Maybe E-85 is different, because from what I gather from posts here it's much cheaper than regular gas. But here in Iowa, I've never seen E-85, we have some 90 Octane gas that has an "Ethanol" sticker on it, so I dont know if's less ethanol or what. Either way, it costs about a nickel less than regular gas but the gas mileage is noticably poorer. Which means using it is silly, since the cost per mile is more than regular gas, and all it does is prop up farmers with huge government subsidies as opposed to forcing them to farm differently. Its a waste if you ask me, but no one person can likely know all the facts without having just as much bias.
What we really need are cars that run 100 mpg on a fuel made from politician corpses. Now that'd be a "win win" situation.
