gehajake, check your Wally World and see if they have Murphy gas stations on site. They do down here, and they have a dedicated hose for non-ethanol. It's the only place I buy it because of exactly what you said.
Casey's has the same setup. More likely to have one closer to gehajake.
We don't have any Murphy's gas stations around here, three wally worlds but no gas station, and I havent been to or bought gas at a Caseys in a long time, I always thought they had the crappiest gas around, my old GMC with a carburated 454 in it would barely run on their gas, lifters would rattle and clatter something fierce so I just started avoiding the place, may have to revisit that option. Thanks for the heads up!
