    Some if not the most expensive stuff out there
    By  Lubemeup,  a  Verified Buyer  from  MN  on  May 27, 2024
    If this is not the most expensive stuff then it is the most expensive there is! I will use mink oil next time! And I have been saying the thing for the last 20+ years. But this will be the year when I switch to mink oil I promise!

    As Advertised
    By  Vlads392Daytona,  a  Verified Buyer  from  California   on  May 27, 2024
    After watching multiple YouTube videos of Eben Rockmaker on AMSOIL ATF signature series. I was curious about how it would work on my 2018 Dodge charger 392 Daytona. I had a drain and fill done only using 4 quarts of ATF @ 30K miles and since then my transmission temps have decreased significantly and shifting is a breeze. Absolutely good stuff, I can feel the protection!
    Bottom Line
    Yes, I would recommend this to a friend.

    Great transmission fluid
    By  WESLEY,  a  Verified Buyer  on  May 26, 2024
    I have an older car and finding synthetic transmission fluid for it can be a challenge. Happened upon this stuff and tried it out. Night and day difference, feels like a newer car now. Quite pricey, but certainly worth the cost.
    Bottom Line
    Yes, I would recommend this to a friend.

    Transmission fluid
    By  WARREN,  a  Verified Buyer  on  May 22, 2024
    Been using Amsoil transmission fluid since 2016. Pull through mountains and flat lands with a 33’ camper, hot or cold weather. Transmission hasn’t had any issues. 2020 pull transmission to have refresh from years of heavy pulling through mountains. Tranny builder said parts look great. 5 years later replaced fuild first time since rebuild. Still smelt good. Stand behind the product.
    Bottom Line
    Yes, I would recommend this to a friend.

    Best ATF I’ve ever used
    By  Mike,  a  Verified Buyer  from  Tennessee   on  May 19, 2024
    I had the infamous transmission shudder on my 2018 duramax Colorado and I changed to the AMSOIL ATF fluid, the shudder is no more, and the transmission shifts so smoothly like its brand new. I am very impressed with this oil and will be using this in all my vehicles from here on out!
    Bottom Line
    Yes, I would recommend this to a friend.
