its called E85 because it contains 85% ethanol and 15% gasoline. most gas stations will have fuel containing 10% ethonal or 15% ethanol, for cleaner emmisions. As far as I know, their are only a few stations that are E85, but they are for government vehicles only. I know i need to find a gas station that contains no ethanol. question is where are the stations containing 100% gas and no ethanol.
