Anytime you can stay away from ethanol gas, do it. It will deteriorate rubber lines if left sitting, plus the corrosion it leaves on fuel parts sucks. Around here we have 92 or 93 non-ethanol, is your highest octane 89?
89 is the highest non ethanol at the local places i maybe able to go more your way or towards Roanoke and find higher. I was thinking it was 91 but the other day I was pumping gas and noticed it was 89. The regular pump gas is 87,89,93 and NE was 89
