I too avoid ethanol gas at all cost as its the older vehicles carb seals and my cars run worse on it. Unfortunately I'm running out of places to get 93 octane as well. And the last couple years I've had terrible luck with watered down gas. There are only 3 gas stations within a 25 mile radius of me that sell non ethanol gas and none offer 93 octane, 1 kwik trip, 1 BP and 1 phillips 66. I've gotten in the practice of putting heet and octane booster everytime I fill up, it's stupid I have to do that. My friends and I all have issues with pinging with anything less then 93 octane, but all the 93 octane has ethanol around here and that wrecks'em. Just my experience.
