Top Tier standards say the fuel has 8-10% ethanol.

I will take a no-ethanol blend from a major fuel company, over a lower quality Top Tier product, any day.

That's true but not everybody lives close to one

When I use Sunoco I get about 300+ a tank but if I use golf I only get about 230

I see. Thanks JCL, that clarified my question. I usually use Costco because its convenient and cheap, but would really like to find a gas station with no ethanol.
