Biodiesel is a type of diesel fuel created from organic sources, such as plant and animal fat. Biodiesel is considered a biofuel and can be used in existing vehicles without the need for an engine conversion.
Biodiesel is often blended with conventional diesel for use in cars and trucks. This type of fuel is cheaper than conventional diesel in some countries. In the United States, however, the price has fluctuated over the last decade.« Back to Glossary Index
