E0 is available at home and in Salina, KS so I don't mind the upcharge. When my mileage id good, the cost per mile is about a wash. Throttle response is much better as well.
My honest opinion...with modern vehicle fuel efficiency what it is, there is no rational reason for ethanol blended fuel. The tradeoff in cost to refine the ethanol is not cost effective. Sorry corn farmers, but we really can do better things with that corn.
Well it's a pointless debate now. Ethanol was mandated by Congress. Til the laws get changed, we're stuck with it. Your better MPG is just because ethanol has less BTU's per gallon than gasoline. It's about 114,000 btu's for gasoline and 76,100 for ethanol. There's just less energy per gallon in E10 than E0. However if you factor in the cost per btu, E0 is probably still more expensive than E10.
