I was talking to a guy the other day about someone he knows has a contract with all the restaraunts in his area. He gets all there old french cooking oil and burns it in his truck for fuel instead of diesel. He gets it purified first but it sounds crazy to me. He said the exhaust just smells like french fries. I would think that it would gel up real easy. Anyone ever heard of this before its interesting.

 

Search for bio diesel. Keep you in reading for a couple of days.

 

Or weeks.

 

I talked to these guys a while back and they were working on a kit for the CUmmins. http://www.greasel.com/
