Fuel stabilizer is an acceptable alter-
native in minimizing the formation of
fuel gum deposits during storage. Add
stabilizer to the gasoline in the fuet
tank or fuel storage container. Follow
the mix instructions found on stabilizer
container. Run engine at least 3 min-
utes after adding stabilizer.

stabilizer. If you do not use this Sears
oit, you can add a fuet stabilizer to
your fuel tank.
