What is biodiesel?
"Biodiesel is a renewable, oxygenated fuel made from a variety of agricultural resources such as soybeans or rapeseeds. Biodiesel is nontoxic, biodegradable, and suitable for sensitive environments."

The question is often asked, "How much biodiesel can be used?" the answer to this question is relatively simple...
The last time we checked with the U.S. EPA in 2009, the "allowed" concentration was B100, which is to say 100% biodiesel; in other words no petroleum based diesel fuel at all.
B100 however is NOT legal for use within the State of California, as CARB (California Air Resources Board) put it to us... "Biodiesel is NOT a certified fuel under title 13 of the California Code of Regulations" so therefore we limit its legal use to B50 or 50% biodiesel to 50% ULSD (Ultra Low Sulfur Diesel). Now enter the engine manufacturers, many who have weighed in on this subject allow no more than 20% and a few have limited the blend level to 5%. (See Table in Left Column)

Biodiesel does have some positive benefits, however like anything it also has some negatives as well, we will soon add to this topic which much detail about biodiesel, ULSD and exhaust emissions as related to nonroad equipment that make use of Diesel engines as prime movers.
