sounds good, going methanol with my engine. that shit is new to us.
Plain old distilled water (alone or as methanol mixture, injected at 1/10 of fuel volume) will help produce more boost/more spark advance => improve mileage/power without too much worry about aluminium and rubber parts, engine tune etc.
LPG has better energy than E85, is cheaper and does allow for more boost. Seems like ethanol fuel is only good if there's terrible shortage of traditional fuel
