    Cmon. It's Amsoil. But....
    By  WAYNE,  a  Verified Buyer  on  March 22, 2025
    Amsoil is the best. We all know that. However, I'm disappointed that you guys don't know a Harley M8 takes more than 1 quart in the primary. On another note, I didn't get my free hat that I put in the code for.
    Bottom Line
    Yes, I would recommend this to a friend.
