Customer Ratings & Reviews

Changing gear oil is something I dread due to the viscosity making the pumps that you install on the bottle really difficult to use, in addition to the pump not always fitting on the bottle. With a 4 or 5 inch length of tubing on the end this makes the job 100% easier. I will be using this every change, and with AMSOIL's reputation I am sure the oil will perform well in all conditions.

Squeeze bags are awesome.

I use these gear oils all the time in my vehicles, utv’s, whatever else that’s in my garage. Amsoil gear oil just flat out works and protects gears with very little wear compared to others I’ve used and drained out.

I generally run this product for 100,000 miles I'm currently at 400,000 miles and changed leaking axle seals as well the axe bearings are still in perfect condition. I have run this product and many other AMSOIL products for 200,00 miles in my 2001 Dodge Ram 3500 I'm super happy with the results.

Great product, makes 30+ year vehicles, drive like new from the factory. Nice add to my old truck.

97 dodge 12valve Dana80 and NVG4500 I run all Amsoil fluids . Truck runs smooth ,cool and quiet . I trust this stuff and run it in my all of mowers, tractor and ATV.

There is just no second-guessing when you buy Amsoil gear oils that you get the best on the market. This is something you only change every 30k miles at the most so the investment in Amsoil needs no doubt.

Great product!! Worth the money!

The plastic bag container was very convenient to fill the differential with a side fill hole. No transfer pump required.

used this before in my roadking now in my ram great oil

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

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.
