STA-BIL Fogging Oil Spray (12 oz)

STA-BIL Fogging Oil is an aerosol petroleum treatment engineered to protect gasoline engines during off-season storage. Without protection, internal metal surfaces can begin rusting in as little as 30 days — fogging oil prevents that by forming a thin, persistent film on cylinder walls, pistons, and rings that ordinary motor oil cannot maintain as it drains away. The 12 oz can includes a nozzle extension straw for directing the spray precisely into spark plug holes or through the air intake while the engine is still running.

The two-step application process covers both methods: with the engine running, remove the air filter and spray into the air intake for 10 seconds, then shut the engine off, remove the spark plugs, and spray directly into each cylinder for 3 seconds via the extension tube. This dual-method approach ensures the combustion chamber, cylinder walls, and valve areas are fully coated. STA-BIL Fogging Oil is compatible with all 2-cycle and 4-cycle gasoline engines — outboard marine motors, ATVs, snowmobiles, motorcycles, chainsaws, snow blowers, and generators — and is safe for fuel injectors, catalytic converters, and oxygen sensors. It contains no silicone or PTFE.

For complete winterization, Gold Eagle recommends pairing fogging oil with a STA-BIL fuel stabilizer to treat the gasoline in the tank while this product protects the internal metal components. The aerosol can has a usable life of up to 8 years from purchase date.
