Biodiesel (FAME)
Biodiesel is a renewable, biodegradable fuel manufactured domestically from vegetable oils, animal fats, or recycled restaurant grease. (Alternative Fuels Data Center: Biodiesel Fuel Basics (

• Must Be Mixed With Diesel Fuel: Most OEMs limit biodiesel content to 20% (with some only allowing 5%) some examples are B20 (biodiesel mixed with 80% diesel) and B10 (biodiesel mixed with 90% diesel).

• Cold Weather Performance: Biodiesel has a higher cloud point than diesel and renewable diesel and as temperatures drop, you will notice a loss in power as the fuel gels. In very cold weather conditions it is recommended to perform checks to determine the optimal biodiesel blend for your conditions.

Renewable diesel (HVO)
Renewable diesel is a fuel made from fats and oils, such as soybean oil or canola oil, and is processed to be chemically the same as petroleum dies

• More Flexibility: Renewable diesel is a replacement for diesel and can be used to fully replace diesel or blended with any amount. Renewable diesel can be made from multiple feedstocks and at plants that also produce sustainable aviation fuel.

• Fewer Emissions: an NREL study found renewable diesel reduced both carbon dioxide and nitrogen oxide emissions when compared with petroleum diesel. California’s Low Carbon Fuel Standard Certified Carbon Intensities shows renewable diesel reduces carbon intensity on average by 65% when compared with petroleum diesel.
