The Stovebolt Site Forums The Shop Area General Truck Talk How long to keep gas?

I'm a believer in Sta-Bil, I stored a lawn tractor for unplanned 5 years, Sta-Bil was added to the tractor gas tank and circulated through the fuel system upon storage, machine was re-commissioned, started and continues to run to this day. Winter storage of our jet-ski's, mower, etc always includes Sta-Bil prior to shut down.
