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
AMSOIL Formula 4-Stroke Synthetic Scooter Oil is recommended
for use wherever SAE 10W-40 motor oil is specified in air-
and watercooled four-stroke motorized scooter engines,
transmissions and gear boxes that require the following:
- API SG, SL/CF
- JASO MA/MA2 (motorcycle wet clutch)
- ISO-L-EMA2
Engine manufacturers include, but are not
limited to, Honda, Kawasaki, Suzuki, Yamaha, Vespa, Aprilia,
Piaggio, Benelli, Vento, Kymco, Tank and TGB.
