    '21 Indian Roadmaster
    By  MITCH,  a  Verified Buyer  from  Mississippi  on  September 14, 2023
    I've been running this oil in my '21 Indian Roadmaster since new. Now at 42k miles and no problems at all. I can buy this oil, a high quality WIX oil filter, and get the copper crush washers in bulk cheaper than I can buy the semi-synthetic Indian oil kits for. Much better quality for the same cost.
    Bottom Line
    Yes, I would recommend this to a friend.

    Great oil
    By  KEITH,  a  Verified Buyer  on  September 12, 2023
    Just bought a used Harley that the previous owner used Harley Syn oil in. I immediately order Amsoil Syn motorcycle oil. Boy did it make a difference. Can’t wait to change the primary and transmission to Amsoil products!
    Bottom Line
    Yes, I would recommend this to a friend.
