Ethanol free isn't even an option near me and we are sitting near the source of much of the fuel production.

No need to step up to mid grade unless your engine is 10:1 or more compression and iron heads. Lead additives would be another waste of money.

Ethanol is really only a problem with fuel that sits for long periods. Absorbing humidity from the air the fuel can phase separate the water logged ethanol.
