I'm so glad that I have a station where I live that is non-ethanol. Pure gasoline. It costs 30 cents more per gallon than ethanol E10 fuel but Ill gladly pay the difference. The difference in mpg without ACES is 4mpg. I get 28 combined mpg using E10 fuel and 32 combined mpg in my 96 VW Jetta. I don't have to worry about the ethanol separating out of the fuel in the ground tank and destroying my car. This is also one of the reasons I'm switching to diesel vehicles in the future. No Ethanol in Diesel.
