Just FYI to all the anti-ethanol people: the corn used for ethanol production is sold off as cattle feed, the same corn that would have otherwise just been sold as cattle feed in the first damn place. Ethanol is not a bad thing, it is not as corrosive as some would have you believe. in 10 and 15% levels, there is not enough content to do any damage, that is BS. E85 is 85% ethanol, now that stuff requires different types of hoses and pumps in your car, but that is it. Most new cars are compatible with it. On top of all that, I have done the research and testing myself- my van got 2-3 MPGs better when running ethanol over straight gas. I have verified this with several tests.
That is a physical impossibility. Ethanol contains less energy than gasoline. If you got better mileage then your driving habits and/or the driving conditions were better.
