    Good stuff
    By  BRYAN,  a  Verified Buyer  from  NY  on  May 18, 2024
    It's oil, seems to work well. First time using it so we'll see how it holds up. But it's Amsoil, so I'm pretty confident it will be fine.
    Bottom Line
    Yes, I would recommend this to a friend.

    Proof is in the pudding
    By  LARRY,  a  Verified Buyer  from  Texas  on  May 17, 2024
    Recently made some changes to my 532ci. BBF and was going to replace the rod bearings while having it apart. After 3 seasons of 200’ mud drag racing, the bearings still looked new. Ended up putting them back in and looking forward to another race season, thanks to Amsoil Dominator Racing oil!
    Bottom Line
    Yes, I would recommend this to a friend.

    Great for built engines!
    By  TRAVIS,  a  Verified Buyer  on  December 20, 2023
    This is all I’ll use! When you have thousands dumped into a high horsepower build with with very tight specs and tolerances, I come to AMSOIL for my oil needs. The high content of phosphorous and zinc also help protect the investment. Oil is crucial to any build, no sense in going with anything but the best!
    Bottom Line
    Yes, I would recommend this to a friend.
