    Perfect motor oil for diesels.
    By  Cdub,  a  Verified Buyer  from  Nampa Idaho  on  October 21, 2022
    I have an ‘08 F-250 powerstroke. Truck loves Amsoil synthetics. I run Amsoil exclusively these days. My vehicles all run better on Amsoil. No joke. The preferred customer program and drop shipping to my front door makes running Amsoil very affordable. Great piece of mind knowing that my expensive truck has the best lubrication that money can buy.
    Bottom Line
    Yes, I would recommend this to a friend.

    By  MICHAEL,  a  Verified Buyer  from  Lancaster,SC  on  October 02, 2022
    I switched to Amsoil after Shell was not able to get the additive for their T5 Semi Synthetic oil. I'm glad I switched! I really Like this oil. I seem to be getting higher oil pressure and longer life with this oil. I have only been using it for about 6 months but I do like it a lot!
    Bottom Line
