What Is Biodiesel?

Biodiesel is a renewable fuel made by a chemical reaction of alcohol and vegetable or animal oils, fats, or greases. Through a refinery process called transesterification, the reaction removes the glycerin -- a by-product that is not good for your engine -- which can be made into soap. Biodiesel can be used in any diesel engine in pure form or blended with petroleum diesel at any level. Even a blend of 20% bio- and 80% petroleum diesel will significantly reduce carcinogenic emissions and gases that may contribute to global warming.

Biodiesel is non-toxic, biodegradable diesel fuel made from vegetable oils and animal fats. It can be used straight in any diesel engine, or mixed with petroleum diesel at any percentage, and is being used in thousands of engines currently. Biodiesel is renewable solar fuel, grown and produced in the United States, and it reduces our dependence on foreign oil today.
