Reviving this because
NC is on the list now.
I think the site is a great resource. Once you know where the station that sells ethanol free gas is, you know where to return to. I found one right here in my home town!
Also, I might be wrong, but I don't see how mixing non-ethanol gas in with ethanol gas could be an issue. The less ethanol the better so if you put some real fuel in there, how can that be a bad thing?
