You might also stay away from ethanol, too. Stuff loves to eat rubber, nylon, gaskets and gas lines, needle tips, your pets, and has an affinity for water. Find yourself a station in the area that sells real gasoline. Buy a good performance additive, or tetraethyl lead from that guy in Georgia (if he still advertises it). Hard to find hi-performance high octane unleaded fuel at the pump any more - there used to be a couple of stations locally that sold Turbo Blue, but they are long since gone. I miss the smell of Holley aspirated 102 octane leaded gas - my eyes still water from the odor. Probably lost a few brain cells because of it, or maybe that was the other alcohol (non-ethanol).
