Octane rating aside, is it just the alchohol? Cooler burn?

I havent researched it enough to know the true answer.

Well, This thread has been pretty helpful so far, but, I think my fuel rail might be aluminum, and I will get that coated and possibly my intake manifold, but the head gets to suffer the wrath of corn booze.

BTW, does anyone know what kind of long term damage an aluminum piston will suffer? Maybe none since the fuel is burning in there?

I drove all summer and late last year on e85 mix and recently replaced my head gasket. Wisecos were fine, head did not look to be any worse for the wear and the fuel rail is fine.

It is my understanding that ethanol needs water to be present to really become corrosive to aluminum. Either way 7,000+ miles shows no detectable wear. I would be more concerned with the rubber fuel lines before the fuel rail.

partly yes, ethonal absorbs huge amounts of heat when it vaporizes.
