For about $1500 you can convert your automobile to run on vegetable oil. There is a gentleman in Oberlin, Ohio, Stephen Merrett, that is saving a ton of money on gas by using recycled oil from restaurants. He has converted over 100 diesel cars and trucks. The Cleveland Plain Dealer reported that he also has a service station that offers the waste vegetable oil for $1.99 per gallon. Wow! There are several entertainers that have vehicles retrofitted for this as well. With oil prices at $100 a barrel and pump prices hovering over $3 a gallon this is something that justifies a closer look. He apprenticed under Ray Holan, author of a book on vegetable fueled cars. Ray's has a blog titled Autobloggreen.com.
