Probably 90% of gasoline today have 10% Ethanol. There is no significant amounts of Methanol in gasoline. California and Nevada do NOT require pumps to be labeled as dispensing gasoline with ethanol. Washington and Oregon do require pump labels. Refineries make gasoline base fuels at 84 octane and 89 or 90. The terminals blend in 10% ethanol to make 87 octane ULR out of the 84 octane. Similarly for the 91 super or 92 octane super in Wa & OR.

When you hear about premium gasoline without ethanol, ask yourself, where did the ONE station for miles get it? Is there a refinery nearby making 91/92 octane premium basestocks just for that ONE retail site? Not very likely! Think about the logistics of supplying one site, or even 4 sites, with a unique fuel. Was the price about the same? It would be relatively easy to supply a 87 octane fuel without ethanol. Almost impossible to make 91/92 premium without ethanol in today's environment. There are small pockets of the country without ethanol in gasoline, but they are VERY FEW.
