    Best synthetic oil available for V-Twin engines
    By  HarleyH,  a  Verified Buyer  from  Meridian, MS  on  August 05, 2022
    In my opinion this is the best engine oil for my Harley Davidson Fatboy motorcycle. I have inspected some of the internals on my engine, and at 46K miles, there is very little wear indicated. I also use AMSOIL in my trucks engine. I highly recommend this synthetic engine oil to anyone who owns a motorcycle, especially an air cooled engine.
    Bottom Line
    Yes, I would recommend this to a friend.

    Only Amsoil for my Victory Motorcycles
    By  JOHN,  a  Verified Buyer  from  Central Minnesota  on  August 01, 2022
    I have had at least 1 Victory in my garage since 2001 and I have run Amsoil in all of them. Originally I ran the 20W-50 until this 20W-40 came out. Between my wife and I, since we both ride Victory's, I have had 5 Victory's running nothing but Amsoil since 2003. I still have 3 of those including a 2004 Vegas that actually has the lowest miles of the three I have, now that it doesn't go to rallies any more. Currently we run a pair of Visions and Amsoil is the only oil I trust to keep these bikes running smooth. And since they don't make these Victory's anymore I will keep running Amsoil so they will run as long as I will!
    Bottom Line
    Yes, I would recommend this to a friend.
