    Better than Expected
    By  Cambren,  a  Verified Buyer  from  FL  on  May 21, 2021

    Describe the issue

    I used this in my marine diesel engine. I had some reservations based on past experience with synthetic diesel oil from another manufacturer (noisy operation), but this far exceeded my expectations. Since switching from the industry standard mineral based oil to Amsoil Heavy Duty and Marine Diesel Oil, I have higher oil pressure and cooler operating temps, and the noise level seems lower as well. I am very satisfied.
    Bottom Line
    Yes, I would recommend this to a friend.

    01’ F250 7.3l Platinum Edition 400k miles
    By  RONNEY,  a  Verified Buyer  from  Texas  on  May 07, 2021

    Describe the issue

    Folks, I switched to Amsoil at 150,000 miles now I have 400,000 miles on my truck. I believe the quality of Amsoil and there filters are keeping the engine wear down. My last Blackstone oil sample (paraphrasing here) recommended I increase oil change intervals if desired because the sample indicates an engine of around 130,000 miles. I especially enjoy the the super quick delivery to my doorstep.
    Bottom Line
    Yes, I would recommend this to a friend.

    Describe the issue

    I changed the oil in my 2010 F 150 to Amsoil and the gas millage has increased by by 4 miles to the gal. I am very happy with the new oil and will keep a eye on the millage to see if it stays good
    Bottom Line
    Yes, I would recommend this to a friend.

    15/40marine diesel
    By  John,  a  Verified Buyer  from  Keremeos. Bc, Canada   on  January 29, 2021

    Describe the issue

    I have been using this engine oil in my Diesel Pusher Motor coach for 10 years and would not use another oil. I also have the Turbo Drive automatic oil in Allison Transmission and because this transmission is not only very good but it is an expensive one that I only want the best oil in it. I actually replaced the recommended Castrol Transynd oil that was in it to this Amsoil one and noticed that the shifting is smoother and the temperatures are lower during use. I monitor all the engine and transmission activity thru a computer while driving so I actually am seeing what is happening at any time, so, these issues I see and not only feel.
    Bottom Line
    Yes, I would recommend this to a friend.
