Fuel stabilizer protects the gas. Fogging oil protects the engine itself. STA-BIL Fogging Oil sprays a coat of oil onto internal engine parts before a long layup, pushing moisture off the metal so it doesn’t corrode while it sits.
It also lubricates the cylinder walls, pistons and rings, which helps prevent scuffing when you start the engine again after months of storage.
How STA-BIL says to use it
Start the engine and remove the air filter.
Spray fogging oil into the air intake of the running engine.
Shut the engine off after 10 seconds.
Remove the spark plugs. Attach the extension straw and spray into each cylinder for 3 seconds.
Put the spark plugs back in.
It’s for all 2-cycle and 4-cycle gasoline engines, including outboard, marine, small engine and automotive. 12 oz aerosol with a straw for tight spots and spark plug holes. Made in the USA.
Fair warning: getting to the air intake with the engine running is easy on some bikes and a real job on others. Check your service manual before you fog a motorcycle, especially a fuel-injected one. Pair it with STA-BIL Storage in the tank and our motorcycle storage guide for the rest.
