Easy to apply 10k miles later still running smooth with no noise kicks or grinding truck has 142k miles

I used this gear lube in my rear differential and it seemed to be better quality than the oem or standard oil, it flowed out a lot nicer, time will tell on the next oil change how it did

Improvement in MPG, easy to apply.

J’ai remarqué que au départ l’hiver au froid mon côté à côté est moins bruyant et avance avec plus de facilité.

Amsoil is awesome, I use it in all my vehicles

I used this product for 2000 Isuzu NQR diesel 4.8 is working good now 👍

High quality oil! And the puches were easy to use and no mess!!

Loved the packaging, easy to fill through tight fill hole location. Noticeable difference in operation of differential. Also added Slip Lock. Great products.

This oil works great for my 2008 F150 rear differential. A little pricey, but you get what you pay for. I change mine regularly at 30k because I don’t put a ton of miles on it.

Really like the squeeze bag, much easier than bottle or using a suction pump.

Easy to pour bags, would definitely recommend to anyone.

Best oil I have bought and will not buy anything else.

Purchased to change the lube, in our ‘22 Durango AWD. Gear lube works as described. Vehicle feels smoother. Enough so, even my wife who knows nothing about automobiles said she can feel a difference. Highly recommend.

The product itself is as good as it gets. Have never had a problem while using it and I'd highly recommend. Service was as good as at can get. Product arrived packaged well and a day earlier than expected.

Put in a Lotus Europa transaxle. Shifts better ,replaced shifter bushings but I think this helped about the same. Leaks a little more though…bummer..

Great price and Amsoil I beleave has great products

I had one of the pouches show up open. Amsoil's great customer service replaced it no issues. Excellent product, I will buy again. Because of my positive experience I will try out the oil for my next oil change.

Just what I needed. Thanks AMSOIL for another product I enjoy using! Highly recommend this product! Really like the packaging easy to use!
