Customer Ratings & Reviews

This went in my 2005 tundra I use for mowing service. Works great. Has a limited slip differential. Thank you for producing premium products for peace of mind.

I used this on the front axel of a Kioti CK 2620hst compact tractor for the 50 hour service. I’m not sure what the Kioti factory uses for the front axel but I’ve read several forums that claim they use hydrolic oil instead of gear oil. This gear oil along with 15w40 synthetic motor oil has my tractor running much quieter than it ran with factory provided products.

I change all my fluids every 75k miles on my 1500 silverado and every 50k on my ram 2500. Neither has givin me any issue since I made the switch to amsoil. My silverado would lock and unlock the rear dif going down the road and almost ass soon as I switched to amsoil it stopped locking unnecessarily. It has been quiet leak free and we'll protected with Amsoil

The easy pack allows for hard to reach areas, which unfortunately is very common.

Best synthetic 80w90 oil

Saw plenty of reviews and decided to go with this for my gear oil. So far so good!

Awesome product

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

Working great easy to install

Been running this oil for a while with great results.

Being in the bag makes filling easy! This product also is better than any other product out there!

Use it in almost all of our vehicles, can't go wrong. It gets pricy when racing, no failures from oil yet, and don't expect any using this product.

Change it once and forget it. Never an issue with the limited slip differential. Towing a 6,000 trailer and never an issue. Just the fact this is synthetic, it will out last anything else you would use and protects for thousands of miles. Less worry and more driving make this a worth while investment

I did my transfercase and diff fulid, running alot smoother and fuel economy has improved!

This oil is the best to work with. I use this oil on all my 2-stroke machines for maximum performance! Highly recommend this gear oil!

Best gear oil you can buy.

Products are good, and love that they test there products against other oils.

I don’t know if it’s just a sense of security because I swapped out the unknown fluid in the rear end of my RX7 with Amsoil. But I feel like this fluid really helped smooth things out in the rear end.

I recently used AMSOIL Severe Gear 80w-90 to replace the rear end oil in my electric golf cart. While the manufacturer recommends SAE30 for this application, I just couldn’t bring myself to use MOTOR oil for GEARS. The Easy Pack packaging is incredible and very easy to use. Despite not putting it to the maximum test, it’s been working perfectly so far. I referred to viscosity charts and chose the closest option I could weight-wise to the recommended SAE30. Overall, it’s been a great choice for my needs.

my kaiser M715 shifts better now that it ever has especially in cold weather, 11k miles on it. I also run amsoil in my 2014 ram 2500 4x4 automatic diesel,125,000 miles on it
