(I don't even look at the premium any more)
15% is pretty good mix. I don't think we get Gasohol down here but I'd gladly take 89 Gasohol. They probably cut out a lot of the isooctane and just use ethanol. Never looked into Gasohol really. Ethanol being around 110 octane rating and isooctane (2,2,4-trimethylpentane... yeah, I do have that memorized. Don't as me why... lol ) is 100. n-heptane is zero on the octane scale. Added benefit of E15 or any ethanol mix fuel is ethanol adds oxygen to the combustion. Helps give a more complete burn with less emissions of Carbon Monoxide, which is a product of an incomplete combustion. Carbon Dioxide being the product of a complete combustion of a hydrocarbon fuel (and DHMO
). Sry, that's enough chem. lol The only complaint I've heard from people is Gasohol contains less energy... but it's not that much less and gasoline engines aren't that effecient in the first place. Plus it supports the economy.

ChrisAdams, I have someone on another forum that has some questions regarding ethanol 85. I was going to e-mail you, but you don't have it available. Would it be possible for you to e-mail me your e-mail address so I can pass it on to him?
He certainly would appreciate it.
