Customer Ratings & Reviews

I changed the rear differential in my 2014 GMC Sierra with AMSOIL gear lube. The process of ordering and then using the product was easy. The package makes it simple to empty all the lube into the truck without spilling a drop. I would highly recommend this product.

I use this vehicle for a combination of paved mountain driving and a very rough steep trail type road with sections of water crossing’s. I never pull a trailer except a log splitter on my property. I like that I’m able to use the 75w-110 severe gear that fits my vocation for this purpose without having to use the 140w lubricant. Next time I will use the friction modifier from the OEM dealer with this product as the slip lock modifier did very little to improve the noise when I’m on hard pavement and starting a left or right turn from stop. Very nice squeeze container also.

I wanted a synthetic gear oil to counter against the cold winter temperatures. I am trying Amsoil Gear lube. So far it seems to be performing well. The added plus for me was the ease of using the pouches. Way simpler than using a gear oil pump.

I was looking for something a little more protective/thicker for my rear differential on my 2018 Ford Expedition, as I tow a 7000 pound trailer. I was very surprised and how the drained rear differential fluid looked at 25,000 miles. It was a 75W 90 factory fill. I did not have it tested, as I’m sure it was still protecting the differential, but there were a lot of metallic particles floating around in addition to it being very dark. Made me feel good to put the Amsoil in it at 75w110. Definitely no drop in MPG.

Not sure what else to say, it's gear oil. Love the packaging and how it's so easy to pour.

I bought this to try after hearing from Amzoil Adams YouTube channel and some other channels that this quiets the clunking transmission sounds on a Harley-davidson. I haven't heard any difference, so I won't spend the money on this next time. Probably go with Redline transmission fuild next time.

I only use amsoil in all my vehicles. If amsoil sells it, I use it. Keeps your vehicle healthy and strong.

Just installed in my 2015 F-150 Lariat SuperCrew's 3:15 rear axle at 31,000 miles. Have used AMSOIL in everything I can get it in since 1983.

perfect for my tundra and 4runner at a good price to my door

This Truck has to last me so I might as well use the best

Only oil I use

I am so please with this product. First time user. I would buy more in the very near future. When ever I’m changing my vehicles and motorcycles. I’ve used royal purple but noting compare to amsoil.

Ordered oil because I needed to service my front differential on my 2014 Ram 2500, the pouch style container made it super easy to put the oil in with little to no mess. When time comes to do my rear I will purchase again

Great product and lightning fast shipping! Couldn't have asked for more.

Very good product and easy to use pouch is very nice

Good stuff

Used this gear oil on our 2017 challenger.. had to have the best for the best

I've been using this in my Harley trans for a couple years now. It works alot better than Harley Syn3 20w50 motor oil. It shifts alot easier n quiter operation.

Theses containers are great for when you don't have a pump or a siphon, def use again!

Don’t know if this was ever changed, but it’s great now very smooth
