sage labeled IMPORTANT regarding
the use of gasohol in your engine.

native in minimizing the formation of
fuel gum deposits during storage. Add
stabilizer to the gasoline in the fuel
tank or fuel storage container. Follow
the mix instructions found on stabilizer
container. Run engine at least 5 min-
utes 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.
