Running a diesel engine on Biodiesel versus filtered used cooking oil is a different story. Biodiesel requires a refining process and when burned doesn't smell like french fries. Biodiesel is made through a chemical process which converts oils and fats of natural origin into fatty acid methyl esters (FAME). Biodiesel IS NOT vegetable oil although it can be made from used vegetable cooking oil. It is also made from tallow and virgin crop oils. Any diesel engine can run on a blend of biodiesel (20%) and petroleum diesel (80%) known as B20 without modifications to the engine. Some diesel engines need no modification to run on up to 100% biodiesel (B100). Biodiesel cleans the engine, results in better gas milage, is currently produced in Hawaii, and is sold on Maui and Oahu for less than petroleum diesel.
