I'm not looking to keep the small engine repair shop in business with frequent visits. I'm looking to keep my equipment running reliably over many years. When true trouble does strike, I will indeed then visit the shop and have a pro get me back on track.
But where do you find Ethanol-free 87 octane fuel? Locally they only sell Ethanol-free in 90 octane. I'll deal with the 90 octane instead of ethanol damage.
