Adding Fuel Stabilizer to Your Power Generator Before Storage

If you plan to store your WEN generator with gas in the fuel tank, make sure to mix in some fuel stabilizer first. If this isn't done, then your generator may not start next time you go to use it, since the gas may degrade and gum up the carburetor. Fuel stabilizer helps prevent the carburetor from gumming up, and may help extend the life of your generator. For long-term storage, we always recommend to manually drain your carburetor to maximize the lifespan of your generator.

Adding fuel stabilizer is a straightforward process. Just follow these simple steps:

1) Add the correct amount of a properly formulated fuel stabilizer in the tank (if you aren't sure which brand to use, we recommend Sta-Bil 360). The recommended ratio for the majority of stabilizers is approximately 1-ounce of stabilizer per 2.5 gallons of fuel, but double check the recommendations on
your particular bottle.

2) Next, run the engine for about 5 to 10 minutes to allow the treated fuel to cycle through the engine and the carburetor. Follow the directions in your owner’s manual to shut down the generator.

After this, your generator will be ready for storage. If you neglected to do this in the past, you may need to clean or replace your carburetor to get your engine running properly again. For advice about this, check out our article How to Change Your Generator's Carburetor.
