10W-40 Advanced Synthetic Motorcycle Oil
API SG, SL/CF, CG-4; JASO MA/MA2; ISO-L-EMA2; API GL-1
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.
AMSOIL Synthetic 10W-40 Motorcycle Oil (MCF) is a premium oil designed for those who demand the absolute best lubrication for their motorcycles. AMSOIL MCF 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.
AMSOIL MCF is multi-functional and fulfills the requirements of both domestic and foreign motorcycles. It outperforms other conventional and synthetic motorcycle oils.
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 has the best high temperature film strength (see High Temperature Viscosity Protection graph below) of all oils tested and contains a heavy treatment of anti-wear additives to reduce wear regardless of the operating conditions (see Wear Comparison graph at right). 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
With AMSOIL Synthetic Motorcycle Oil, there is no need for separate transmission lubricants. It is absolutely shear stable and will not thin out from mechanical activity. AMSOIL MCF performs like a gear lube without the negative effects of extreme pressure additives. In the FZG gear test, AMSOIL MCF achieved a perfect score with a zero wear rating (see photo below).
Delivers Superior Rust Protection
Motorcycles are prone to rust from storage, humidity and short drives. Rust can cause major damage such as 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 MCF contains special anti-rust agents. It passes the ASTM D-1748 humidity cabinet rust test and clearly demonstrates superior rust protection (see photos below).
Provides Excellent Wet Clutch Performance
AMSOIL Synthetic 10W-40 Motorcycle Oil contains no friction modifiers and promotes smooth shifting and positive clutch engagement. AMSOIL MCF controls heat and prevents slippage and glazing, helping improve clutch life. AMSOIL Synthetic 10W-40 Motorcycle Oil meets the wet clutch frictional requirements of JASO Standard T903: 2006, MA/MA2 and ISO-L-EMA2 of ISO Standard 24254:2007.
