    Completed the fluid changes on the truck
    By  LAWRENCE,  a  Verified Buyer  from  Massachusetts  on  August 04, 2025
    I had just had the transmission service of flush and filter done. I then changed the fluids in the front and rear diffs and used this in the transfer case. Thank goodness I did. The fluid that drain out was black as coal. Now I can rest easy knowing the transfer case is running on fresh Amsoil fluid.
    Bottom Line
    Yes, I would recommend this to a friend.

    Worth every penny!
    By  TRAVIS,  a  Verified Buyer  from  Kansas  on  July 23, 2025
    I have been using Amsoil products for years now since a friend from work recommended them and got me started on trying the Severe Gear and Engine Oil. After really being happy with the Sever Gear and Oil results, especially the Metric Motorcycle Oil, I decided to start servicing my Hyundai SUV's with the Signature Fuel Efficient ATF. After many successful miles later I now put it in all of my transmissions. The latest being my 6L90, which are known for heat and reliability issues. Truck transmission shifts and operates very nicely even at the higher temps that these transmissions operate at. Fluid has held up very well, just like I would expect from an Amsoil product of any kind.
    Bottom Line
    Yes, I would recommend this to a friend.

    Packaging
    By  RANDAL,  a  Verified Buyer  on  July 16, 2025
    I ordered enough fluid to do a transmission service. I was disappointed that one of the quarts was leaking. You would think the soft containers would not be as susceptible to being popped open. With that aside the product (fluids)is top tier.
    Bottom Line
    Yes, I would recommend this to a friend.

    Right oil, easy to use
    By  GARY,  a  Verified Buyer  from  Roswell, NM  on  July 12, 2025
    After much searching to find the right fluid for my transfer case, I found Amsoil synthetic of the right grade. It was so easy to use, there just isn’t room to get a hard bottle higher than the fill hole.

    Do Not Exceed OEM recommendations
    By  JOSEPH,  a  Verified Buyer  from  CNY  on  June 25, 2025
    I know… warranty intact. But if the OEM says it failed due to the fluid, you may be out of a vehicle for months while everything plays out. Even if amsoil says it’s ok, do not go over OEM specs if under an extended warranty.
    Bottom Line
    Yes, I would recommend this to a friend.
