General

Biodiesel is the name given to a clean-burning alternative to diesel fuel. It is produced from a broad range of renewable resources including soybean oil, animal fats and recycled cooking grease. Biodiesel is the first and only EPA-designated advanced biofuel in commercial-scale production across the country and can be used in existing diesel engines without modification. Biodiesel can be used alone, or blended with petroleum diesel in any proportions.
Biodiesel contains no petroleum, but it can be blended at any level to create a biodiesel blend.
When biodiesel is blended with petroleum, it becomes a biodiesel blend. It is often labeled with the amount of biodiesel found in the fuel, B20 for example is a blend of 20 percent biodiesel and 80 percent petroleum diesel.
No. Biodiesel goes through a process called transesterification to remove glycerin from the oil. Fuel-grade biodiesel must meet the strict industry standards of ASTM D 6751 in order to insure proper performance.
Biodiesel is a diesel fuel replacement, made from excess renewable fats and oils. Using a production process known as “transesterification”, these feedstocks are converted into a class of compounds known as fatty acid methyl esters (FAME) (refer to the definition above). Renewable Diesel is a fuel that utilizes the same renewable feedstocks used to produce biodiesel, with a production process more like diesel fuel production. These processes yield compounds that are chemically indistinguishable from petroleum diesel fuel. While these two fuels are distinctly different, each offers performance improvements over the use of petroleum, such as the reduction of at least 50% greenhouse gas emissions.

Using Biodiesel

After millions of miles on the road, biodiesel has proven itself as a reliable renewable fuel. It diversifies the US fuel supply, supports American jobs and adds back to the US economy.
Biodiesel is registered as a fuel and a fuel additive with the Environmental Protection Agency (EPA). It also meets clean diesel standards set by the California Air Resources Board (CARB). B100 has been designated as an alternative fuel by the Department of Energy (DOE) and the US Department of Transportation.
Biodiesel can be used in any diesel engine with little or no modification to the engine or fuel system. Biodiesel has a solvent effect that may release deposits accumulated on tank walls and pipes from previous diesel fuel storage. The release of the deposits may clog filters initially and precautions should be taken. Ensure that only fuel meeting the biodiesel specification is used.
Biodiesel works seamlessly with existing infrastructure and vehicles. In fact, 78 percent of the diesel vehicles coming off the production lines today are approved for B20. Among U.S. heavy-duty truck segments, every engine manufacturer supports B20 in their engines except Daimler’s Detroit Diesel, which remains at B5.
Biodiesel is available nationwide and blends over 4 percent are required to be labeled at the pump. Look for the Black and Blue biodiesel sticker when filling up. Biodiesel can be purchased through distributors or at retail locations.
Yes. Biodiesel blends of up to B20 can be used in cold weather. Just like regular diesel, biodiesel can gel in cold temperatures, so precautions need to be taken. Find out more in the cold weather section of our Biodiesel Facts Sheets page.

Sustainability

Yes. Biodiesel is made from renewable by-products of food production and is the most diverse fuel in the world. It reduces greenhouse gas emissions by up to 86%, gives back energy to the environment and reduces smog to make our air healthier to breathe.
Biodiesel returns energy to the environment. For every unit of fossil fuel required to make biodiesel, it returns 3.5 units of renewable energy. That’s the best of any U.S. fuel.
No. Biodiesel is made from by-products, even soybean oil. Soybeans are grown primarily for meat production, the oil is what is left. Biodiesel has not caused changes in agriculture production.
