    Great product
    By  CAL,  a  Verified Buyer  from  Ontario, Canada   on  August 05, 2025
    I've been running Amsoil in all my bikes for the past 20+ years. My experience with each new motorcycle is that after the dealer oil is done and I start doing my own oil changes, draining the mfr oil and putting in full synthetic Amsoil, my bikes seem noticeably smoother on shifting, and I believe they run cooler as well. That and the benefit of increasing the oil change interval to stretch out maintenance, I feel that offsets the additional price point of the Amsoil. Also many of my previous bikes have not left the family after I brought a new bike into my garage, but have gone on to live another life with my son, or I've kept one as a secondary for me, so using Amsoil in my bikes is an investment in the longevity of my machines. 1988 Honda Shadow 1100 2002 Kawasaki Nomad 1500 2016 Kawasaki Voyager 1700 2022 Indian Roadmaster 116 Thunderstroke All still on the road and running strong.
    Bottom Line
    Yes, I would recommend this to a friend.
