Formula 4-Stroke Synthetic 10W-40 Scooter Oil
Formula 4-Stroke Synthetic 10W-40 Scooter Oil
Outstanding Protection for Scooter Engines, Transmissions and Gearboxes Meets the needs of today's high-tech air- and water-cooled four-stroke motorized scooters. Unsurpassed wear protection and friction reduction for longer equipment life. Protects transmissions and gear boxes. Wet-clutch compatible to insure smooth clutch operation. Provides long-term protection during storage.
AMSOIL Formula 4-Stroke 10W-40 Synthetic Scooter Oil is formulated specifically to meet the special needs of today’s high-tech air- and water-cooled four-stroke motorized scooters, offering outstanding wear protection and friction reduction for longer equipment life and cooler operating temperatures. Its exceptional shear stability provides consistent viscosity protection and additional protection for transmissions and gearboxes, 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 rpm common to scooter applications increases 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 outstanding wear protection and extended equipment
life.
Thermal Stability
Scooter engine operating temperatures fluctuate greatly, especially in 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 gearbox
share the same oil reservoir. Formula 4-Stroke Synthetic Scooter Oil is shear
stable and resists thinning from mechanical activity, providing superior protection
for transmissions and gearboxes.
Wet Clutch Compatibility
Some scooters employ 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 is wet-clutch compatible. It contains no friction modifiers, 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 water-cooled four-stroke motorized scooter engines,
transmissions and gearboxes 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.
Service Life
Follow the equipment manufacturer's recommended
drain intervals.
Compatibility
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's life
expectancy and reduce its performance benefits.
Aftermarket oil additives are not recommended for use with AMSOIL motor oils.
