10W-30 100% Synthetic 4T Performance Motorcycle Oil

   10W-30 100% Synthetic 4T Performance Motorcycle Oil

Outstanding Lubrication – Reduces Heat and Wear
AMSOIL 4T Performance is formulated from high-quality synthetic base oils. Its smaller, more uniform molecules provide superior lubrication compared to conventional mineral oils. This results in better heat dissipation and a strong, heat-resistant oil film that offers excellent wear protection. It also maintains viscosity under high temperatures, helping to prevent power loss caused by thermal breakdown.

Confident Riding Experience
AMSOIL 4T Performance is designed for smooth gear shifting and reliable clutch performance in wet-clutch motorcycle engines. It helps manage heat within the gearbox, prevents clutch slippage and surface scoring, and extends clutch life—ensuring riders can enjoy confident and consistent performance.

Keeps the Engine Clean
Motorcycle engines operate at high RPMs and temperatures, making them prone to sludge and deposit buildup. These residues can reduce engine performance. AMSOIL 4T Performance contains high-quality detergents that help clean existing deposits and prevent future buildup. It also reduces sulfuric acid formation, keeping the engine running at peak performance.

Minimizes Oil Consumption
A primary cause of oil loss in motorcycle engines is evaporation at high temperatures. AMSOIL 4T Performance is engineered with very low volatility. Its NOACK volatility is only 5.6% (compared to more than 10% for typical conventional oils), ensuring significantly less oil burn-off and reducing the need for top-offs during operation.

Recommended Applications

AMSOIL 10W-30 4T Performance Synthetic Motorcycle Oil is ideal for a wide range of motorcycles—from small displacement bikes to big bikes—with air- or liquid-cooled engines that require 10W-30 viscosity. It is also suitable for transmissions requiring the following specifications:

• API SN, SM, SL, SJ, SH, SG

• JASO MA/MA2 (suitable for motorcycles with wet clutches)

Service Life

AMSOIL 10W-30 4T Performance should be changed based on the manufacturer’s recommendation, typically every 5,000–6,000 kilometers or every 6 months—whichever comes first.
