- Outstanding wet-clutch performance
- Exceptional wear protection
- Promotes cooler operation
Reduces Friction, Heat and Wear
In high-heat conditions, engine protection is not sacrificed with AMSOIL SAE 60 Synthetic V-Twin Motorcycle Oil. It has exceptional high-temperature film strength and contains a heavy treatment of anti-wear additives to reduce wear regardless of operating conditions. Synthetic V-Twin Motorcycle Oil is thermally (heat) stable and contains maximum levels of oxidation-inhibitor additives. It is extremely resistant to breakdown and engineered to prevent damaging sludge and carbon deposits for superior engine cleanliness.
Extreme-Pressure Protection for Gears
With AMSOIL Synthetic V-Twin Motorcycle Oil, there is no need for a separate transmission lubricant. It is shear-stable and will not thin out from mechanical activity. SAE 60 Synthetic V-Twin Motorcycle Oil performs like a gear lube without the negative effects of extreme-pressure additives
Superior Rust Protection
Motorcycles are prone to rust from storage, humidity and short drives. Rust can cause major damage such as roller-bearing failure, wear, compression loss and blow-by. Good rust protection, however, comes by design and is not natural to engine oils. Unlike many motorcycle oils, AMSOIL Synthetic V-Twin Motorcycle Oil contains special anti-rust agents.
Excellent Wet-Clutch Performance
AMSOIL SAE 60 Synthetic V-Twin Motorcycle Oil contains no friction modifiers and promotes smooth shifting and positive clutch engagement. It controls heat and helps prevent slippage and glazing, while its high TBN helps improve clutch life by resisting acids that can degrade clutch material.
APPLICATIONS
Use in big-bore motorcycles that require SAE 60 motorcycle oil and any of the specifications listed below, including early model Harley-Davidsons* equipped with Knucklehead, Panhead* or Shovelhead engines. Use where SAE 90, API GL-1 gear oil is required.
- JASO MA/MA2
- API SL, SG/CF/CG-4
- ISO-L-EMA2
COMPATIBILITY
AMSOIL SAE 60 Synthetic V-Twin Motorcycle Oil is compatible with other synthetic and conventional motor oils. Mixing AMSOIL oils with other oils, however, will shorten the oil’s life expectancy and reduce its performance benefits. AMSOIL does not support extended drain intervals where oils have been mixed.
Aftermarket oil additives are not recommended for use with AMSOIL Synthetic Motorcycle Oil.
SERVICE LIFE
Recommended for use up to twice the motorcycle’s manufacturer-recommended change interval (miles/hours) or one year, whichever comes first, in engines and transmissions. For Big Twin* Harley-Davidson transmissions only, follow the Harley-Davidson recommended drain interval for synthetic oil of up to 20,000 miles or one year, whichever comes first. When using an engine filter other than an AMSOIL Ea® Motorcycle Oil Filter, change the filter at standard intervals.
For off-road use, change AMSOIL Synthetic Motorcycle Oil at the motorcycle’s manufacturer-recommended intervals.
Racing or modified engines are excluded from extended drain interval recommendations. Oil changes are at the owner’s discretion.
