Step 7:

Filling Lawn Mower With Fuel

Fill lawn mower with gasoline that has a Fuel Stabilizer added.

Gasoline goes stale in about 30 days which makes starting your engine more difficult if not impossible.

We recommend using only premium grade fuel in all your outdoor power equipment.  Lower octane fuel contains more ethanol which attracts moisture and causes carburetor failure.
