For those of you into details, I found a neat little thing that tests how much Ethanol and junk is in gas. You add tap water, gas and Wala! It also will show anything else that isn't either. My local Casey's, where I get 91 (unless I'll hit a track), appears to have just under 10% Ethanol, which is the max. Look closely at the grey line.
