    Great in my Yamaha
    By  TIM,  a  Verified Buyer  from  Ontario  on  October 13, 2022
    Bought a used Yamaha Bruin over a decade ago. Changed all the oils to Amsoil when I got it. You could tell it was smoother and more responsive. Previous owner complained that it didn’t like to start in the cold. With the 0W-40 it fires right up even in -20 Celsius. Plowed snow with it for a decade now with no problems.
    Bottom Line
    Yes, I would recommend this to a friend.
