    Mercury and Yamaha
    By  DANIEL,  a  Verified Buyer  from  Michigan   on  October 20, 2023
    Put this in my buddies Mercury 115 the last three years and it’s cleaning up what ever was in it when he bought it used. My Yamahas only see Amsoil gear oil and it looks good each year for the change before winter sets in
