Biodiesel can be used as a pure fuel or blended with petroleum in any percentage.
Biodiesel blends are denoted as “BXX” with the prefix ‘B’ representing Biodiesel and the “XX” representing the percentage of Biodiesel contained in the blend i.e.: B20 is 20% Biodiesel, 80% petroleum diesel.
Common blends include B2 (2% Biodiesel, 98% petroleum diesel), B5, and B20. B2 and B5 can be used safely in most diesel engines. B20 has demonstrated significant environmental benefits.
