High-Performance Lubricant for Classic V-Twin Engines and Transmissions
AMSOIL SAE 60 Synthetic V-Twin Motorcycle Oil is a premium oil designed for those who demand the absolute best lubrication for their motorcycles. It features superior heat resistance and wear protection, is shear-stable and helps maintain proper oil pressure in elevated temperatures.
It stops viscosity breakdown, protects gears and chains, and meets SAE 140, API GL-1 gear oil requirements. It is multi-functional and fulfills the requirements of both domestic and foreign motorcycles.
Key Benefits
- Highest HTHS viscosity (7.6 cP) in the V-Twin lineup — over 2X the minimum standard
- Designed for classic Harley-Davidson Knucklehead, Panhead and Shovelhead engines
- Meets SAE 140, API GL-1 gear oil requirements
- Shear-stable — maintains proper oil pressure at elevated temperatures
- Excellent wet-clutch performance with no friction modifiers
- Superior rust protection for motorcycles in storage
- Lowest NOACK volatility (3.7%) among V-Twin engine oils for minimal oil consumption
- Warranty Secure — keeps factory warranty intact
Highest Film Strength in the V-Twin Lineup
AMSOIL SAE 60 Synthetic V-Twin Motorcycle Oil delivers exceptional high-temperature film strength with an HTHS viscosity of 7.6 cP — the highest in the V-Twin lineup and more than double the minimum allowable standard. It contains a heavy treatment of anti-wear additives and maximum levels of oxidation inhibitors.
It is shear-stable and will not thin out from mechanical activity. AMSOIL Synthetic V-Twin Motorcycle Oil performs like a gear lube without the negative effects of extreme-pressure additives, providing superior rust protection with special anti-rust agents that guard against storage, humidity and short-ride damage.
