A mythbusters episode did a segment on a diesel which ran off of filtered vegtable oil without any modifactions to anything. They only had to filter the oil. We have engines out there that will run off any flamable liquid, the military uses them. but the thing is, gas is actually the cheapest flamable liquid out there anyway.

[nitpick]Liquid gasoline is not particularly flammable. Gasoline vapour, on the other hand, is very flammable.[/nitpick]
