    Not always approved by Honda, SH grade is not SJ grade.
    By  ROBERT,  a  Verified Buyer  from  Maryland  on  July 30, 2025
    I bought a new 2025 Honda Goldwing and have used Amsoil in my other motorcycles. I bought this 10W30 for the Goldwing as that is what the Shop Manual calls for, but in SJ grade. I did not realize this Amsoil product was SH grade, so I do not want to void any warranty for the Goldwing. I don't know what the difference is between SH & SJ in the 10W30, but the 10W40 has an SN grade, but the Goldwing doesn't recommend 10W40. I usually run 10W40 in my other motorcycles. So I will maybe use this 10W30 in my other motorcycle?
    Bottom Line
    Yes, I would recommend this to a friend.

    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.

    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.

    Top quality protection
    By  SCOTT,  a  Verified Buyer  from  Minnesosta  on  June 15, 2025
    My BMW R1250RT loves this oil. Between scheduled services every 6,000 miles, this oil maintains itself and does not burn off. By contrast , the "factory" labeled oil does, needing 1 quart added in the same 6,000 mile timeframe.
    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.
