    Noticed a difference at first start up
    By  Jim,  a  Verified Buyer  from  Mesa Arizona  on  November 08, 2023
    At the first start up after changing my oil to Amsoil, I immediately noticed how quiet my diesel motor is now. After driving on my first trip, I noticed the motor is running smoother than it did before, and I gained one mile per gallon. I plan on doing an oil analysis in the spring when I do another oil change. I will change both front and rear differentials next to Amsoil, and hope to see even more fuel savings. It was so convenient to order through Eben and my order was delivered to my front door within 2 days.
    Bottom Line
    Yes, I would recommend this to a friend.

    Excellent as always
    By  MITCHELL,  a  Verified Buyer  from  STX  on  July 03, 2023
    I have a 2019 Ram 3500 HO with 118k miles and was running Amsoil Signature Series 5w40 since break in. I was seeing oil consumption of 1-2 qts per 10000 miles. I swapped to Signature Series 10w30 and the consumption appears to have slowed way down. Time will tell but I'm very happy.
    Bottom Line
    Yes, I would recommend this to a friend.
