I have been using 89 octane, 10% ethanol gasoline with the recommended dose of Sta-bil in my small engines for years. I never run the carborators dry for storage and the gas mixture sits in my generators for up to 12 months without any problems. That goes for my garden tractor, chainsaw, weed whacker, and generators. I do exercise my generators every couple of months though, and syphon out the old gas and put fresh gas in if I hadn't used a full tank of gas within a year. I use the old gas that was syphoned out in my pickup truck.
Been doing this for years without a single problem ever since non-ethanol blended gas was no longer an option anywhere in my area.
Edit: Until today, I never heard of TruFuel. I never had a need to search out fuel such as that.
