Customer Ratings & Reviews

Honestly, never knew something could take such a beating. Between towing, and off roading, has never left me wondering.

It is a great product. And the easy squeeze packet is fantastic to use

It's always a great feeling knowing I have Amsoil in my differentials. Whether I'm towing my 40ft fifth wheel or 6 wheeling my F-350 Dually 4x4. Amsoil has got my back!

Bought enough to do both front and rear diffs in my Ram 2500 4wd. Squeeze packaging made it easy to fill.

Amsoil is the best straight out

makes shifting much better

I bought this to do my rear diff and also for my extra front diff that I am rebuilding. Then I decided to put it in my existing front diff even though I know it leaks on both axle seals. To my surprise today, while I was doing a oil change on my 2013 gmc sierra 6.2, ( amsoil 5w-30) I noticed that my front diff has stopped leaking. So at this point I am totally impressed. Next month I will be doing my tranny and transfer case with Amsoil signature series fuel effecient 100% synthetic tranny fluid. I am quickly becoming a fan boy of amsoil products. I can't afford a new truck so I have to give my current truck the best treatments I can. Thx Amsoil

It only makes sense and just a few dollars more to get the best performance and protection for your vehicle.

Put this in my 2015 camaro ss dif. It seems to work so far

I had some significant noise coming from my driveline, I have a 2016 Ram 1500 4x4 and figured it had to be the differentials, it was, used the severe gear and noise gone. Very quite ride now. I pull a compact tractor frequently to severe gear was the way to go.

Quality product, stellar reputation, easy to use!

Love the squeeze containers, convenient, fast, and clean fluid change. Peace of mind knowing I won’t have to do it again for a while with the Amsoil fluid.

Running this on all my trucks for over 200000 miles on heavy duty towing,, very minimal wear on my differentials. Extremely recommended!!

Great product easy to use.

Used for Transfer case and Rear Differential on a 2019 Rav4 adventure model. It's been installed 2 weeks now and driven 1,000 miles. There is no loud noises and it's still running, so that's a good thing. Any difference?, none I can see. It will be when I change it out again to see if any changes in the color or smell. As for the soft packs, I should have got the quart bottle. I use a pump to fill the cases back up and this was not working, guess it could be my pump, but I filled a container and was able to pump out of that. Anyways, this is supposed to be great stuff, we will see.

The bags made the job super easy!

Severe gear in diff on Challenger R/T, definitely smoother and quieter. OE gear oil looked like metallic paint at only 4,000 miles

I like the review on the oil

Great product and functions excellent in my Ram 1500

packaging is perfect to use when filling the diff on my truck
