Customer Ratings & Reviews

I have used this severe gear lube in my Harley ever since I installed the Baker transmission. Smooth shifts and no gear noise or transmission noise. Only transmission lube I will use in my transmission. I believe Baker makes the best Harley transmissions and they are not cheap so I will use only the best transmission lube in the industry, that is why I use Amsoil severe gear lube.

Great fluid, the container makes it easy to fill in those tight areas. This fluid is almost clear which will be great when changing so you can tell how dirty it is, unlike the competition.

Best invention ever !! The pouch style is the easiest way to refill , clean simple and fast !

I have been using the 75 / 90 full synthetic for about 70 k it was the recommended oil when I went with Banks rear diff cover. I have everything changed over to Amsoil, Confidence and delivery to my home in just 2 -3 days most of the time.

First gear oil change on my rear differential, and front transfer case on my 2021 Mini Cooper JCW Countryman and wouldn’t use anything other than this gear oil as a replacement. This car will only use the best oils!! Amosoil only…

Changed all gear oil in my 2004 Toyota 4Runner 4x4 limited. Used amsoil 75w-90 synthetic gear oil. Seems to be quieter and smoother. Id definitely recommend amsoil gear oil

Good OIL, worth the price.

If you want maximum protection here’s. Your oil Nuff said.

Rear diff runs super smooth!

Been running this in my 2021 Yamaha wolverine since new. Have had no issues with transmission or final drives.

Item is what it state it is Tested and proven quality over the years

The entire ordering process was easy and delivered to my door. I no longer have to use a pump and the mess that is created by the process of trying to get gear lube into a differential. The Easy Pack says it all "Easy".

Amsoil 75-85 Sever Gear Synthetic works great for my MY2016 Ram 2500. This is the second cycle of using the gear oil from Amsoil and I would suggest the use in your vehicles

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.
