    Altitude JT
    By  ANGEL,  a  Verified Buyer  from  Florida   on  June 30, 2025
    Very happy with Amsoil since I made the first application I’ve been noticing that the engine is running more smoothly than before and the temperature in the engine has been very good even in a traffic jam in a hot weather like Florida weather I’m very happy with the outcome is a bit pricey at first but I don’t have to be doing an oil change every 3,000 miles instead I can make oil change every 6,000 with out breaking a sweat and I still be saving in extra oil service charges .
    Bottom Line
    Yes, I would recommend this to a friend.

    Gal Wasn't enough
    By  GILBERT,  a  Verified Buyer  from  TN  on  June 29, 2025
    I needed 5 quarts instead of 4 that come in the Gal product container. So I had to go to my local Advance to pick up a quart of Mobil1 to finish my oil change to top it off to get to the full mark on my stick.
    Bottom Line
    Yes, I would recommend this to a friend.

    What is there to say
    By  ROBERTO,  a  Verified Buyer  from  Texas  on  June 28, 2025
    Had to replace my engine on my 08 Silverado 2500 HD. This time decided to go with the BEST. Previously I had used Royal Purple. After doing my research AMSOIL is TOPS. Don’t think about it. If you truly want to take care of your vehicle then go with AMSOIL.
    Bottom Line
    Yes, I would recommend this to a friend.

    Terrific
    By  THOMAS,  a  Verified Buyer  from  Wisconsin Rapids  on  June 26, 2025
    I have been using this grade of oil for the last 17 years. It has been performing extremely well. I change the oil filter every 12,000 miles and the oil is changed every 24,000 miles. Between three vehicles, we have logged over 500,000 miles on this oil. It is a keeper.
    Bottom Line
    Yes, I would recommend this to a friend.

    great product
    By  RICH,  a  Verified Buyer  from  69130  on  June 26, 2025
    I have been using this product for over 10 years. I get 25,000 miles an oil change. Most of the time a year is up before I have made it to 25,000. Never had a single problem. Started using it in a 2003 Ford Excursion that was burning a quart every fill up, has not used any oil for 5 years now. Try it you won't go back to your former oil.
    Bottom Line
    Yes, I would recommend this to a friend.

    Best Oil There Is
    By  Broadcast Engineer,  a  Verified Buyer  from  Bristol, CT  on  June 24, 2025
    This is the oil my entire family uses. I have it in my 270k+ Corolla and my 1.8L engine is still rev happy and snappy. I drive 100+ miles a day, and I can tell you from experience, there is no other oil that could stand up to this kind of punishment.
    Bottom Line
    Yes, I would recommend this to a friend.

    By  STEPHEN,  a  Verified Buyer  on  June 24, 2025
    I have to 2019 Silverado and the amsoil cleared up the hard shifts and the torque converter shudder. It is now better than new. After having the motor replaced I was very worried about my transmission, I gave it a try and its nothing less than awesome. Thx.
