  • Contains robust anti-wear additives that further reduce wear in metal-to-metal contact regions, guarding against compression loss for maximum power and engine life.

EXCELLENT ANTI-RUST PERFORMANCE

    Great
    By  TIM,  a  Verified Buyer  from  Alabama  on  September 13, 2023
    Just did the 100 hr service on my new Yamaha VF90. I read and researched for weeks before deciding what brand oil to go with. I went 10w-40 because sometimes I’m running hard in +100° temps. From all the research I did on this oil, I have no doubt that it will fulfill my expectations.
    Bottom Line
    Yes, I would recommend this to a friend.

    Excellent product for you Seadoo.
    By  AUBREY,  a  Verified Buyer  from  Canada  on  July 31, 2023
    I have been using Amsoil in my Harley for year. I bought a seadoo this year and it was a no brainer for me to check the Amsoil site to see if they have an oil for it. They did not disappoint. Excellent product and highly recommend it. A friend of mine just bought a new seadoo. He called me up and ask about the first oil change. I told him to get the Amsoil. We did our oil changes together and love the product. Hands down the best decision you can make for your seadoo
    Bottom Line
    Yes, I would recommend this to a friend.

    Pefrect
    By  JEFF,  a  Verified Buyer  from  Florida Keys  on  July 09, 2023
    For the same price as conventional Yamalube, I'm running what has always been considered the gold standard of oils. My boat feels quicker, it *is* more fuel efficient, and after 50 hours it still looks brand new. I'm sold.
    Bottom Line
    Yes, I would recommend this to a friend.

    By  PHILLIP,  a  Verified Buyer  on  November 03, 2022
    Great oil, picked up an extra 2 mph on my Suzuki DF90. Synthetic is the way to go in outboards especially if you operate in saltwater. Motor was super quiet and ran smooth.
