FUEL
Gasoline will oxidize and deteriorate in storage. Deteriorated gasoline will cause hard starting, and it
leaves gum deposits that clog the fuel system. If that gasoline in your engine deteriorates during storage,
you may need to have the carburetor and other fuel system components serviced or replaced.
The length of time that gasoline can be left in your fuel tank and carburetor without causing functional
problems will vary with factors such as gasoline blend, storage temperatures, and the amount of fuel in
the tank. The air in a partially filled fuel tank will promote fuel deterioration, as will very warm storage
temperatures. Fuel problems may occur in a few months or sooner if the gasoline was not fresh when the
tank was filled.
Adding a gasoline stabilizer that is formulated for this purpose can extend fuel storage life. Deterioration
problems can also be avoided by draining the fuel tank and carburetor prior to storage.
ADDING A GASOLINE STABILIZER
1. Fill the fuel tank with fresh gasoline. If the tank is only partially filled, air in the tank will promote
fuel deterioration during storage.
2. Add gasoline stabilizer. Ensure that the instructions for that product are followed.
3. Run the engine outdoors for 10 minutes to ensure that treated gasoline has replaced the
untreated gasoline in the carburetor.
4. Stop the engine.
DISPOSING OF ENGINE
If your engine has become damaged beyond repair, do not throw it out. Bring it to the
appropriate recycling facility.
