E85

RE: E85
E85 can only be used in a flex fuel car. It eats the seals in a standard fuel system and, I heard, requires slightly different engine fuel management. As with biodiesel I have seen damaged fuel systems caused by using fuel that the system was not designed to run.

RE: E85
I think it would be a pain in a non flex fuel computerized engine but I dont think it would be that big of a deal in a drag car setup, it is 105 to 110 octane and is the same cost per gallon as unleaded, I dont think the ethynol is as corrosive as methynol and it is present at a lower percentage in a lot of the gasoline at the present. As far as the diesel fuel goes I hear alot of people complaining about the reformulated diesel fuel coming on line in 2007 diesel owners will not have a choice but to run the new stuff or biodiesel so I am told.
