Customer Ratings & Reviews

I followed Don Smith’s YouTube video on how to properly flush a second gen. Tundra transmission using Amsoil. Time well spent. Excellent, even smoother shifting , all the time, with a drop in operating temperature. I now rest easy knowing that my transmission is protected by the very best!

Just started using more Amsoil products to service my 2014 Silverado after 91000+ miles. It was due by the looks of fluid that came out of it. Must say the Amsoil products look good and are very slick. Time will tell how well they perform over the long haul.

Best ATF I've ever used

My Jk 6 speed shifts so much better overall, and especially when cold, I can find 1st easily and it no longer pops out!

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!
