At one time, the word "scooter" conjured up visions of underpowered, noisy, smoky, ill-handling bicycle-like machines. Although low featured single cylinder, air-cooled 50 to 150cc engines capable of reaching speeds of up to 35-40 mph. Today's scooters offer greatly improved handling and exceptional performance, while maintaining their affordability and excellent fuel efficiency. Their popularity has skyrocketed in recent years, and the scooter market is one of the fastest growing segments in the transportation industry. In fact, scooter sales increased 20 percent last year, with similar growth projected for 2007. Today's scooters range in size from 50 to 600+ cc's and utilize high-tech engine designs and advanced system controls. Some models are capable of obtaining road speeds in excess of 100 mph. Because these advancements place additional strain on the equipment, today's high-tech scooters demand high quality lubricants specifically formulated to address the special needs found in scooter applications: 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. Thermal stability - The operating temperatures of scooter engines fluctuate greatly, especially with air-cooled engines. Elevated temperatures cause the oil to quickly break down and shorten its service life. High temperatures also cause the oil to lose viscosity, minimizing its ability to control wear. Transmission and gear box compatibility - In many scooter applications, the engine and transmission and/or gear box share the same oil reservoir, exposing the oil to mechanical shearing forces and permanent viscosity loss as it passes through the contact areas within the gear sets. Wet-clutch compatibility - Some scooters utilize a frictional clutch to engage and disengage the engine from the drive train. In many cases, this clutch is immersed in the same oil used in the engine and transmission. Frictional compatibility must exist between the oil and the clutch to prevent excessive slippage and extend clutch life.

 New AMSOIL 10W-40 Formula 4-Stroke Synthetic Scooter Oil (ASO) is formulated specifically to meet the special needs of today's high-tech air- and water-cooled four stroke 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. AMSOIL 10W-40 Formula 4-Stroke Synthetic Scooter Oil is recommended for air- and water-cooled four-stroke motorized scooter engines calling for a 10W-40 viscosity, as well as transmissions and gear boxes calling for a 10W-40 motor oil, including Honda, Kawasaki, Suzuki, Yamaha, Vespa, Aprilia, Piaggio, Benelli, Vento, Kymco, Tank and TGB. It is recommended for the longest drain interval recommended by the equipment manufacturer.

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

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. 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) 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. Mixing AMSOIL 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 life expectancy and reduce the performance benefits. Aftermarket oil additives are not recommended for use with AMSOIL motor oils.
