www.pure-gas.org can help you find stations in the US and Canada with no ethanol. Some of them go up to 100 octane.

In my experience some of the listings are out of date, so YMMV.

I've tried it on road trips. I set my annual Christmas pilgrimage so that I was nearly dry at a real gas station by the TN GA border and tanked up on 96 no ethanol. For regular highway driving I didn't notice a change in mileage or operating characteristics. Perhaps if I had driven like a madman I would have noticed a difference. The comparison is with Costco 93 which is what I usually run.
