    Only Oil I would use
    By  TimU,  a  Verified Buyer  from  Clinton Township, MI  on  November 02, 2022
    Over the years of owning my 2007 HD Ultra Classic, and after 70K miles, this is the only oil I have used. My bike came from the factory with HD oil, but at the first oil change, (500 miles), and every oil change thereafter I have used Amsoil. NEVER had an oiling problem. The current cylinder leak-down result is 6%. You can't complain about that after 70K miles.
    Bottom Line
    Yes, I would recommend this to a friend.

    20W40 V-Twin
    By  BRIAN,  a  Verified Buyer  from  Oklahoma  on  October 16, 2022
    Here in Oklahoma the summer heat can get pretty intense, like 105-109 degrees f. intense. My Thunderstroke 111 runs great with Amsoil in it and it quietens down the valve train too. I highly recommend Amzoil products for your motorcycle,I've been using Amsoil for over 25 years.
    Bottom Line
    Yes, I would recommend this to a friend.
