Customer Ratings & Reviews

This is the first trams oil change in my 2017 GMC. It is used mostly for trailering. The trans shifts great and the temp is well within limits.

Flushed out the original fluid at 50K with Amsoil, shift quality is greatly improved. Car is tracked once a month and fluid is holding up well, had it tested by third party at 5000 miles and results were excellent!!!!

the best automatic transmission fluid out there. took care of my judder in my 2015 8 speed vette!

Changed the factory fluid out on a 2020 Kia Sorento with Amsoil full synthetic during test drive immediately noticed smoother shifting and no hesitation. I will change again at 15000 miles to get more of the old oil out . The Kia has a sealed transmission and I’m not a fan of flush and fill by auto shops and dealerships

Runs 15° cooler

Use it in my 2012 Dodge Ram 6.7 3500 tran seem to shift better Would recommend this product cheers Dave

I have been using Amsoil for years in my truck and cars. When my transmission went with only 57k I had to get a new one from Randy's Transmission, I asked them if I can run Amsoil in my new transmission, they actually recommend it, so I ordered 6 gallons to take care of it. Best choice I have ever made. Thank you Amsoil for providing me with awesome fluids to keep my truck running

Great product and a nice container that helps with input in tight places.

This also great product

A good application for heavy use offers better protection.

Did 3 Flushes and drain on my daughters 2008 Rav4 V6 Transmission and replaced differential and transfer case fluid. What a difference. Car shifts smoother and getting better mileage. Before it had a lag before shifting and that has gone away. This is the third time I have done this service, but the first time with Amsoil. If you are concerned about trying Amsoil in a Toyota don't be. We have had this car for 13 years and hope to keep it going with Amsoil. Bought enough to flush the 2017 4Runner which I will do this fall. Looking forward to see the improvements in performance to that vehicle. Also wondering if the mileage will improve on the 4runner.

Great oil

Best I can do for now is a four. The transfer case shifts smoother and more quickly. How it will perform over time .....no idea. Since it's an Amsoil product I suspect very well. But I can't state that until I see the results over time. You guys really should ask for a review after 6 months or so.

The best product I have ever used hands down!! Vehicle shifts better and runs cooler!!

Truck loves it, will always use it

So far so good, transmission seems to run smoother

Great product and I love the packaging. Made the installation fill a breeze. No pumps or hoses necessary !!! Thank you

Only 100 miles after the change, shifts seems to be firmer
