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.
