AMSOIL Engine Fogging Oil is designed to coat engine internals for long term corrosion resistance and the prevention of dry-starts. Suitable for any 2-cycle or 4-cycle engine (gasoline-powered only). Compatible with engines equipped with carburetors or fuel-injectors. For sale in USA only.
Why Fog an Engine?
There are two main reasons to use fogging oil in an engine. When engines are stored for the off-season or over long periods, swings in temperature and humidity levels can promote the formation of moisture on internal engine parts. This moisture can lead to the creation of rust and corrosion. Tiny rust formations can score pistons, cylinders and bearings during the next start-up
The second reason to fog an engine is to prevent dry-starts after long-term storage. Engine oil can eventually drain down from top-end parts leaving cylinder bores and overhead valve components without lubrication during the first critical seconds of start-up after long storage. AMSOIL Engine Fogging Oil clings to engine parts providing steadfast start-up protection after long layoffs.
When Should an Engine Be Fogged?
If an engine will not be started for a period longer than 8 weeks, a treatment of fogging oil would be a sensible practice. Use AMSOIL Engine Fogging Oil just as the engine is being shut down for the last time before storage. See directions for use below.
Engine damage can actually occur during periods when the engine is not running at all. AMSOIL Engine Fogging Oil can extend engine life and is part of a smart maintenance plan.
The One Thing You MUST Do Before Fogging an Engine
Yes fogging an engine is an essential part of engine storage maintenance, but an even more important step is making sure that the machine is store with fresh, stabilized gasoline in the tank. Storing a machine with stale gasoline (older than 4 to 6 weeks) or gasoline that does not contain stabilizer is an invitation for extreme fuel system deposits that could plug up carbs and injectors. Small engine repair shops make a living off of people that do not use fuel stabilizer. Gasoline stabilizer preserves fuel over extended periods which prevents fuel system deposits and ensures dependable starting and reliable performance when the machine is brought back into service. A premium additive like AMSOIL Gasoline Stabilizer is fundamental to proper engine storage maintenance.

Directions for Use of AMSOIL Engine Fogging Oil
We recommend two separate steps for fogging an engine. For most small engines, we recommend performing both of these steps for complete coverage.
Step One– Remove engine air cleaner, start engine and spray AMSOIL Engine Fogging Oil directly into the intake or carburetor until exhaust smoke is evident. Immediately shut down engine for the last time before storage.
Step Two– Remove spark plug and spray liberal dose of AMSOIL Engine Fogging Oil directly into cylinder. With the spark plug still removed, turn over engine multiple times for complete fogging oil distribution on cylinder bore and piston. Note that this step may not be practical for multi-cylinder engines in car, trucks and RV’s. It these cases, performing step one is sufficient.
