Provides Superior Wear Protection and Extends Equipment Life
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 AMSOIL Formula 4-Stroke Full Synthetic 10w40 Scooter Oil effectively resists shear, delivering consistent viscosity protection for unsurpassed wear protection and extended equipment life.
Resists Breakdown in High Temperatures
The operating temperatures of scooter engines fluctuate greatly, especially with air-cooled engines. AMSOIL Formula 4-Stroke 10w40 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. AMSOIL Formula 4-Stroke 10w40 Scooter Oil is absolutely shear stable and will not thin out from mechanical activity, providing superior protection for transmissions and gear boxes.
Wet-Clutch Compatible – JASO MA, MA2 Oil
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. AMSOIL Formula 4-Stroke 10w40 Scooter Oil contains no friction modifiers and is wet-clutch compatible, offering smooth clutch operation and increased clutch life. AMSOIL 10w40 Scooter Oil meets the frictional requirements of JASO MA, MA2 and ISO-L-EMA2.
Protects Against Engine Rust and Corrosion
Scooters are often subjected to extended periods of inactivity and storage, exposing the equipment to engine rust and corrosion. AMSOIL Formula 4-Stroke 10w40 Scooter Oil is formulated with a special anti-corrosion additive package designed to provide long-term protection during periods of inactivity and storage.
Follow the equipment manufacturer’s recommended drain intervals.
