What is Biodiesel?

Biodiesel is a clean-burning alternative fuel produced from vegetable oils and animal fats through a chemical reaction and meeting ASTM 6751. Biodiesel alone contains no petroleum diesel, but it can be custom blended with petroleum diesel at any level. Blends are available 2% Biodiesel (B2) up to 99% (B99).

The most commonly used blends are B2, B5 and B20. Biodiesel is not the same as raw vegetable oil. It is produced by a chemical process called transesterification which removes the glycerin from fat or vegetable oils.

BioDiesel Compatibility

Most engines are compatible up to 20% blend (B20) without effect to the internal seals, gaskets, and hoses. Each engine manufacturer has listed its maximum biodiesel blend to meet warranty and engine specifications. Contact the engine manufacturer for more details or click the links provided below to be directed to common manufacturers.

Typically, standard storage and handling procedures used for petroleum diesel can be applied to Biodiesel. Components made from fluorinated polyethylene, fluorinated polypropylene, Teflon, Teflon lined, or Viton are recommended for fuel storage.
