Customer Ratings & Reviews

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.

I have heard every bit of good about AMSOIL products for and finally started making the transition over

Best differential oil i have ever used!!

Use this in my Harley Trans Works Great

The only oil to use in a S2000 rear diff! Awesome stuff that holds up to track abuse.

I can tell the difference after changing to Amsoil gear lube in my 2008 FJ Cruiser smooth and quite.

love your product the only thing i use in my cars and trucks

We use it in our gear boxes for our machinery, and recreational products.
