Customer Ratings & Reviews

First off, the easy fill packaging is the GOAT! Super easy for fill those hard to reach fill plug holes. I decided to try AMSOIL gear lube while installing a new pumpkin cover. I also swapped out their ATF and engine oils. I can say I do get better MPG, as I saw my MOG climb using the same tank of gas around town. I’ve got a 60 gal. For the first half of the tank, was at 12.1, for the second half, 13.6. I can’t wait to test on a long trip. My truck is quieter overall and feels smoother, and wants to go more so than it did before. I’m a believer and will us all AMSOIL lubricants going forward.

Good squeeze bottle and a free sticker

Been running this in all my vehicles.

Great product haven't had any problems with any gear boxes. Or bearing since I started using amsoil.

AMS Oil has kept my 2002 Indian PP 100 motorcycle running smooth for all those years. I only use AMS oil on all 4 of my motorcycles.

After switching from Mobil one, I have noticed better fuel economy and less noise from the front and rear.

If you are on the fence about buying these fluids for your vehicle, go get them. They are worth every penny, my diesel runs much quieter, smoother & the oil is cleaner when I check it during normal intervals.

Best lubrication for any rearend when maching the product to your application

The purchase process was easy, and the shipment was fast. The oil is of great quality, and the easy pack makes it easier to use. After my first experience, Amsoil has me as a customer for life. I recommend it.

product is great, dispensing is great. Delivery on time and packaged well.

Awesome product it was very easy to use just open it up take off the seal snip the tube and squeeze

Needs to come with a short hose to make even easier in tight space

Used Ford's 75w-85 at my previous drain and fill of the diff. I used Amsoil for this drain and fill and noticed the diff runs smoother.

Outstanding, love the brand so my truck is fully synthetic now! Trust Amzoil!

Works so good I put it in every location on my truck. Front diff

Having a truck, towing a travel trailer or boat, or going fishing or hunting with your atv, you do want à reliable and safe products to use in your limited slip axle! There you go, I tried other brands and no other oil is performing smooth as Amsoil, even in cornering with a good load! Thanks to Amsoil again.

I use this in both my trucks. Factory fill for my old square body is 80w-90 conventional. Amsoil gear lube is far superior! Factory fill for my centennial edition is 75w-90 and 75w-85. This Amsoil gear lube is also far superior! Buy it, use it, run it!

This is the second time I am using this oil on my truck and so far it is still performing very well.

Great products can't say enough about it . This is all I use.

This stuff is the best long lasting gear oil I have ever used and the only one I will put in my Tacoma. My magnetic plug picks up less metal with this in my differential than any oil I have used to date. Nuff said!
