Formula
4-Stroke 10W-40 Synthetic Scooter Oil (ASO)
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.
