Customer Ratings & Reviews

This was the first time I had used the in-bag Easy Pack option. I had heard others say it was great but did not think much about it. My experience was really good. The bag allows full use of all the oil in the bag, and it is no mess and easier to get to awkward locations. I recommend it. I will start using it my boat sterndrive and any other application that the bag adds convenience.

This gear lube silences the dreaded 2007 HD 6-speed 5th gear noise. Make the shifts almost automatic quality!

I love the hard bottles short and do not tip over as easy as tall ones Easy to tip Knowing I have a quality product for my truck and suv rear diff is Great peace of mine

I started using Amsoil products 15 years ago in my marine 9.8 Nissan. Was so impressed cautiously started using it in my 2018 Chevy Colorado. In my new 2021 Colorado its all i use now. Everything is snoother. Cold starts, hit days , my son is a mechanic, maintenance and fluid changes will double the life of a vehicle! Amsoil seems to extend it even further!

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
