    Highly recommended
    By  MILAN,  a  Verified Buyer  from  Brighton, MI  on  August 15, 2026
    I have found that every Amsoil product that I have used over the last few years has been superior to all I have used in the past! I have no doubt that this product will be equal in quality! I have been so impressed, with the performance of all products that I have used, that I have recently ordered all the products to replace the transmission, transfer case and differential lubricants in my 2021 Ford F150 4 x 4! I'm sure that you will be as equally impressed!
    Bottom Line
    Yes, I would recommend this to a friend.
