Motor Oil Info

With AMSOIL Synthetic Motorcycle Oil, there is no need for a separate transmission lubricant. It is shear-stable and will not thin out from mechanical activity. AMSOIL SAE 60 Motorcycle Oil performs like a gear lube without the negative effects of extreme-pressure additives.

Motorcycles are prone to rust from storage, humidity and short drives. Rust can cause major damage such as roller bearing failure, uncontrolled 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 Motorcycle Oil contains special anti-rust agents.

In high heat conditions, engine protection is not sacrificed with AMSOIL Synthetic Motorcycle Oil. It has exceptional high-temperature film strength, contains a heavy treatment of anti-wear additives to reduce wear regardless of operating conditions and helps maintain oil pressure in extreme heat conditions.

AMSOIL SAE60 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.

Many Harleys with older engines and some big-bore bikes require a 60-weight oil. While AMSOIL SAE 60 Super Heavy Weight Synthetic Racing Oil (AHR) provides more than adequate performance in these applications, it is not formulated to address the issues specific to motorcycles. In order to better address these issues, AMSOIL now offers Synthetic SAE60 High  Performance Motorcycle Oil (MCS).

AMSOIL Synthetic SAE 60 motorcycle Oil is formulated specifically for motorcycles using the same proven technology developed for AMSOIL 10w-30, 10w-40 and 20w-50 motorcycle oils. AMSOIL SAE60 Motorcycle Oil is multi-functional and delivers premium performance in motorcycle engines and transmissions.

AMSOIL synthetic motorcycle oils were introduced as premium oils designed for those who demand the absolute best lubrication for their motorcycles. The results of extensive research, they are specially formulated to excel in all areas unique to motorcycles, including the high temperatures of air-cooled engines (such as Harley-Davidson V-Twins), wet-clutch lubrication, extreme-pressure regions of gears and chains and rust common to short trips and storage.

These multi-functional oils lived up to the hype and AMSOIL proved it by publishing the most thorough study of motorcycle oils ever produced. As more motorcyclists spread the word about the performance benefits of AMSOIL synthetic motorcycle oils, the demand for a complete line of motorcycle lubrication products increased.

Bikers experience first-hand the mechanical stress their motorcycles endure. Modern bikes demand lubricants that protect against high internal engine heat, maintain film strength on gears under extreme pressure and guard against rust formation during storage. Motorcycles rev high and run hot, and lubrication failure could result in consequences for both vehicles and passengers. In addition, motorcyclists invest a great deal of time and money into their bikes, and they demand products that provide the best performance and protection for their investments.

AMSOIL Synthetic Motorcycle Oils deliver maximum viscosity protection for hot-running American and foreign motorcycle engines, transmissions and chain cases. Their exclusive synthetic formulations effectively reduce friction and heat, keeping bikes running cooler and minimizing oil consumption.
