    Amsoil 75/140 severe gear
    By  RANDY,  a  Verified Buyer  from  Florida   on  August 10, 2025
    Stinger Gear Box Co. recommends it in their gear boxes. I have a 640 hp. plus 150 shot of Nitrous in an Airboat. No problems and I wouldn’t run anything else. Highly recommend.
    Bottom Line
    Yes, I would recommend this to a friend.

    Track Car Use
    By  LAWRENCE,  a  Verified Buyer  from  Massachusetts  on  August 04, 2025
    This used in the 3.64 diff in my track car. It was recommended by the shop that built the diff. I change it every season and have been very happy with the performance of this weight fluid for my application.
    Bottom Line
    Yes, I would recommend this to a friend.

    Hard to find
    By  LAWRENCE,  a  Verified Buyer  from  Massachusetts  on  August 04, 2025
    75w85 is hard to find locally...in fact, pretty much impossible. Even Amsoil was out of stock when I first tried to order it. But this what my F-150 calls for in both the front and rear diffs. I waited until they had it back in stock. I trush Amsoil products to provide the quality and performance equal to or exceeding any other brand. I had just had the truck's transmission fluid and filter changed at a transmission shop (that is not a diy job) and now I've changed the front and rear diff fluid plus the transfer case fluid. (Thank goodness, that stuff was black when it came out!)
    Bottom Line
    Yes, I would recommend this to a friend.

    Excellent Gear Lubrication
    By  LEYDER,  a  Verified Buyer  from  Fishers, In.  on  August 03, 2025
    I have used Amsoil products in other vehicles, this is the first fluid change in my Jeep. The easy bag instead of a bottle made it so easy. Let's put pure synthetic to the test.
    Bottom Line
    Yes, I would recommend this to a friend.

    Mileage
    By  KELLY,  a  Verified Buyer  from  USA  on  August 03, 2025

    Worth the wait, for new Tundra
    By  Maverickjdh,  a  Verified Buyer  from  San Antonio   on  August 03, 2025
    This was out of stock for quite some time, but in the long run I was glad I waited the over a month to get it. The new Toyotas recommend doing this at 30 K depending on what the fluid looks like and after taking mine down it was definitely a good idea to do it at 30 K. So glad to be able to upgrade this hopefully much superior product because Toyota wanted way too much to do with this goodness gracious. Thanks again and oil also utilize the ATF for the transfer case and everything including install was absolutely flawless super easy with the squeeze bags. Also saves me a ton of money doing it myself and having somebody at Toyota do it who probably doesn’t really care nearly as much about whether they’re putting into it or how the service is done.
    Bottom Line
    Yes, I would recommend this to a friend.

    Just another awesome product
    By  BOBBY,  a  Verified Buyer  from  Hannibal Missouri  on  July 20, 2025
