Ethanol in Premium Gas?
There is a difference between states on whether premium gas specifically has ethanol in it or not. Or, more correctly, whether it's required to have it in it. Two states in the Union, Missouri and Montana, have specific exemption to allow ethanol-free premium gasoline. So if you live in one of those two states, you can be thankful.
For the rest of us, we are faced with the unpleasant reality that the refineries are all but tied into putting ethanol in premium gas. This is because they have to use the ethanol to raise the octane level of their gasoline blend in order to satisfy the higher octane requirements of premium. This is one reason why you don't get better gas mileage with premium gas, because an essential part of that blend is a component that has less energy and forces the gas mileage down simply by nature.
So don't get fooled into thinking you can escape ethanol's grasp simply by paying more and getting premium gas.
I don't claim that all premium gas is ethnanol-free, I'm sure that varies by where you live. In my region of Wisconsin, Shell V Power (premium) is clearly marked on the pump as 100% gasoline with no ethanol added. YMMV and all that...

Yea thosevweren't my words, I just down loaded it from the company's website.
When I was in Minnesota a few weeks ago I was filling up at a gas station which was premium and 10 % ethanol for like $ 4.28 gal and a guy on a Harley and pulls up to a pump way in the back. Solo pump. When I went in to pay I asked why the guy was filling up back there and station attendant said he was filling up with non- oxygenated gas for $4.89 a gal. Normally used in mowers and boats he said.
