    1st Oil Change
    By  ROGER,  a  Verified Buyer  from  NJ  on  May 13, 2022
    Very easy to order online. I did have concern about the oil being acceptable in my Cummins 6.7L Diesel. CK4 but not Mopar MS 10902. The owners manual stipulates both. But Cummins CES 20081 is acceptable. I inquired Amsoil and they stated they will be changing the label in the oil to reflect its acceptable for this engine for 10W30. Great technical response!!
    Bottom Line
    Yes, I would recommend this to a friend.

    Nothing but the Best
    By  Cosbyman,  a  Verified Buyer  from  Cosby, TN  on  April 16, 2022
    The day I bought home my Massey Ferguson tractor I dumped the stock oil and refilled with Amzoil and a new filter. That was 8 years ago, and it still runs like a champ, and it burns less than 1/4 Qt. every year. I don't use anything but Amzoil , it's the best.
    Bottom Line
    Yes, I would recommend this to a friend.

    By  LOREN,  a  Verified Buyer  on  April 15, 2022
    My 2009 Ram 2500 had 180000 miles when I sold it. No blow by, like new compression , no engine problems using Amsoil. Buy a cheap vehicle and use cheap oil. I’ll buy the best for my Cummins engine.
    Bottom Line
    Yes, I would recommend this to a friend.

    Amazing Protection
    By  SEAN,  a  Verified Buyer  from  Texas  on  April 15, 2022
    I use Amsoil products in all of my vehicles air cooled and water cooled. I live in Texas and sometimes the operating temperatures are excruciating. Tests that I’ve seen with my own eyes prove that I am soil is far and away the best oil product on the market for battling friction and heat. I have a better peace of mind knowing that my vehicles are protected by Anzola products, and I love it when these vehicles are torn down for mods, they are clean and unharmed. Its a great product and well worth the cost.
    Bottom Line
    Yes, I would recommend this to a friend.
