PRODUCT DESCRIPTION
AMSOIL Formula 4-Stroke® 10W-40 Synthetic Scooter Oil (ASO) is
formulated specifically to meet the special needs of today’s
high-tech air- and water-cooled fourstroke motorized scooters,
offering unsurpassed wear protection and friction reduction for
longer equipment life and cooler operating temperatures. Its
exceptional shear stability ensures consistent viscosity
protection and provides additional protection for transmissions
and gear boxes, while its friction modifier-free formulation
ensures wet clutch compatibility and smooth clutch operation. A
special anti-corrosion additive package provides long-term
protection during periods of inactivity and storage.
Shear Stability
High engine rpms common to scooter applications increase shear,
causing conventional lubricants to lose viscosity and reduce
their ability to control wear, resulting in shorter engine life.
The synthetic formulation of Formula 4-Stroke Synthetic Scooter
Oil effectively resists shear, delivering consistent viscosity
protection for unsurpassed wear protection and extended
equipment life.
Thermal Stability
The operating temperatures of scooter engines fluctuate greatly,
especially with air-cooled engines. Formula 4-Stroke Synthetic
Scooter Oil resists breakdown at elevated temperatures,
maintaining its protective viscosity for maximum wear control.
Transmission and
Gear Box Compatibility
In many scooter applications, the engine and transmission and/or
gear box share the same oil reservoir. Formula 4-Stroke
Synthetic Scooter Oil is absolutely shear stable and will not
thin out from mechanical activity, providing superior protection
for transmissions and gear boxes.
Wet Clutch
Compatibility
Some scooters utilize a frictional clutch to engage and
disengage the engine from the drivetrain. In many cases, this
clutch is immersed in the same oil used in the engine and
transmission. Formula 4-Stroke Synthetic Scooter Oil contains no
friction modifiers and is wet clutch compatible, offering smooth
clutch operation and increased clutch life.
Rust and Corrosion
Protection
Scooters are often subjected to extended periods of inactivity
and storage, exposing the equipment to internal rust and
corrosion. Formula 4-Stroke Synthetic Scooter Oil is formulated
with a special anti-corrosion additive package designed to
provide long-term protection during periods of inactivity and
storage.
Applications and
Recommendations

Mixing AMSOIL
AMSOIL Formula 4-Stroke Synthetic Scooter Oil is compatible with
conventional and synthetic motor oils. Mixing AMSOIL motor oils
with other oils, however, will shorten the oil life expectancy
and reduce the performance benefits. Aftermarket oil additives
are not recommended for use with AMSOIL motor oils.
Health & Safety
This product is not expected to cause health concerns when used
for the intended application and according to the
recommendations in the Material Safety Data Sheet (MSDS). An
MSDS is available upon request at 715-392-7101 or on the
AMSOIL Website.
