Amsoil ASOQT 10W-40 Formula 4-Synthetic Scooter Stroke Oil 1Q (946 mL)

Amsoil 1Q Formula ASOQT Synthetic 4-Stroke Scooter Oil (946 ml)

AMSOIL Formula 10W-40 Synthetic 4-Stroke Scooter Oil is specifically formulated to meet the special needs of today's high-tech air- and water-cooled four-stroke motorized scooters, offering excellent wear protection and friction reduction for longer equipment life and lower operating temperatures. Its exceptional shear stability provides consistent viscosity protection and added protection for transmissions and gearboxes, while its friction modifier-free formula ensures wet-clutch compatibility and smooth clutch operation. A special anti-corrosion additive package provides long-term protection during downtime and storage.

Shear stability

High engine rpm, common in scooter applications, increases shear, causing conventional lubricants to lose viscosity and reduce their ability to control wear, resulting in shorter engine life. The synthetic formula of Formula 4-Stroke Scooter Oil effectively resists shear, providing consistent viscosity protection for excellent wear protection and extended equipment life.

Thermal stability

Scooter engine operating temperatures fluctuate widely, especially in air-cooled engines. Formula 4-Stroke synthetic scooter oil resists breakdown at elevated temperatures and maintains its protective viscosity for maximum wear control.

Transmission and gearbox compatibility

In many scooter applications, the engine, transmission, and gearbox share the same oil reservoir. Formula 4-Stroke synthetic scooter oil is shear-stable and resists dilution from mechanical activity, providing superior protection for transmissions and gearboxes.

Wet clutch compatibility

Some scooters use a friction 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 compatible with wet clutches. It does not contain friction modifiers, providing smooth clutch operation and longer clutch life.

Protection against rust and corrosion

Scooters are often subject 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.

Compatibility

AMSOIL Formula 4-Stroke Synthetic Scooter Oil is compatible with other synthetic and conventional motor oils. However, mixing AMSOIL motor oil with other oils will shorten the oil's lifespan and reduce its performance benefits. AMSOIL does not support extended drain intervals when oils are mixed.

The use of aftermarket oil additives is not recommended with AMSOIL motor oils.
