    I use Amsoil for every oil change in my 2022 CT5 Blackwing since I purchased the car. I even use Amsoil transmission & rear end fluid also. This oil is amazing and it's made here in the USA. Thank you Amsoil I will always use your products!

    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.
