    As they say at last call ... well lubricated
    By  EDMUND,  a  Verified Buyer  from  Canada  on  February 19, 2026
    Used Amsoil in my 2014 Harley. Rode that bike over 157,000 miles. Oil is the life blood of an engine ... Amsoil obviously goes the distance. I use Amsoil Metric in my 2 year old Royal Enfield SM 650 ... Superior product ... great engine protection.

    Great oil
    By  ANDREW,  a  Verified Buyer  from  Arkansas  on  February 12, 2026
    I run this oil in two Pan Americas. In my 2022 model when I bought it used it had 4500 miles on it, owned by a HD Master Tech. Always used HD 15w-50 oil. I changed oil in it as soon as o bought it, using Amsoil 15w-50 Metric Motorcycle oil. The magnetic drain plug was covered either fuzz when I drained the HD oil. After 3500 miles with the Amsoil, I changed the oil again and there was very very little fuzz. Just one spot on the mag was lug. With the Amsoil the bike starts quieter, no valve train rattle, shifts better, runs quieter. The other PA was purchased new 2024, nothing but Amsoil has been in it since new, never any fuzz on the drain plug, starts and runs quiet, shifts great, runs cool. Amsoil is the best protection policy for the drivetrain you can buy. Great stuff!!
    Bottom Line
    Yes, I would recommend this to a friend.

    BEST OIL EVER
    By  SCOTTIE,  a  Verified Buyer  from  LOUISIANA  on  December 17, 2025
    I was having a problem with my cam am spyder with a chirping noise, from a certain brand oil that is made for my bike. It created a chirping noise when throttling into 1st gear after oil change. I swapped the oil to AMSOIL METRIC and that was the best decision ever, Bike runs better than before. Now all I will ever run is AMSOIL in my bike my truck and my jeep. WONDERFUL PRODUCT.
    Bottom Line
    Yes, I would recommend this to a friend.

    The best oil period.
    By  TERRY,  a  Verified Buyer  from  Coarsegold, CA.  on  November 22, 2025
    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.
    Bottom Line
    Yes, I would recommend this to a friend.

    Exclusively used in my motorcycle
    By  THOMAS,  a  Verified Buyer  from  Mukwonago, Wisconsin  on  November 17, 2025
    I was fortunate to buy a brand new Honda VFR1200 DTC (actually my first new vehicle). After 50 break in miles with the oil that was in it I changed to Amsoil 10W-30 synthetic. That has been the only oil I use in this motorcycle. I also use Amsoil severe gear oil in the final drive. 47,000 miles and very happy with Amsoil products! Amsoil was highly recommended by mechanics and motorcycle industry people I know.
    Bottom Line
    Yes, I would recommend this to a friend.
