Rode out to the Eagle Mart by the Coast Guard base in Elizabeth City and bought 25.75 gallons of 93 octane non-ethanol gas yesterday. It was 4.34 a gallon. I'm gonna drain out all of the gas left in my tanks before filling with non-ethanol. I haven't had any trouble with my 170 I/O yet but dont want to later on either. The last time I took it out it had a little hesitation when throttling up, thinking it may be the old 10% ethanol gas. Anybody else changed over to non-ethanol gas and have you seen any difference in performance? Since I live close to Va. I looked there and found non- ethanol100 octane at the Suffolk Airport. Might have to get me some of that!
