Customer Ratings & Reviews

I liked the fluid and packaging so far. However my reasons for 4 stars was the cataloging was wrong for the specific capacity of my vehicle and what I initially ordered was not enough.

This fluid is without a doubt better than Polaris fluid!! This is all I run in everything all terrain I have!! Amsoil knows what they are doing and they produce some fluids second to none!! This is why amsoil is all I will ever use!

I use this in my Can Am 650. Although I’m no scientific specialist, I trust Amsoil to get it right.

Severe Gear oil has really smoothed out my bike’s shifting , that loud clunk while going from neutral to first gear is almost gone. This product is another winner from Amsoil!!

This is the first time I'm running this gear oil. Replaced the rear diff in my truck and decided to start with this oil. If it performs as well as thier engine oils I'm happy

The gear oil is excellent. 👍

After having my oil changed in both the rear end and front differential my truck feels like it is running more free.

Hey its gear oil but it's great gear oil.

My one ton RAM is used almost exclusively for towing our 34 foot fifth wheel RV. It has 52K miles of which 41K is for towing. Differentials have had their second oil change and still no whines, clunks, leaks etc. When it works I keep doing the same thing.

Great product easy to pour

I purchased my 2008 mustang bullet about a year ago and I felt I should change all the oils so I know where I'm starting at. My vehicle has 96,000 mi and I feel that this is going to be the last time I changed the rear differential lubricant. Why not use the best, amsoil

Ever since I purchased my 2016 Ram Power Wagon, I've always known that if I do not take care of her, she will not take care of me. And that starts with quality fluids and lubricants. I was initially skeptical because of the price of the fluids I would be using in my beloved truck. However, after using the Severe Gear Synthetic Gear Lube and seeing the lubricant after use... I am confident that Amsoil is looking out for my truck and provides me with good protection.

Great product definitely feel a difference.

This is an excellent product worked very well in changing the fluids in both the front and rear differential in my 2005 Dodge Ram 3500 4WD. Very easy to use without any pumps> I would give this 5 stars any day of the week

replaced old gear oil, with Amsoil, truck runs great

Excellent stuff never wasted a drop with the easy squeeze pack

Severe Gear synthetic keeps my trans and diffs happy in all temps and rev ranges, and has quieted down some slight synchro noise I was developing with factory grade synthetic. If this can keep up with the way I like to drive, it can keep your car happy too. Now if AMSOIL could help me get more slick about getting out of tickets…

Awesome gear oil...top quality at a great price!

The gear oil arrived super-fast and in excellent condition. I put Severe Gear in my 2013 Equinox, and it runs just like new.

This gear oil covers a huge range (75/140). The result is a better protection and it shows during oil changes . The oil is not discoloured , tinted or full of contaminant . Best gear oil !
