    Great Product
    By  ARMANDO,  a  Verified Buyer  from  Apple Valley CA 92307  on  June 02, 2026
    This was my first time using Amsoil in my Lexus ES350, and I was impressed by how quiet and smooth my engine ran as I conducted a road test after changing the oil. I have always used Mobil One and decided to try Amsoil. Anyway, I am impressed so far, and if all goes well, I will use the same oil in my 2019 Lexus RX350
    Bottom Line
    Yes, I would recommend this to a friend.

    First time using "High Mileage" oil
    By  DAVE,  a  Verified Buyer  from  Near Austin TX  on  June 01, 2026
    I have a 2008 F150 with 160K and a 2014 Navigator with 130K on them. I've been using the Amsoil Signature on them in the past, but thought it would be time to try the High Milage oil at about the same price. I doubt I'll notice a difference but I'll sleep better at night.
    Bottom Line
    Yes, I would recommend this to a friend.

    Great Oil
    By  KEVIN,  a  Verified Buyer  on  May 15, 2026
    I have used Amsoil products over 40 years and have nothing but praise for their products. I gave my son in law a truck with 265k miles and he had his mechanic go through everything. The Engine compression test made the mechanic question if the engine was original because it showed minimal wear for the high mileage. The differential was quite and showed minimal wear. If you convert to Amsoil after the 1st 5k your engine will last a very long time & maintain its performance. I changed the differential after the 1st oil change also. Back in the aspirated carb days we used the foam regularly to keep it clean. We used to buy litte old lady cars and bring them back to life after a foam treatment. Kudos for making great stuff.
    Bottom Line
    Yes, I would recommend this to a friend.

    One of the Best Oils Available
    By  MIKE,  a  Verified Buyer  from  Tennessee  on  April 26, 2026
    Although there is no perfect oil for all applications, I believe AMSOIL is one of the very best oils available for normal consumer use. It is especially beneficial for turbo engines.

    Yes, I would recommend this to a friend.

    Only oil I use!
    By  CHUCK,  a  Verified Buyer  on  April 26, 2026
    AMSOIL is the only oil I have used in everything since 2008. Lawnmowers, Harleys, and all other vehicles. About 12 years ago I bought a 2003 Toyota Sequoia that had 145k miles. First thing I did was change the oil to AMSOIL and only changed the oil every 10k miles (also used AMSOIL filters). Over the 10k intervals I may have to add a quart between changes. It now has 450k miles and the motor has never been touched!
    Bottom Line
    Yes, I would recommend this to a friend.
