While getting zero ethanol 87 octane gas for my mower at my local Chevron today, I noticed a separate pump that I've never paid any attention to before. I thought maybe it was kerosene or something, but it turned out to be 93 octane no ethanol gas. It also had a big sticker on the pump that said "Not a Chevron product", so no idea who supplies it. I had no idea this type of fuel was available. Is this a fairly common fuel for areas that sell ethanol free gas, or is it somewhat rare?
