Customer Ratings & Reviews

Using this in the rear diff of my Polaris Ranger 500 efi. Works great, easy to use. Will keep using it.

Keeps my #5 drives happy, so far nothing but on the magnets .Trump 2020

Like the packaging,easy to use in tight places

Great gear oil, hear less noise, can feel smoother operation, highly recommend.

Amsoil always has great reviews and I get great results from their products. I take maintenance very serious with my 2015 Tundra. Sometimes you have to drive hard.

really easy to use, and works great

Like the other Amsoil products I've been using for many years, I've yet to have a failure with anything mechanical on any of my vehicles or motorcycles. I can only say that when a product works, keep using it. I tell people that I change oils and lubes religiously once a year. Of course, gear oil is done every 40K miles.

Awesome product

Stuff works awesome.

I run Severe Gear 75W110 in the drive on my boat. I have a fairly lively 383 in front of a drive that's not designed for more than the torque of a stock Chevy 350. I have added the Amsoil lube and an external cooling shower to the drive. It is on it's 4th summer and showing no signs of trouble. I also have Severe Gear in the 6 speed standard transmission that's in my Turbo Regal. When the axle carrier bearing failed my trans spilled it's factory pour. I didn't even think twice about what gear oil to use after the results I am getting in my boat.

I wanted to be assured that I was doung my part protecting my truck so Amsoil it is.

This product was part of 45,000 mile rear diff oil change. The biggest change I noticed was that when I put the truck into reverse after sitting over night I no longer get a metallic thud when backing out of the garage. It seems as though the oil provides a cushion layer between the gears. I do not track gas mileage or tow a trailer so I can not attest to those issues but I am sure this product would help

Replaced RCF TVD rear diff fluid with severe gear 75w-90 and I felt an instant smoothness when I reversed. It didn't feel stiff or feel as if there was any resistance. Gone 1000 miles so far and it still feels lubricated.

Another great Amsoil product. I used it in my BMW K1600 GTL drive shaft. These drives can be a bit sloppy but it seems quieter and more precise since I put in the Amsoil.
