The Stabil naysayers are either FOS or simply haven’t used it themselves. It started as a simple experiment. I added 16oz of Marine formula Stabil to a full tank of fuel on my generator, and ran it through the carb. I always shut off the fuel cock and run the carb dry before storing. Every 6 months I would add about 6oz of Stabil, after running the generator for 5-20 minutes and then repeat draining the carb and storing.
Repeated this procedure just to see how long the fuel would last and run the generator under load without issues. This year is the 9th year and I’ve had to top off the tank once with about 3 gallons of fuel due to usage. Tank holds 7 gallons. Still starts on the 2nd pull, and will pull a load of 4500 watts without bogging or running rough. The fact that I have it stored in my basement which is temperature stable also helps, but Stabil absolutely works. This is regular pump gas BTW, not ethanol free.
