    Coating of engine parts
    By  JOHN,  a  Verified Buyer  from  Blue Ridge mountains  on  November 26, 2023
    One week ago and approximately 450 miles I installed a Fueling camchest. While removing the necessary parts felt the oil had lubricated these parts in such a way that their was no wear signs on any of the replacement parts. The last 4 oil changes where done with Amsoil and the bike has 25500 miles Highly recommend.
    Bottom Line
    Yes, I would recommend this to a friend.
