set in 2024 as well.

Oregon is unique in its handling of diesel. All fuel isn’t used or taxed the same in the state of Oregon. First off, there is no sales tax for any fuels. The taxes that are charged for diesel are divided into 3 categories: dyed diesel, PUC use and everyday road use or “auto diesel.”  The big difference in pricing is how the diesel is used and the size of the vehicle using the diesel.

 

Oregon Fuel Taxes in a Nutshell

Off-road diesel

If a vehicle is burning diesel “off-road” like a back-hoe, agricultural use, generators or similar use, the fuel is not taxed by either the federal government or Oregon State. This fuel is also dyed red to show it is for off-road use only. If you use dyed red off-road diesel fuel in an on-road vehicle and you get caught, the state of Oregon can and will likely fine you $10,000. Yes, we have seen them do this in recent history.

On-road diesel (auto diesel)

If your vehicle is below 26,000 gross vehicle weight, Oregon charges a per gallon vehicle tax.  This tax is paid at the gas pump, is collected by the retail or commercial cardlock location, and you do not have to consider any additional taxes other than buying on-road fuel.

On-road diesel (P.U.C. diesel)

If your vehicle is above 26,000 gross vehicle weight in Oregon, you pay a weight mile for your vehicle’s state diesel tax.  This cost per mile depends on your registered vehicle weight with Oregon. It is anecdotally assumed at the top weights over 80,000 lbs of gross vehicle weight, this tax is equivalently more than double the per gallon cost of auto diesel bought at a retail location.  This class of diesel usage requires extra P.U.C. filings and vehicles over 26,000 GVW have special P.U.C. plates denoting their class as it relates to diesel fuel tax.

Oregon Fuel Taxes for a Layperson

On-Road Diesel (Auto Diesel)

The easiest one to understand is on-road diesel, also known as “auto diesel.” Most non-truck vehicles driving on streets, roads, and highways around Oregon fall into this category for use, or as you can see in this picture, a smaller motor home or RV (recreational vehicle).  This fuel is the one you see at a pump at a retail station. Its price includes federal tax, state tax and any applicable local taxes.

Current auto diesel taxes in Oregon for vehicles under 26,000 GVW (gross vehicle weight):

  • Federal tax rate is $.244 per gallon
  • The state tax rate is $.38 per gallon

In addition to these, local municipality and cities have their own taxes that can be added to the price of fuel. To make it even more complicated, some cities charge a different tax amount based on time of season; specifically Newport and Reedsport who charge a few more cents during the summer months. Currently the highest additional taxes are in the city of Portland, Oregon at $.10 per gallon. Source.

Example:
Fuel price at the pump is listed at: $2.989

  • Federal                =$.244
  • State                    =$.38*
  • Portland             =$.10

For a total of                =$.724 per gallon in taxes

The actual cost per gallon would be $2.265. This includes the OPIS (Oil Price Information Service) wholesale price, transportation costs, and the margin the retail station adds to pay its bills (usually $.15 to $.40 depending on the provider).

*January 1st, 2022 Oregon State Tax fuel went up to $.38 per gallon for Oregon Motor Vehicle Fuel Tax. Oregon Use Fuel Tax also went up to $.38 a gallon.

 

Dyed Diesel also called Red Diesel is used for vehicles that don't drive on public roads.

Dyed diesel, also called red diesel, is used for vehicles that don’t drive on public roads.

Off-Road Dyed Diesel

Dyed diesel, also called farm diesel, marked fuel, or red diesel, is a fuel that has an added dye in the mix. The dye, usually solvent red 26 or solvent red 164, doesn’t cause any change in the operation of an engine versus using regular clear diesel. The dye marks the taxable status of the fuel.

This fuel is intended for only off-road equipment and vehicles. Farm equipment, construction vehicles and any other vehicles that don’t drive on public roads can use this fuel. In addition, any engine or oil heater that burns diesel is allowed to use dyed diesel. Those that have heating oil delivered are purchasing dyed diesel.

The benefit of this fuel is that you save state, federal, and city or municipal taxes. Acquiring this fuel as a customer usually requires access to a commercial fueling station or hiring a fuel company to deliver the fuel. This is likely to prevent accidental use of this fuel in an on-road vehicle. Anyone found using dyed diesel in an on-road vehicle will be fined. Fines are either $10/gallon or $1000 per violation, whichever is greatest (Source). To ensure that diesel users aren’t abusing this fuel, police officers can “dip” a tank; usually by sticking a clear tube into a tank and verifying the color of the fuel.

Oregon PUC Permit and IFTA for vehicles over 26,000 GVW

Oregon PUC Permit and IFTA for vehicles over 26,000 GVW

Oregon PUC Permit

While PUC stands for “Oregon Public Utilities Commission”,  it is the Oregon Transportation Department who regulates fuel taxes and PUC plates.

