I think my “local” (17 miles away) Sunoco station has 93E0 as well, and they also have E30 and “true” E85 (says “minimum 83% ethanol”) but both of those pumps also say they’re not Sunoco products. Considering this station is less than half a mile from a large Marathon transfer station, it’s a good bet it’s probably theirs.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?
