The Chevron 94 out west here also has 10% ethanol, so says the sign on the pumps.

depends on the station keith, most on the rez have ethanol but not where i buy mine. their premium and regular are ethanol free because they have float planes coming in to buy fuel. we tested their regular and it is indeed ethanol free.

ethanol has quite a negative impact on fuel mileage. i convinced my wife to start buying her gas where i do and she tells me that her rav4 picked up nearly a 1/4 tank in fuel economy.

Well, this thread has beautifully derailed. 
Ethanol has a higher octane rating than gasoline at 113, however it has only 80% of the energy of gasoline per unit volume.
As it takes a certain amount of energy to accelerate a vehicle, ethanol has less energy so that is why you use more fuel containing ethanol. (Although, ethanol based fuel at 10% would actually have only 2% less energy than a tank of pure gasoline). Anyway, the one great thing about ethanol, if you build a car that uses E85, you can boost the living crap out of it and make tons of power, it just uses more fuel is all.