PUC plates are required by vehicles over 26,000 GVW. Oregon PUC Permit or heavy motor vehicle trip permit refer to vehicles that are at this weight and up to 80,000 GVW. They also include an Oregon PUC card number and a log book that shows fuel usage. View Table “A” tax rates.

These vehicles are only required to pay the federal tax at the pump. They are then required to log the mileage they drive and pay an amount based on weight, number of axles and miles. The heavier the vehicle, the more wear and tear on the road, so the higher the tax.

Oregon per Mileage fuel tax for vehicles between 26,000 lbs and 80,000 lbs.

Source : Oregon Department of Transportation 

The fees are applied for a whole trip. Say a truck is scheduled to drive 100 miles round trip to deliver watermelons. A vehicle driving 100 miles that weighs over 44,000 but less than 46,000 would be charged $0.0907 per mile or $9.07. Trucks that are driving a full load of product and an empty load back pay for the total miles of the trip, including the miles they are driving empty. In the above example, even if half the miles were at the 26,001 rate for the return trip, the taxable rate is the full load price.

Any commercial vehicle that is over 80,000 GVW would use the Table “B”, which is similar but includes different pricing based on the number of axles, not just weight.

Oregon per Mileage fuel tax for vehicles between 80,000 lbs and 105,500

Source: Oregon Department of Transportation

As the vehicles get heavier, the amount of axles used change the price. In the chart, 5 axles at 81,000 miles is $0.2115 a mile and a vehicle with 9 axles and the same weight is $0.162 a mile.

For any additional questions about the PUC plates, tax rates and trucking information in Oregon, please contact ODOT at 503-378-5849.

IFTA – International Fuel Tax Agreement

IFTA is for the same vehicles over 26,000 GVW if they drive into more than one state or into Canada. This helps simplify the reporting process of taxes, refunds and mileage for vehicles that travel in more than one state. These commercial motor vehicles are required to file quarterly with their base jurisdiction and the amount of taxes that they might have paid at the pump is recorded. Then they either pay the difference or receive a refund if they overpaid. Prior to IFTA, trucks would need a permit for every state they operated in.

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.

In-depth look at Biodiesel as a heating fuel

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.

  6 Reasons to Use Wet Hose or Mobile Onsite Refueling

On Site refueling or “Wet Hosing” is a preferred method for fueling these days. Fleets of all sizes prefer getting their fleet fueling delivered after hours in their yard. The reasons are numerous but at the top of the list, labor is the driving force behind it.

Shaving off even fifteen minutes of labor–which is one of the two highest costs for most fleets, right after diesel–can have a huge payback to the bottom line.

If your fleet is consistently on overtime or short that one extra hour of legal driver time, picking up fifteen to thirty minutes per truck a few times a month can be a huge opportunity. If your drivers always seem to be bleeding into overtime or missed stops, you want on-site fueling.

Streamlining their route without a consideration for fuel will pay back rapidly. With a simple change in what a driver has to consider at the start and finish of their day, efficiencies are immediately seen with wet hose fueling. Most of all, this is seen if you are pulling your drivers out of the productivity killing vortex that is truckstops. Truckstops may show a good diesel price but they are making it up when your drivers wait in line inside the store while on the clock.

Call Star Oilco if you have questions and want to examine the payback value of Wet Hose Refueling compared against your current vendor for diesel. You might be surprised how much it will save you in time, money and management effort.

Six reasons why you should consider wet-hose diesel fueling:

  1. Driver Time – The most valuable resource your fleet owns.

    • Truck drivers are a limited resource and they cost more than you can usually measure in money alone. Without calculating the lost productivity of your truck, you are paying over $10 each time your drivers stop for fuel. The out of route stopping, refueling, and getting back on the road time could be half hour of lost time. As the average fill up we see is under 50 gallons, fueling your own trucks will cost you $.20 to $.50 a gallon in labor costs alone.

  2. One More Stop – Picking up productivity in your fleet.

    • Getting drivers on the road and without a reason to be out of route pays back dividends. If you pay productivity bonuses, your most productive drivers will thank you as well. Even in fleets where pay is by stop, not based on hourly wages, the ability those few times a year when drivers are so busy they are bumping up against DOT work rules, they will thank you for the convenience of being ready to go the start of each shift and not having to worry about that one more stop on the way back to base. A few extra stops a year is often worth thousands of dollars to your bottom line–more than a cost of a tank of diesel.

