Customer Ratings & Reviews

I use this for my 1st gen dodge. It keeps my automatic trans running cooler!

I will use no other trans oil my governor went out on my one ton diesel truck causing it to stay in third gear I drove it home fluid was brown and smelled bad changed the filter and fluid replaced governor and it runs great my friend with a 1/2 ton truck same part drove 8 miles had regular ATF entire transmission was toast. This synthetic stuff keeps lubricating when other fail saved me thousands.

I put in a bypass oil filter on the flagship Mercedes and used Amsoil oil, and every year I had it tested and they said, oil is good. Finally after 8 years I just decided to change the oil even though the lab kept saying it was good, and it was still transparent when I drained it. That says a lot about a perfect filter and a perfect oil in a great big engine.

This is the best oil I have ever used very happy

Wow! My transmission runs so smooth. Great results !

Great product, transmission runs very well

In my vehicle I not only gained fuel milage but it also shifts alot easyer.

T-56 shifts much smoother.

This stuff is great! So far, I have used it in a Dodge that requires ATF+4 (165k miles), a Ford motorhome that requires MERCON (42k miles), a Jeep that requires DEXRON (186k miles), and a Honda that requires DW-1 (169k miles). It was originally installed in all the vehicles over 10 years ago, and after all that time they are still going strong. I have done nothing to the transmissions except for periodic fluid changes. The fluid stays red and shift quality is great.

You can never go wrong with a perfect product Amsoil the best in the world I would recommend these products to anybody

I bought this to use in a hydraulic automotive lift. It works great.

I used this product in my power stearing system in work's great got rid of noise when starting in cold weather.

Purchased my Shelby with 3k miles on it and i could feel that the transmission was a bit notchy. So i decided to try Amsoil. Great product, i could immediately feel the difference. Great product

Motor oil, manual transmission fluid, engine coolant & differential fluid. When I bathe and install my new spider gears in Amsoil gear oil I will have an idea of the Amsoil improvements. My 4.6l runs better for sure, however, I am not finished improving yet.

I only use Amsoil fluids for my 2005 Mustang GT. I use the ATF for my 5 speed manual transmission and change the fluid about every 3 years or so ( plus use ATF for steering fluid). Shifts are always smooth even in cold weather and the dealership usually comments on how clean the old fluids are when they drain them out !

Works perfect

Did a pan drop on a Toyota at 60,000 and filled it up with this fluid. Drained and fluid it 3 to 4 time after every 200 so miles. I can say that the miles to the tank improved by 15+.

Used amsoil for many years and will continue to use it.

This is Amsoil's best product in my opinion. Have used it in so many Volvo's with nothing but success.
