Customer Ratings & Reviews

Runs smoothly. Slightly better fuel economy. Not sure if rear diff fluid would actually affect MPG.

Purchased this for my Ural motorcycle, which is very hard to shift due to the old-style transmission. Noticed a huge difference in the ease of shifting after switching oils.

We all know the quality already, I spent $130 on 4 L of 75w-140 but it didn’t even come with a sticker?!?

I take a lot of family road trips and after switching to the AMSOIL you feel the difference in the quality of the oil.

Transmission shifts perfect

Outstanding product as always

I use this gear lube in the front differential of my Jeep Rubicon and it has held up extremely well. Last time I drained it to do the axle seals it still looked like new after 25k miles and the inside of my differential was spotless with no signs of wear.

Better quality and price than the BMW brand.

Used different name brands of gear lube in the past, but decided to try this one this time around. Right after I took it for a drive, you can feel the difference on how it drives. The drive in this 19 year old truck is so smooth that it feels like it is brand new.

I have used this product for many years now after experimenting with HD Screaming Eagle, Lucas, Mobile 1, the purple stuff and red stuff. None compare to Amsoil. Much smoother shifting and prolonged protection for hard shifts and hot days.

Not a review of the product, as much as the container- I changed the old in both diffs and the fluid in my transfer case, and these collapsible bottles were invaluable and let me add fluids without using a transfer pump. So cool, I hadn’t seen these before.

Would recommend to ever

I recently changed the differential fluid in my 2018 Chevy Silverado 1500. 75W90 in the front and 75W85 in the rear. The Easy Pack made the job much easier and infinitely cleaner. I would highly recommend it to anyone even amateurs like myself.

Just completed the 100k mile service on my Ram and of course I went with Amsoil for the differential lubes. I use Amsoil lubes in my ATV drive train and the performance is great. The ATV gets punished severely so I know with Amsoil in my truck I will have no worries. Getting ready to change all the drive train fluids in my Jeep and will surely go to Amsoil for that as well. It's protection that goes above and beyond.

I used this to replace the front and rear difs on my Ranger Raptor. The best gear oil for my application

I had a skip in the transmission in my 2022 Explorer King Ranch with 60k miles. I changed trans, both differentials, and transfer case fluids with amsoil products and it runs better than when I bought it and the trans issues are completely gone!

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!
