I saw a Ch--y duramax bio the other day and it was idling at a rest area, so I walked over to see what if any, was different. The exhaust was not as acrid by a long shot, and the power is supposed to be the same as petro diesel. I guess with the price of pump diesel going higher than mid-range gasoline, we may be better off to try it and like you say "help the farmers" out a bit.
