MCF 10W-40 Synthetic Motorcycle Oil
High-Performance Lubricant for Engines and Transmissions
AMSOIL 10W-40 Synthetic Motorcycle Oil is a premium oil designed for those who demand the absolute best lubrication for their motorcycles. It is the result of extensive research and 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. AMSOIL 10W-40 Synthetic Motorcycle Oil is multi-functional and fulfills the requirements of both domestic and foreign motorcycles.
AMSOIL, the leader in synthetic lubrication, produced the world’s first API-qualified synthetic motor oil in 1972. Trust the extensive experience of AMSOIL, The First in Synthetics®, to do the best job protecting your motorcycle.
Reduces Friction, Heat and Wear
In high heat conditions, engine protection is not sacrificed with AMSOIL Synthetic Motorcycle Oil. It exceeds the standard for high-temperature film strength to deliver excellent wear protection (see graph) and contains a heavy treatment of anti-wear additives to reduce wear regardless of the operating conditions. AMSOIL 10W-40 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.
Provides Extreme-Pressure Quality Protection for Gears and Chains
With AMSOIL Synthetic Motorcycle Oil, there is no need for separate transmission or primary chaincase lubricants. It is absolutely shear stable and will not thin out from mechanical activity. AMSOIL 10W-40 Motorcycle Oil performs like a gear lube without the negative effects of extreme-pressure additives. In the FZG gear test, AMSOIL achieved a perfect score with a “zero” wear rating.
Delivers Superior Rust Protection
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 10W-40 Synthetic Motorcycle Oil contains special anti-rust agents. It passes the ASTM D1748 humidity cabinet rust test, demonstrating superior rust protection.
Provides Excellent Wet-Clutch Performance
AMSOIL 10W-40 Synthetic Motorcycle Oil contains no friction modifiers and promotes smooth shifting and positive clutch engagement. It is engineered to control heat and prevent slippage and glazing, helping improve clutch life, while meeting the wet-clutch frictional requirements of JASO Standard T903:2006, MA/MA2 and ISO-L-EMA2 of ISO Standard 24254:2007.

AMSOIL Synthetic 10W-40 Motorcycle Oil is recommended for liquid or air-cooled 4-stroke engines. It meets SAE 80W/90, API GL-1 gear oil requirements and is recommended for transmissions on both 4- and 2-stroke motorcycles. AMSOIL MCF is recommended for Honda®, Kawasaki®, Yamaha®, Suzuki®, BMW®, Husqvarna®, Victory® and other motorcycles where 10W-40 or 20W-40 engine oils or SAE 80W/90, GL-1 gear oils are used. Not recommended where an API GL-4 or GL-5 gear oil is required.
AMSOIL 10W-40 Synthetic Motorcycle Oil is compatible with other conventional and synthetic motor oils; however, mixing oils may 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 Oils.
For on-road use in engines and transmissions, change AMSOIL 10W-40 Synthetic Motorcycle Oil and AMSOIL Ea® Motorcycle Oil Filter at twice the motorcycle manufacturer-recommended change interval or one year, whichever comes first. Change other brand oil filters at standard intervals.
