You could, but like Shane said, knock resistance and cooling properties go down with less Ethanol, so you'd really have to be safely tuned at E85 to make it work. If you're constantly tuning by your wideband, it would work.

There's another thing that has come up when using E85, a lot more poo in the oil overflow tank. Looks like you have to change it very regularly. I think I'm going to route mine directly into the exhaust to take care of this.
