This is the perfect gear oil for my Jeep Wrangler Rubicon with the e-locker and 4.10 gearing. I run this in the front differential for a year, then replace it. I haven’t had any problems with this routine, no rust, no nasty sludge and all original parts without any damage.

Used this with 75 w110 with slip lock additive for 01 Tahoe. Will not put anything in any of my vehicles other than Amsoil. Everything works Flawless every time

Used this with 75 W 90 and slip lock for 01 Tahoe and works great

I've used this gear oil before in my 2010 Lexus GS 350. When I purchased the 2013 GS 350 I immediately drained the gear oil out and replaced it with Amsoil. 100,000 miles later I'm changing it again. I think it offers better protection than any other product. I've never worried about protection when I use the Amazon product.

This product, as well as ALL AmsOil products I have used for last 30+ years, is excellent for Performance and Reliability

Works well so far

They really nailed the packaging on this one. It really lets you simply pour the fluid into the differential without getting pumps or scoops or any other steps in between.

This is the second time using Amsoil gear oil. I have a 2012 GMC Sierra that I had changed the front and tear diff oils at 5,000 km. The truck now had 133,000 km and I put in fresh oil. I like the new flexible container; helps make it easier to get it in. Love these oils: truck runs smoother in my opinion after installing.

Don't leave home without it

Don't leave home without it

Pretty early to tell on wear but packaging made for quick ,easy, and clean diff service.

After changing the trans oil in my 2014 Maverick 1000 xrs with this product, my trans is noticeably quieter. Also seems easier to shift the gears.

This packaging makes it so easy to install this product that I was done much quicker than anticipated! No bottles or funnels to fight with ,great job as usual AMSOIL !

First time using this product, high quality !! , very happy with the results, AMSOIL IS THE BEST !!

It’s good to know that you got a good product in your vehicle’s and your equipment And it works great

The product is great, container could use some work. The plastic cover under the cap has a thin plastic pull tap and always rips off. A while ago there was a questionnaire for how to make the products better. I still use a knife to cut open the top because of the plastic breaking. After I've opened it and after cutting the tip off the plastic don't squeeze too hard. If you do it'll drip and you'll just waste fluid. Like I said I love the product but the container could use some work. I've ran amsoil product all through my 03 duramax and now have 401,000 and counting.

Awesome stuff

👍

I will never use any other products other than amsoil on any of my vehicles.
