I live near Buffalo and there is a NOCO on route 5 not far from West Seneca that sells high octane 100% gas no alcohol. I know why, lake erie isn't far away so they are catering to the boaters. I buy that for my 1986 mercruiser engine and for all of my small engines, but it is pricey.
Now this probably doesn't help you or the rest of the country viewing this, but my point is that Noco sells it, and it shows the service station on their website as selling "E-FREE 93" gasoline, which means 100% gas and no ethanol. So for anybody looking for this you might find it on noco's website near you. I would think that looking for gas stations near large lakes would help. Boat owners with older engines, and that would be most of us, hate ethanol in gas. There are a lot of older fiberglass tanks and fuel lines that get eaten from the alcohol, which then gets turned into varnish or particles which then gets lodged or deposited in your carburetor. Yes a lot of boat engines are using carburetors, mine even has points and a condensor. Then you have the winter storage thing with gas sitting there for months, the ethanol absorbing any water that is in the air.
To the next person who will post I run ethanol in my engine with no problems, to each his own,
