STA-BIL Fogging Oil Spray for Stored Engines — 12 oz Cans, 6-Pack, Long-Lasting Corrosion Protection

STA-BIL Fogging Oil is an aerosol engine preservative that sprays a protective oil film inside combustion chambers to prevent corrosion and ensure easier startups after storage.

When an engine sits unused, oil drains away from upper parts and moisture or condensation can corrode metal surfaces. STA-BIL Fogging Oil delivers a thin, clinging lubricant to cylinders, pistons, rings and other internal parts to displace moisture and reduce scuffing risk on restart. Packaged as a convenient 12 oz aerosol with a flip-up straw, this product is formulated for both two-cycle and four-cycle gasoline engines and is sold here in a six-can pack for seasonal or fleet storage needs.

How do I apply STA-BIL Fogging Oil for best protection?

Apply the fogging oil into the combustion chamber while the engine is off and cool, using the included flip-up sprayer or through spark plug holes to reach tight passages. Rotate the crankshaft by hand to distribute the coating if possible, and follow manufacturer storage guidelines for long-term protection.

• Spray directly into the combustion chamber or through spark plug holes.
• Use the flip-up straw to target valves, ports, and recesses.
• Turn the engine over manually to spread oil evenly across surfaces.
• Store engines in a dry, ventilated location after treatment.

Will this fogging oil work on my 2-stroke or 4-stroke engine?

Yes — STA-BIL Fogging Oil is formulated for both two-cycle and four-cycle gasoline engines. It creates a protective film on internal metal parts that helps prevent corrosion and minimizes wear when you restart after extended storage.

• Safe for lawn mowers, generators, marine outboards, motorcycles, snow blowers.
• Effective for carbureted and fuel-injected small engines when applied to combustion areas.
• Does not replace routine maintenance like oil changes or fuel stabilization.

How long does the protection last and how should I store the cans?

The product provides long-lasting interior protection while the engine remains dormant; for reliability, STA-BIL branded products are usable up to two years after opening when stored properly. Keep cans in a cool, dry place away from direct heat and tightly capped if not in use.

• Mark the open date on each can to track the two-year usable window.
• Store upright in a temperature-controlled area, away from flames.
• Replace cans showing damage, severe dents, or prolonged exposure to high heat.

Can fogging oil prevent startup damage after long storage?

Fogging oil reduces the chance of piston scuffing and cylinder wear by leaving a lubricating film where crankcase oil can’t reach while the engine is idle. It’s a preventative step that complements proper winterizing and maintenance routines to help engines start more smoothly after downtime.

• Coats cylinder walls, pistons, valves and rings to reduce dry-start friction.
• Displaces moisture that can cause rust and pitting on metal surfaces.
• Helps preserve compression and component integrity during storage.

Who is this for: STA-BIL Fogging Oil is designed for homeowners, seasonal equipment owners, marine operators and fleet managers who store gasoline engines for weeks or months. If you own lawn equipment, generators, outboards, motorcycles or any small engine that will sit idle, using this aerosol fogging oil before storage helps protect internal parts, reduce corrosion and improve restart reliability.
