TO PREVENT FUEL-RELATED PROBLEMS
1. Add Ethanol Shield
When adding a gasoline stabilizer, fill the fuel tank with fresh gasoline. If only
partially filled, air in the tank will promote fuel deterioration during storage. If
you keep a container of gasoline for refueling, be sure that it contains only
fresh gasoline.
