AMSOIL 10W-40 Synthetic Metric
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.
Whether riding aggressively, cruising or in stop-and-go traffic, AMSOIL Synthetic Metric Motorcycle Oil delivers the benefits most important to riders, including premium wear protection; smooth, confident shifts and cool, clean performance. With AMSOIL Synthetic Metric Motorcycle Oil, riders enjoy the confidence and security that comes with providing their bikes maximum protection and performance. It is Warranty Secure™ and will not void your motorcycle's warranty.
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.
In high heat conditions, AMSOIL Synthetic Metric Motorcycle Oil exceeds the standard for high-temperature film strength to deliver excellent wear protection. It keeps engines running cool by effectively reducing friction and heat, and it contains a heavy treatment of anti-wear additives to reduce wear regardless of operating conditions. AMSOIL Synthetic Metric Motorcycle Oil is thermally (heat) stable and contains maximum levels of
oxidation-inhibitor additives. It is extremely resistant to volatility and is engineered to prevent damaging sludge and carbon deposits for superior engine cleanliness.
• Premium wear protection
• Smooth, confident shifts
• Cool, clean performance
Smooth, Confident Shifts
AMSOIL Synthetic Metric 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, promoting longer clutch life.
Controls Foam
High-rpm operation causes some motor oils to foam. When foam bubbles travel between gear teeth or engine components, they collapse, allowing metal surfaces to contact, causing wear. AMSOIL Synthetic Metric Motorcycle Oil contains advanced anti-foam additives that help prevent foam, allowing riders to confidently push their bikes to the limit.
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).
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 motor oils. Unlike many motorcycle oils, AMSOIL Synthetic Metric Motorcycle Oil contains special anti-rust agents that deliver superior rust protection. With its high 11.1 total base number (TBN), AMSOIL Synthetic Metric Motorcycle Oil provides greater protection from acid corrosion and helps maintain internal engine cleanliness.
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.
AMSOIL Synthetic 10W-40 Motorcycle Oil is compatible with conventional and synthetic motor oils;
however, mixing oils may shorten the oil life expectancy and reduce the performance benefits. AMSOIL does not support extended drain intervals where oils have been mixed.
Aftermarket oil additives are not recommended for use with AMSOIL motorcycle oil.
Recommended for use up to twice the motorcycle manufacturer-recommended change interval (miles/hours) or one year, whichever comes first, in engines and transmissions.
When using an oil filter other than AMSOIL Ea® Motorcycle Oil Filter, change the filter at standard intervals. Racing or modified engines are excluded from extended drain interval recommendations; oil changes are at the owner's discretion.
This product is not expected to cause health concerns when used for the intended application and according to the recommendations in the Material Safety Data Sheet (MSDS).
