Veggie fuel converter for diesel engines

Folks at Greasecar.com have been in business for about 5 years now. They make a converter for diesel engines that can let your car run on used vegetable oil...Yes, things like used French Fry oil, Fried Clams, anything from the fryolator! Restaurants need to pay to have this used oil taken away, so they appreciate the opportunity to give their "trash" away. You can drive for nothing if you work it right!

You still run on diesel gas, but when the converter's sensor detects that the veggie oil is warm enough to run through your system, it kicks in.