  3. Control Fuel Taxes – Track your taxes without chasing paper receipts.

    • Pay the right taxes. We have audited and seen where mobile on-site refueling pays back thousands of dollars in savings. Typically from just this often unnoticed needless expense alone. In Oregon many small towns have add-on taxes of their own that hide out in your fuel bill. Portland, Oregon’s diesel tax is a $.10 a gallon (or more for weight mile). Regardless, you can avoid these taxes and nail down a totally known cost of fuel.

  4. Control Your Type of Fuel – Ensure you are getting Premium Diesel, Dyed Diesel, or B20 Biodiesel.

    • If you are trying to guarantee the highest performance in your fleet the quality of your diesel matters. To guarantee you receive Premium Diesel, ensure one point of responsibility for the diesel fueling of your equipment.
    • Easily track what fuel went where for tax purposes. Wethose fueling provides the gallons moved by piece of equipment, license plate, and even VIN if that’s what you want it tracked by. Make fuel tax reporting easy and consolidated.
    • If you are working to guarantee a low CO2 footprint for sustainability reasons. Wethose fueling services are a great way to simplify that effort. Commercial prices for B20 Biodiesel are often more competitive than retailers selling the fuel as premium product as well. Additionally, with a single fuel vendor you can track back the source of the fuel for CO2 or other footprint analysis. Know what your impacts are.

  5. Easily integrates with cardlock and other fleet cards onto one bill.

    • If you have a major hub with a critical mass of trucks in town, wet-hosing yPride Advantage Sample Cardour fleet can pay back rapidly. Even if the majority of your fleet is over the road and out of town, on-site refueling can be a money saving proposition. You can also integrate it seamlessly with a Pacific Pride, CFN, Fuelman, Voyager or other fleet card program as well. Star Oil can provide a Pacific Pride or Fuelman card that will work over the road consolidating all your fuel into one bill. Star can also accept Fuelman, Comdata, WEX or Voyager and bill those fleet cards directly with onsite refueling. If your fleet uses one of these national fleet cards, call us to move to wet hosing. We bill directly to the card and license plate of each one of your trucks. (For further reading on corporate fleet card security features please read our article on Upgrade your Fleet Card’s Security Features.)

  6. Cost Plus Diesel – Budget to know every day you are getting a good wholesale rate for your fleet.

    • Star Oilco can connect your fleet to an agreed and easily verifiable cost plus supply agreements. Be it OPIS Average or Low Rack Plus agreements, we can guarantee you have a good wholesale price of fuel.  You can also use B20 Biodiesel or Renewable Diesel fuels at a discount price to reduce your fleet’s emissions if that is a priority for you.  Onsite refueling will provide a simplified fleet management experience for both your drivers and your Accounts Payable department. Call us if you want to talk about what this can do for your business.

What is the benefit of Premium Diesel versus normal diesel?

Premium Diesel delivered in Oregon and Washington with every gallon of Star Oilco diesel.

Are you clogging filters, seeing corrosion, suffering repeated DPF regens, or fighting biological growth in your tank?

Premium Diesel improves engine performance and reduces DPF regens.

Premium Diesel with routine tank maintenance is the solution to your problem.

Premium diesel provides real benefits to the long term maintenance cost of any diesel fleet.

Hydrotex PowerKleen Premium Diesel has a higher cetane, an aggressive detergent for cleaning injectors and tanks, pushes water out of the fuel keeping it dry while traveling down your fuel rail, as well as stabilizes the fuel to ensure it does not begin to grow algae or other biological problems in your tank.

Hydrotex PowerKleen Premium Diesel has plenty of benefit for a very small additional cost.  The most profound and not highlighted is the effect on long term storage of tanks and what your bulk storage tank bottoms look like long term. Namely that the corrosion inhibitors, moisture demulsifiers and stability benefits of Premium Diesel will pay back dividends for your entire fleet.  As time passes the bottom of your tank begins to age and collect anything that might fall out of solution.  Premium diesel will significantly reduce these danger particles that can get into your fleet’s fuel system.  Premium diesel not only improves the active daily performance of your fleet, it also prevents the long term problems that build up in fuel storage.

A first hand extreme example.  Recently we have seen where a customers sprinklers put a huge quantity of water in their storage tank and the additive kept that fuel bright, clean and not growing fuel algae.  Upon sending the sample to the lab of course water content was higher than you want, but that fuel was in great shape considering this extreme failure of fuel quality assurance. Controlling and preventing for the unforeseen is worth the effort.  What might have been a disaster costing tens of thousands in down equipment was an oddity we were able to fix for them in a few hours.  All because additive fuel kept that fuel within specification even in the most extreme of scenarios.

Every Question We Have Been Asked About Biodiesel

Every Question We Have Been Asked About Bio-diesel

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.

United States Month Biodiesel Production 2017 to 2019

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)
