Customer Ratings & Reviews

I have been using this product and all your products for two decades and you have no equals in the market including the big boys. They are all a notch above everybody else. If you are having trans shifting problems run a batch of this before you rebuild or replace. Odds are you won’t need either of those options.

My Tundra crewmax 4x4 runs cooler while towing since amsoil transmission fluid was put in. Shifts amazing. Highly recommend this for any Toyota Tundra crewmax owner.

So far so good. The flexible bag was easy to handle and the Ams Oil videos were helpful.

Great ATF for replacing factory fluid. Smooth shifts and cooler temperatures.

The oil is great too, but man this container makes this task so much easier. Transfer cases are so fast to service with this container.

Bought a 2015 F150 had 150000 miles on fluid and bad vibration changed transmission fluid no vibrations just smooth shifts love this fluid great stuff

Worth the price for the performance you get.

Great product and I like the package for flexibility but taking off the seal brings out many expletives with it not coming off/one layer comes and not the other/have to stab it and peak it off in pieces. Take 5 min of R&D time to look at others and fix it. Please! Such a small thing hence 4 stars instead of 5

Here’s the deal folks, I’ve been using and promoting Amsoil Products since 1997. That said, I will continue to use them and nothing else! Now... That all said, and i am gonna be honest here Folks, I have measured my Miles Per Gallon on fuel consumption ⛽️ and I am Really sad to say, whether or not the Vehicle or Truck is New, Old, or in between, Hi milage or Low milage on the ODO. I have NOT measured or gotten not 1” further on Fuel. No big deal to me, I am using the products because I’ve torn down some small engines and some Big Block n Small Block’s and I’am here to Tell ya that the Wear on All of the Internals is Non Existent, and I mean down right Impressive! So, I suppose if people are getting some more MPG’S that’s great. Personally i am not seeing it at all. But on the other side of wear N Tear??? Absolutely remarkable!!! As far as the Tranny Fluid is concerned, I am in the process of Converting our 2018 Ford Edge 6F50 six speed Automatic over to Amsoil Fluid. It’s half again as Expensive as the FORD FLUID From Rock Auto ( including shipping ), But I believe it is a Far Better Fluid with better wear characteristics than the OEM which is made by Someone I’am certain. So, I’am a Loyal Amsoil Customer and User and Promoter of All Lube n Fuel n Gear Oil additives from Amsoil and will continue to be in the future. Biggest concern for me is the High Costs of the Amsoil Products.

Has my 60000 mile transmission shifting better than new!

I upgraded to a larger trans pan on a 5.0 F150 at 60k, Stock capacity was 14 quarts (3.2 gallons), upgraded pan 20 quarts (5 gallons) There is no significant measurable difference from Motorcraft to Amsoil at a consumer level, although the transmission "feels" (loosely using that term due to possibly being a placebo with new fluid" as it shifts smoother. I am pretty confident that the Amsoil will out perform stock ATF in longevity and wear protection.

Have used this ATF for most of the 220,000 miles on my van. Shifts and runs as new.

This is the good stuff, I put it in my 2016 Chevy Trax with 70'500 miles, And now it shifts like brand NEW!! Again! YOU CAN'T GO WRONG WITH AMSOIL!!

Great products and like the easy pour. But the seals are terrible to get off. They don’t peak off easily and you end up jabbing a screwdriver in them, tearing off the remaining part and hoping nothing got in the fluid. One time I didn’t notice that it separated and had a piece in the cap and tried to squeeze and it came out the sides, not fun. I’ve used both the trans oil and gear oil both had the same issue. Maybe R&D can spend 5 min looking at others seals and just copy it and then it’ll be great!
