For three to four months, Sta-Bil is best. Double the amount of Sta-Bil will double the life of your protection. Put the Sta-Bil in BEFORE you fill the tanks and then run the generator on the way to your destination to make sure that all of the fuel left sitting in the generator fuel lines will be protected.
