there is nothing that works as well as Amsoil. I’ve used it in cars, equipment, power sports boats. It make them run smoother longer wayyyyy longer than using store brand oils. I will always use Amsoil products in anything I can.
My first choice in oil
As a metric motorcycle mechanic, I use this oil almost exclusively. It performs exceptionally well and looks great after 5k miles. I really like the level of anti foam agent, it keeps the oil heavy even in hard riding, high RPM events.
Amsoil 10w40 Metric Motorcycle Oil
I use this oil in both Motorcycles and It's the best. Superior protection against thermal break down. I noticed that I gained a little bit of horsepower and the engine runs cooler even in 90°+ days in traffic. My Motorcycles never overheat.
The best oil period.
I’ve used Amsoil in my motorcycles for years with great results. They run cooler and shift smoother and best of all they last longer. Air cooled or water cooled, wet clutch or not, Amsoil is the best.
