Kentucky Fried Car
A small but increasing number of people -- including some in the U.S. military -- are filling their cars with old grease from fast food joints. According to this Wired story, theyíre "running their diesel engines off either straight vegetable oil, known as SVO, or vegetable oil that has been converted to diesel fuel, or biodiesel." (They donít mention what effect a diet high in saturated fat might have on your transmission.)
