Customer Ratings & Reviews

It's great to be a member of Amsoil for over a year to support the company with there products. I use all there products and they have not let me down. The ride is smooth and performs. Just recently did a transmission service on my car that has over 173,000 and still running strong. Definitely recommend Synthetic OE ATF.

Changed the transmission oil in my Cruze and the transmission shifts a lot smoother. Kinda wish it came with a sticker to throw on the Cruze, but defiantly not a deal breaker on using their products!

I own a 2017 Chev Express 3500 4x4 with the 6L90 transmission with 31,000 km. I did a complete transmission fluid flush and fill at 27,000 km and used this product. Within the first week of driving I noticed much smoother transmission shifts, quieter shifting and lower fluid temps (I run a transmission temp gauge). I found this surprising and delightful because there was only 27,000 km on the factory GM transmission fluid. Great product. Excellent performance. Can't ask for much more than what I have experienced.

Used this in Chevy transfer case, changed at 30k the old fluid was nasty for such low mileage. With amsoil, shifting has become quieter and smoother so far I'm liking the product.

Used it in a new install of a 1990 ford 1 ton transmission. Got the job done!

Used exclusively in all my Cummins diesel trucks. 300,000+ miles on them. One just recently had transmission rebuilt only for OD issue, and other has never been opened up. Superior performance in the high desert heat where I live, and long service intervals between changes. Always stays red!

Drain and fill on my 13 volvo s60 t5. Slight improvement on gear changes.

Put this in my T case. Old oil was past do. This fluid got rid of some noise in the cabin. Works good. I'll see how it holds up this winter when I use 4x4 the most.

I bought this product to use in my transfer case in a truck with 300000 km so that I can keep on driving it indefinately and know it has the best protection.

Amsoil products work great! The tranny shifts smoother.

Used this on my 2015 Ford Explorer and it'a working great ! 92,000 and going

I use this product in my 2005 Jeep LJ and have had no issues just smooth transfer in the transfer case.

Car works different

Cool thanks

Use in my daily drainer and it's great

After changing the fluid and filter, the truck runs just like new. Could not be happier

Lovin' it! We'll see how it does over the long haul, but had numerous transmission shift fault codes, neither led myself or a more experience gearhead to believe the tranny in my Chevy 2500 HD was failing, just had some intermittent quirks. With that, I made the shift to AMSOIL when it was decided upon to change the tranny fuel, especially not knowing if the reseller business had performed the task since the Chevy was nearing 50k miles. Went with a deep pan and filter, added LOTS of AMSOIL tranny fluid, and no more intermittent fault codes, slightly better gas mileage, better shifting, and lower tranny temps. Purely not saying AMSOIL is a tranny repair recommendation, but in my particular case it's all relative.

One I call the best of all oil never had problems. I have 2017 Malibu my car rans okay & rougher be for I changed oil I took my car to be tested on a dino, I think I spelled it wright if not sorry anyways found with the oil I had in the car at running at 80 MILES my RPMS WAS 3200, After changing to Amzoil at 80 MILES RPMS dropped 2700 to me that's a big difference the other oil that I can't say is one of top brands.

I drained and refilled 4 times, driving a few days in between each change. It cleared up the shuddering on my Honda that has 240k miles, giving the transmission a new lease on life.
