Today’s scooters are exciting, dynamic and sophisticated. AMSOIL recognizes this and has produced a synthetic oil that matches these attributes. AMSOIL Formula 4-Stroke 10W-40 Synthetic Scooter Oil is designed specifically for the unique operating challenges presented by today’s’ 4-stroke scooters.

Features and Benefits of AMSOIL Formula 4-Stroke 10W-40 Synthetic Scooter Oil

  • Reduces friction for improved power and enhanced wear control
  • Resists heat and viscosity loss
  • Ideal for any air or liquid-cooled 4-stroke scooter engine and transmission
  • Compatible and ideal for wet-clutches
  • Suitable for transmissions of 2-stroke scooters
  • Resists heat and viscosity loss
  • Contains powerful anti-rust/corrosion additives for off-season protection

Reduces Friction

AMSOIL 100% Synthetic 10W-40 Scooter Oil’s sophisticated formula reduces friction which improves operation on a number of fronts. First, the reduction in friction improves throttle response and maximizes engine output. Second, AMSOIL Scooter Oil reduces wear due to less friction between moving parts. Lastly, the reduced friction results in cooler operation in scooter engines.

Improved Scooter Shifting And Clutch Performance

AMSOIL Formula 4-Stroke 10W-40 Synthetic Scooter Oil improves much more than just engine performance. The reduced friction offered by this synthetic scooter oil results in dramatically improved gear shifting performance. The high film strength prevents metal-to-metal contact for long transmission life. This synthetic scooter oil is also 100% wet-clutch compatible and actually extends clutch life. This synthetic oil reduces transmission operating temperatures. The acid fighting additives keeps combustion by-products from degrading clutch plate material.

Combats Oil Consumption in Scooter Engines

Scooter engines tend to run at high RPM and with hot operating temperatures. AMSOIL Formula 4-Stroke 10W-40 Synthetic Scooter Oil is designed for exceptionally low volatility and high film strength. Therefore, it will not boil-off or breakdown during extended periods of high engine and transmission temperatures.

Rust Protection During Storage

The protection of your scooter doesn’t end when you store your scooter for extended periods. AMSOIL has added potent anti-rust and corrosion inhibitors to this scooter oil. This keeps engine and transmission internals free of damaging rust during long term storage.

Mixing AMSOIL Synthetic 10W-40 Scooter Oil with Other Brands

AMSOIL Formula 4-Stroke 10W-40 Synthetic Scooter Oil is compatible with all other brands of conventional, semi-synthetic and synthetic scooter engine/transmission oil. While you can safely mix AMSOIL Synthetic Oil with other brands, this will reduce the drain interval and performance capabilities of this product.

The use of any aftermarket oil additives is definitely NOT recommended.

Suitable Applications for AMSOIL Formula 4-Stroke 10W-40 Synthetic Scooter Oil

  • AMSOIL Synthetic 10W-40 Scooter Oil is suitable for air or liquid-cooled 4-stroke scooter engines and transmissions where a 10W-40 oil is suggested.
