I don't think anybody specified ethanol or no ethanol. You should count yourself lucky you can even find non-ethanol gas. That stuff is like bigfoot in California. People say it exists, but I don't see it, so I don't believe it does! I just saw "93", and yeah, that stuff is easy to find over there. It just has ethanol. But really, I would assume that almost everyone here puts gas in their car with an ethanol additive since the "real stuff" is such a pain to find. But out here, we can't even get 93 WITH ethanol. We're stuck with 91 (with) for the most part.
Have you looked at this site ever?

There is a 92 over in Wausau. Don't know how accurate it is, but it might be worth a shot
