    Metric Motorcycle Synthetic
    By  JIM,  a  Verified Buyer  on  July 10, 2025
    I bought a new 2007 gold wing. After a few years I switched from Honda oil to Amsoil Metric synthetic and noticed better and smoother shifting on first oil change. Never looked back. Should have done it sooner.
    Bottom Line
    Yes, I would recommend this to a friend.

    The best oil for my motorbike.
    By  GILLES,  a  Verified Buyer  from  Port-Cartier, QC. Canada  on  June 30, 2025
    My ride, a Yamaha Venture Trans-Continental (1900) is running smoothly with this oil, the engine and the transmission. I used this kind of oil before, on Kawasaki Concours 14 and on Yamaha Roadliner. It's a very good oil and you may do a lot of kilometers ( more than the norm) with the same oil without any hassle. When the best product is available....you use it!!
    Bottom Line
    Yes, I would recommend this to a friend.

    AMSOIL 10W-40 synthetic Metric Motorcycle Oil
    By  JOHN G,  a  Verified Buyer  from  Webster, Texas  on  June 01, 2025
    This synthetic oil is great!! It provides much better lubrication for my 2018 Can-Am Spyder RT Limited SE-6 with the 1330cc ACE engine than the XPS stuff than the manufacturer suggests. After changing to this oil from the XPS garbage, my engine runs quieter, cooler, and shifts more gently. I will stick with this oil!!! Plus it's cheaper than the XPs stuff and I can order it directly.
    Bottom Line
    Yes, I would recommend this to a friend.

    Best oil for Powersports
    By  MATTHEW,  a  Verified Buyer  on  May 20, 2025
    I use this oil in all my Sportbikes and dirtbikes and have for 14 years. I wouldn't dream of using anything else in them. The motors run quiet the clutch performance flawless. No slipping when I change the oil there's no sediment in the oil from the clutch pads like you will see with other oils. This oil doesn't foam up like other oils do in the high rpm engines. The oil stays where the work is being done and keeps the parts lubricated throughout its lifecycle.
    Bottom Line
    Yes, I would recommend this to a friend.

    My first choice in oil
    By  Leo,  a  Verified Buyer  from  Coeur d'Alene, ID  on  May 19, 2025
    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.
    Bottom Line
    Yes, I would recommend this to a friend.

    Better than previous oil used
    By  grnblur,  a  Verified Buyer  from  SC  on  May 19, 2025
    I have been using Castrol Syntech for decades on all my motorcycles prior to them changing formulation. Since the cost of oils have gone up and Amsoil stays close to the same I gave it a try 4 oil changes ago on my street bike. It lasts longer than the previous oil is the fact that on a Concours 14 the transmission gets harder to shift when the oil starts breaking down. This oil lasts about 1500 miles longer before the transmission gets notchy.
    Bottom Line
    Yes, I would recommend this to a friend.

    best lubricants
    By  MICHAEL,  a  Verified Buyer  from  Dirty Jerz  on  May 10, 2025
    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.
    Bottom Line
    Yes, I would recommend this to a friend.
