Whether riding aggressively, cruising or in stop-and-go traffic, AMSOIL 10W-40 Synthetic Metric Motorcycle Oil delivers the benefits most important to riders, including premium wear protection; smooth, confident shifts and cool, clean performance.

AMSOIL Synthetic Metric Motorcycle Oil is designed for metric bike owners who demand the absolute best lubrication for their motorcycles. 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, the leader in automotive 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 engine.

Reduces Friction, Heat and Wear
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.

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.

G3348 High Temperature High Viscosity

Delivers Superior Rust and Corrosion 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 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.

APPLICATIONS
AMSOIL 10W-40 Synthetic Metric Motorcycle Oil is engineered for motorcycles that require 10W-40 motorcycle oil, including those made by Honda, Yamaha, Kawasaki, Suzuki, Triumph, Can-Am and BMW.* Recommended for transmissions requiring an API GL-1 fluid. Not recommended where an API GL-4 or GL-5 gear oil is required.

SERVICE LIFE
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.

WARRANTY SECURE™
AMSOIL Synthetic Metric Motorcycle Oil is Warranty Secure, keeping your factory warranty intact. It is a high-performance replacement for vehicle manufacturer-branded products and is also backed by the AMSOIL Limited Warranty (G1363). For details, visit www.amsoil.com/warrantysecure.

I use this on my 2015 Yamaha FJR 1300. I've been using this since the second oil change and have had the oil tested at a lab for results. I now have 22k miles logged as of this review. The lab is impressed with the results and has recommended to extend the drain cycle as this oil is performing better than expected. I use Amsoil in all of my machines and the lab results prove that it's the best product for the money.

Best motorcycle oil ever with a side effect of better gas mileage on my bikes than any other Goldwing using any other oil. Only problem last order I ordered 10W- 40 Synthetic and got 10W-30. But no problem used it anyway. Keep up the great work.

Comments about 10W-40 Synthetic Metric Motorcycle Oil:

Been using this stuff 4 years exclusively since the price of Spectra went out of control. I have ridden and raced Yamaha's since 1964 and never had an oil leek with the exception of the oil seal on 650 twins clutch disengagement rod. This is a common problem with any oil, and it only ads 2 chain lubrication with an oily back rim. The problem I have been having is with the 650 Seca II clutch cover gasket they cant stop ANSOIL from seeping out after time.
