    E10 (10% ethanol) should not hurt your engine. You might notice a drop in MPG using E10 as 1 gallon of ehtanol does not provide as much energy as 1 gallon of gasoline.

    Oregon mandates an E10 blend for all grades of gas, statewide, and I heard they are contemplating rasing that to E15. Most cars should be able to run E15 with out any damage. Once you get above that though, one needs to have an engine and fuel system designed to work with ethanol.

    I was wondering about this subject awhile back a few months. But I have an Email from Both Sunoco and ExxonMobile stating that the fuel used in the winter and in high emissions or somg areas, and that the curant percentage is 10% and at that level there is no damage effect on any current engines. But if the level is raised to 15% or more then that changes a LOT of things. Engines built today are able to use 10% ethanol with no problem other than a slight drop in mpg, but if you raise that amount there are problems with the small metal ,rubbber and plastic components in your fuel system. But they both said that there is not any legislation that either company is aware of to increase the amount of Ethanol in Gasoline. But. . .

    I lose about 1.5 mpg in my Cadillac SRX with E10. I try not to use it.

    Gasoline with any percentage of alcohol will get less mileage because alcohol requires a more rich mixture to burn.

    RFG is required in any part of the country with air quality problems and, today, the oxygenate of choice is ethanol.

    Environmentalists and big-ag aim to keep it that way, too--inspite of, nowadays, RFGs being a solution looking for a problem.
