Motorcylce Oil

Synthetic SAE 60 Motorcycle Oil

Synthetic SAE 60 Motorcycle Oil is a premium oil designed for those who demand the absolute best lubrication for their motorcycles. The result of extensive research, it is specially formulated to excel in all areas unique to motorcycles, including high engine RPM, wet-clutch lubrication and more.

10W-30 Advanced Synthetic Motorcycle Oil

AMSOIL Synthetic 10W-30 Motorcycle Oil is the result of extensive research, and it is specially formulated to excel in all areas unique to motorcycles, including high engine RPM, wet clutch lubrication, extreme pressure regions of gears and rust common to short drives and storage.

10W-40 Advanced Synthetic Motorcycle Oil

Advanced multi-functional formula for both domestic and foreign motorcycles. Recommended for high-performance liquid or air-cooled 4-stroke engines and transmissions and both 4- and 2-stroke motorcycles. Wet-clutch compatible. Not recommended where an API GL-4 or GL-5 gear oil is required.

20W-50 Advanced Synthetic Motorcycle Oil

Advanced multi-functional formula for both domestic and foreign motorcycles. Excellent in air-cooled motorcycle engines due to high heat resistance. Can be used in engines, transmissions and the primary chaincase. Not recommended where an API GL-4 or GL-5 gear oil is required.

AMSOIL Synthetic Motorcycle Oil Demonstrates Outstanding Protection in Extreme Heat

Protection against extreme heat is of the utmost importance in motorcycle applications. The aircooled V-twin engines used in Harley-Davidson motorcycles can get extremely hot, particularly when idling or traveling at low speeds. If a motorcycle oil cannot withstand hot operating temperatures, its ability to provide adequate engine protection is compromised. AMSOIL Synthetic Motorcycle Oil is formulated to withstand extreme heat conditions beyond the hottest temperatures motorcycles typically experience, providing peace of mind that motorcycles receive outstanding protection and performance no matter how extreme the operating conditions.
Dynamometer Testing To demonstrate its extreme-heat protection qualities, AMSOIL 20W-50 Synthetic Motorcycle Oil (MCV) was subjected to a dynamometer test designed to simulate conditions even more extreme than the demanding stop-and go driving conditions of a motorcycle rally or parade route.

A 2012 Harley-Davidson FXDB Dyna Street Bob motorcycle equipped with AMSOIL 20W-50 Synthetic Motorcycle Oil was operated for 68.5 minutes at low speeds, with
significant idle time broken by engine revving. Like most Harley-Davidson motorcycles, the Dyna Street Bob features an air-cooled V-twin engine, which relies on cooling fins arrayed along the cylinder walls to conduct heat away. To create the most-severe operating conditions possible, the electronic temperature controls, which safeguard the motorcycle when temperatures reach dangerous levels, were deactivated. The test subjected the oil and engine components to intense heat not normally experienced in the real world, with cylinder temperatures reaching more than 500°F. The extreme temperatures were no match for AMSOIL Synthetic Motorcycle Oil. After nearly 70 minutes of torturous testing and heat exposure, oil analysis revealed no change in oil viscosity and only minor levels of oxidation, TBN depletion and wear. Not only did AMSOIL Synthetic Motorcycle Oil prevent the engine from overheating and seizing, it did so without losing chemical integrity or ability to protect vulnerable engine components, demonstrating that it provides outstanding protection even in compromising and severe high-temperature riding and idling
conditions not experienced by most riders.

As temperatures climbed to more than 500 degrees F in the cylinders, an infrared camera revealed the red-hot conditions that assaulted the engine components and oil.
