Gas Mileage

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

I was told that the gas sold on the Indian reservations here in Southern Ontario have no ethanol in any of the gas grades. True or false, I don`t know. They sell their gas a fair bit cheaper than the rest of the gas stations in the area.

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.

I have heard that ESSO Premium is also ethanol free.
Anyone know for certain?

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.
