Engine Fogging Oil (FOG)
Offers superior film retention, providing long-term protection against corrosion and dry starts, extending
engine life and reducing operating expenses. Its aerosol spray formulation offers easy and clean applications,
while reaching more components and offering better distribution than straight motor oil.

Two- and four-stroke recreational vehicles, hand-held power equipment, small engines,
construction and farm equipment are commonly operated seasonally or infrequently, then stored for long periods of
time. During these periods of inactivity, and as a result of fluctuations in ambient temperatures, water vapor can
form condensate within the engine. When this condensate comes into direct contact with steel and iron components,
it forms surface corrosion on cylinder liners, piston rings, anti-friction bearings and steel/iron contact surfaces
on rotational seals. Long periods of storage can also dry out cylinders, often resulting in permanent damage when
the equipment is taken out of storage and dry started. In addition, fuel within stored equipment tends to oxidize
and form varnish and sludge deposits that clog injectors, fuel lines and carburetors, stick floats and cause poor
engine performance, starting problems, increased maintenance expenses and decreased equipment life.
Most two- and four-stroke motor oils are formulated to have an affinity to engine component
surfaces, acting as a barrier that keeps condensate from contacting engine components and forming corrosion.
However, the effectiveness of motor oil in this area diminishes with time.
AMSOIL Engine Fogging Oil (FOG) offers superior film retention, providing long-term protection
against corrosion and dry starts, extending engine life and reducing operating expenses. Its aerosol spray
formulation offers easy and clean applications, while reaching more components and offering complete distribution
of the oil, something especially beneficial in applications with horizontal cylinder orientation, such as outboard
motors. Consult equipment owners manual for application directions.
