STA-BIL Fogging Oil is an aerosol-propelled oil treatment designed to protect internal engine components during storage. This fogging oil can be sprayed to coat internal engine components and prevent corrosion. Formulated to displace moisture from metal to protect the engine, this product also lubricates the cylinder walls, pistons, and rings to prevent damage (scuffing) during start-up after prolonged engine storage. It is used in all two- and four-cycle gasoline engines. The STA-BIL Fogging Oil comes in a convenient 12-ounce aerosol can with a nozzle straw to direct oil into tight passages or through spark plug holes in the head and cylinder.
