Re: Using E-85 as an octane booster...(mixing with E-85)
the 93 in which your car was tuned on had 10% ethel in it. So adding ethel into 92 wont give you the octane you need. Buy a 1 gallon fuel can with a locking cap or something and load that up with 100+ octane and just mix that in with the 92 and you will be fine.
