    20 Years
    By  SARKIS,  a  Verified Buyer  from  Los Angeles  on  July 14, 2026
    For 20 years I am using the Amsoil and will mot use anything else. I owned many (more than 20) different cars during these years and always used Amsoil. My mechanic wouldn’t believe I was really planning to change the oil every 10 or 25 k miles, but after changing it couple of times and seeing the condition of the used oil and my engine now he is not surprised anymore .
    Bottom Line
    Yes, I would recommend this to a friend.

    Best oil
    By  JP,  a  Verified Buyer  from  Colorado   on  June 28, 2026
    I only use Amsoil in all my cars. Even got a few others on board. The best hands down. I feel it’s protecting my engine parts and lubricating what it needs to.

    Correct application
    By  DENNIS,  a  Verified Buyer  from  14224  on  June 26, 2026
    Bought the oil change kit that included 5qts of oil and the oil filter for my 2022 VW Taos. Maybe Amsoil should go one step further and include a crush washer that is required for the drain bolt at every oil change to ensure no drips.
    Bottom Line
    Yes, I would recommend this to a friend.

    Best oil for Jeep Gladiator EcoDiesel
    By  DAVID,  a  Verified Buyer  from  Oklahoma  on  June 19, 2026
    This is the oil I'm using in my 23 Jeep Gladiator ecodiesel. I have almost 50k on the engine and recently had an analysis done after putting 5,900 miles on the oil. It came back saying: Metals are low next to universal averages, and those averages show typical wear for this type of engine after about 5,900 miles on the oil. These numbers show all is well with internal parts so feel free to add another 2K-3K miles to this oil.
    Bottom Line
    Yes, I would recommend this to a friend.

    Great oils
    By  ALFRED,  a  Verified Buyer  from  Plano, TX  on  June 16, 2026
    I have been trusting AMSOIL oils for years. I just had the Audi 3.0T engine internals inspected while doing some service, and the mechanic was surprised how clean it was at 130k miles.
    Bottom Line
    Yes, I would recommend this to a friend.

    #1 for Jeep/Ram EcoDiesel
    By  JUSTIN,  a  Verified Buyer  from  Calgary AB  on  June 02, 2026
    Comparing this 5W-40 to Pen Platinum euro and Mopar MaxPro, the Amsoil product has the engine running 3-5C cooler on the oil and 7-10C cooler on the coolant. I have not had any reduced power from high temps under long hills or heavy loads when using the Amsoil product.
    Bottom Line
    Yes, I would recommend this to a friend.

    Best oil ever
    By  FRED,  a  Verified Buyer  from  1744 Brown Shop RD.  on  May 24, 2026
    I’ve been using Amsoil since 1968 on dozens of autos, RVs, and tractors. I’ve run it in all of them with extended drain intervals and never had an oil-related problem. I’ll always stick with Amsoil for anything that needs oil.
    Bottom Line
    Yes, I would recommend this to a friend.

    Perfect for any VW group car.
    By  RANDY,  a  Verified Buyer  from  York, PA  on  May 13, 2026
    Used this oil for a service oil change on a 2022 Audi S4, these cars come with a turbo charged engine and Amsoil is the perfect oil for it as it goes above and beyond by protecting all of the internal parts of the engine while preventing heavy deposits from sticking.
    Bottom Line
    Yes, I would recommend this to a friend.

    By  Pat,  a  Verified Buyer  from  Virginia  on  May 11, 2026
    All great so far, Amsoil came highly recommend. I noticed an immediate reduction in engine noise. I put this in my newly rebuilt 642 Mercedes Turdo Deisel in a 2011 R350CDI. I do have a question though, my tech recommended making sure this Euro Spec Oil was for engines with a Deisel Particulate Filter system. Let me know about that, thank you.
    Bottom Line
    Yes, I would recommend this to a friend.
