Fuel stabilizer is an acceptable alterna-
tive in minimizing the formation of fuel
gum deposits during storage. Add stabi-
lizer to gasoline in fuel tank or fuel stor-
age container. Follow the mix instructions
found on stabilizer container. Run engine
at least 5 minutes after adding stabilizer.
Craftsman 40:1, 2-cycle engine oil (air
cooled) is already blended with fuel
stabilizer. If you do not use this Sears
oil, you can add a fuel stabilizer to your
fuel tank.
