What gas companies are NOT putting ethanol in their gasoline?

Question

What gasoline companies are not putting ethanol in their gas? I've noticed that every time I fill up my tank at stations that promote ethanol, I'm not getting as many miles per gallon.

This would be greatly helpful.

One simple fact that you might not know is that not all gas stations buy their own gasoline. They mix and match. For example the exxon next to your house might have the same gasoline as the sonoco or BP next door. As for as I know the only gas station that uses their own fuel is shell. Might be different in each state, but out here in east coast this is what I see.
