2 hrs a month seems a bit much, however
I put "Sta-Bil" in the tank on the last trip home for the season, and give it another dose after last fuel fill. (never store with out full fuel tanks, keeps condensation to a minimum) .
I run the gennie for 1 or 2 hrs after storing to insure that the Sta-Bil is run thru the gennie before winterizing.
then an hour every month, turning on the A/C and the microwave for the hour to insure that the gennie is working under a constant load.
