I did some checking into state laws and the data has conflicts, but one list says WA, MT, OR, MN, MO, PA and LA require ethanol by law. Next, I went to that puregas site and found stations in those states saying they sold ethanol free gasoline. So this issue sounds like Qanon style bull. However, ethanol is supposedly banned in Maine. So if there are any Maineacs out there maybe they can clarify that.

Opinion on the benefits for modern cars are all over the map. I bought some at a station near me, but the sticker said "May contain up to 10% ethanol". They advertise as pure gas. I will check the data. If the fuel trim goes down and the timing advance goes up that means ethanol is regressive. However, ethanol is claimed as an octane booster so timing should retard, but it doesn't sound like that when I'm driving. It sounds like timing advanced. The data will out.

There are other claims about ethanol being an engine cleaner, but that may be crap
