Biodiesel blends are being used in a number of heavy-duty vehicles throughout the country. The most common blend of biodiesel is B20 (20% biodiesel / 80% diesel), but B100 (neat biodiesel) and blends of less than 20% biodiesel can also be used.
Vehicles that have successfully used biodiesel include school and transit buses, refuse haulers, military support vehicles, farm equipment, and national park maintenance vehicles. Biodiesel fueling of light-duty diesel vehicles is less common. It is important to always consult your vehicle manufacturer to make sure they approve the use of biodiesel in their products.
Fleets looking to comply with the Energy Policy Act of 1992 (EPAct) must use fuel blends that contain at least 20% biodiesel. For more information on EPAct go to the EPAct Web site. For more information on fuel blends of 20% biodiesel or less, please see our site on fuel blends.
