AMSOIL Formula 4-Stroke® 100% Synthetic Scooter Oil

AMSOIL Formula 4-Stroke® Synthetic Scooter Oil is specifically formulated to meet the demanding needs of today's high-tech air- and water-cooled four-stroke motorized scooters. It provides unsurpassed wear protection and friction reduction for longer equipment life and cooler operating temperatures. The oil's exceptional shear stability ensures consistent viscosity protection, crucial in maintaining engine integrity under high RPM common in scooter applications. Its thermal stability resists breakdown in fluctuating temperatures, particularly vital for air-cooled engines. The oil also meets JASO MA/MA2 requirements, ensuring it is wet-clutch compatible for smooth clutch operation. This is especially important for scooters that use a wet clutch system. Moreover, it includes anti-corrosion additives for long-term protection during storage. AMSOIL Formula 4-Stroke® Synthetic Scooter Oil is recommended for scooters requiring SAE 10W-40 motor oil and meets API SG, SL/CF standards.

Formula 4-Stroke® 10W-40 Synthetic Scooter Oil

Outstanding Protection for Scooter Engines, Transmissions and Gearboxes

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 anticorrosion additive package provides long-term protection during periods of inactivity and storage.

AMSOIL Formula 4-Stroke® 10W-40 Synthetic Scooter Oil
  • Protects against wear
  • Resists shear for excellent gear protection
  • Delivers smooth clutch operation

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 out standing 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.

COMPATIBILITY

AMSOIL Formula 4-Stroke Synthetic Scooter Oil is compatible with other synthetic and conventional motor oils. Mixing AMSOIL motor oil with other oils, however, will shorten the oil’s life expectancy and reduce its performance benefits. AMSOIL does not support extended drain intervals where oils have been mixed.

Aftermarket oil additives are not recommended for use with AMSOIL synthetic motor oils.
