Two- and four-stroke recreational vehicles, hand-held power equipment,
small engines and 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
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. Its all-position spray valve allows you to spray at any angle -
even upside-down. Consult equipment owners manual for application
AMSOIL Engine Fogging Oil applications include, but are not limited to, motorcycles,
snowmobiles, ATVs, outboard motors, stern drive and inboard marine engines,
personal watercraft, lawn equipment, chainsaws, snowblowers, portable generators,
hand-held power equipment, motor scooters, powered farm equipment, powered
construction equipment, cars and trucks.
