Star Brite Fogging Oil for Engine Storage | 1 Gallon | Part #084800 | Bulk Format for Marine Service & Multi-Engine Winterization
If you're winterizing a single engine once a year, a 12 oz. aerosol can gets the job done. If you're running a marina service bay, maintaining a fleet of rental boats, or servicing multiple engines each fall, the Star Brite #084800 fogging oil in a 1-gallon container is the economical, high-volume solution. The same protective formula that coats cylinder walls, piston rings, and valve surfaces with a corrosion-inhibiting film — in a bulk liquid format designed for use with a spray applicator, fogging wand, or direct intake application across multiple engines without running out mid-job.

Additional Information
Why 1-Gallon Bulk Fogging Oil Makes Sense for Service Operations:
A 12 oz. aerosol fogging oil can is convenient for a boat owner winterizing one engine — but it's an expensive and inefficient format for a marine technician or service facility winterizing dozens of engines per season. At $42.95 for a full gallon vs. $6–$12 per 12 oz. aerosol can, the 1-gallon format delivers significantly lower cost per engine serviced, with no wasted propellant and no mid-job can changes. Benefits for professional and multi-engine use:
- Lower cost per application — bulk liquid format is more economical per engine than individual aerosol cans at any service volume
- No propellant waste — liquid format delivers 100% product with no aerosol carrier gas; every drop goes into the engine
- Consistent application — use with a dedicated fogging wand or spray applicator for controlled, repeatable application across all cylinders
- Reduced service interruption — a 1-gallon supply handles multiple engines without stopping to swap cans
- Shelf stable — bulk liquid format stores efficiently between seasons without the pressure concerns of aerosol storage
How Fogging Oil Protects Marine Engines During Storage:
Fogging oil is applied to internal engine surfaces — cylinder walls, piston rings, valve stems, and combustion chambers — before shutdown for storage. The oil film does three things: it displaces moisture that would otherwise condense on bare metal during temperature cycling through the storage period; it neutralizes residual combustion acids that attack unprotected cylinder walls and ring lands; and it provides a lubricating layer that reduces dry-start wear on rings and cylinders during the critical first seconds after spring startup before oil pressure builds. Properly fogged engines come out of storage in significantly better condition than unfogged engines, particularly in humid climates or heated/cooled storage where condensation is a regular occurrence.
Frequently Asked Questions
1. How do I apply liquid fogging oil without an aerosol can?
Liquid fogging oil is typically applied using a dedicated fogging wand or hand-pump spray applicator inserted into the carburetor throat or air intake while the engine is running. Some technicians use a small battery-powered or hand-pump sprayer. The engine is run at idle, fogging oil is sprayed into the intake until the engine smokes and stumbles, then the engine is shut down. Consult your engine's service manual for the correct fogging procedure for your specific engine model.
2. How much fogging oil does each engine require?
A typical 4-cylinder inboard or sterndrive engine requires approximately 2–4 oz. of fogging oil per winterization treatment — applied until the engine stumbles and smokes at idle. A 1-gallon container provides enough product for 30–60 engine treatments depending on engine size and application method, making it well-suited for marina and fleet service operations.
3. Is this fogging oil compatible with 2-stroke outboard engines?
Star Brite fogging oil is formulated for marine gasoline engines. Verify compatibility with your specific 2-stroke engine before use — some 2-stroke engines have specific fogging oil requirements or procedures. For OEM-specified fogging products (such as BRP/Johnson/Evinrude), use the manufacturer-specified product when OEM compliance is required.
4. How should I store the remaining product between seasons?
Store the 1-gallon container in a cool, dry location away from heat sources and open flame. Keep the container tightly sealed between uses to prevent evaporation and contamination. Properly stored, fogging oil has a shelf life of several years — check the product label for the specific shelf life for this formulation.
