    Best Oil for my Motorcycles
    By  MARC,  a  Verified Buyer  from  Pierrefonds QC  on  November 28, 2022
    I use it in my air-cooled R1200ST BMW and despite some stop-and-go riding in hot weather that sends the temperature gauge into the red, the oil has maintained its properties after a rough season. It goes in all my modern bikes.
    Bottom Line
    Yes, I would recommend this to a friend.

    Another reason to love AMSOIL
    By  RT,  a  Verified Buyer  from  San Simon, AZ  on  October 31, 2022
    I bought a new Suzuki GS750 motorcycle in 1979. I still have it today, in like-new condition, with more than 55,000 miles on the odometer. This model didn't have a dipstick to check the oil level. Instead, it had a small round window in the right case cover, for easy viewing. At a glance you could see the oil level. Very convenient! Over time this window became clouded over, preventing me from detecting what the oil level was. That was rather annoying. Unfortunately, I was never able to find a replacement window. Not to worry, I thought, as the bike never used any oil between changes. One of those changes was to AMSOIL. (In 1979 I didn't know about AMSOIL or if there was such a thing at that time.) To my great surprise, after switching to AMSOIL 10W-30 Metric Motorcycle Oil, and putting on a few miles, that viewing window became clear! WOW! I couldn't believe it. AMSOIL cleaned the gunk off that viewing port. The oil level was now clearly visible, for the first time in years. One can only imagine what cleaning power it has on the rest of the engine! The only question is, Why would anyone use any brand of oil other than AMSOIL? Thus far I've found no satisfactory answer.
    Bottom Line
    Yes, I would recommend this to a friend.

    METRIC Motorcycle Oil
    By  BRIAN,  a  Verified Buyer  from  Chilliwack BC  on  October 02, 2022
    I ride a 2014 Honda CRF250L 70% dirt,30% street. Previously used the Hondaline Synthetic thinking it was best available.Decided to try the Amsoil 10/40 , shocking difference from first start after oil and filter change. Smoother clutch action and shifting as well as knowing the Amsoil reputation for internal engine protection.My oil of choice from now on!
    Bottom Line
    Yes, I would recommend this to a friend.
