Well Im running my first tank of E100 Ethanol. Ive added a top end lube being its such a dry fuel. This is race quality at 117 octane and $1.54 per gallon. Will let everyone know how it works out. I am going to be replacing items soon anyway so it will burn E100 even though I intend on using a 50/50 blend rather then pure ethanol. So far things look good.
