Customer Ratings & Reviews

I do alot of towing and hauling. Adding this heavy weight gear oil (AMSOIL SEVERE GEAR 75W-140) to the rear end of my '03 Dodge Dakota allows me to tow in excess of 10,000 lbs. With 81,000 miles, hardly any change in color/hue and excellent neutral roll, this gear oil might just hold up to 200,000 miles. With other gear oils, I would've already had to change it out. AMSOIL rear-end gear oil not only gives me piece of mind but also saves on unwanted frequent changes.

Container makes it easy to change on my Ram.

The container makes it very easy to change on my Ram transfer case.

I changed out the rear diff with this and it makes a big difference, even though the old oil was still an amber color.

I used to fill diffs the old way with the squeeze bottle and it was always a pain so I then graduated to using a small hand pump and tube. I then gave the easy pack a try and then r’s the only way I go now. And more sore hands, awkward bottles or pump clean up. Fits in the tightest of spots and you don’t waste a drop. The fluids performance is top quality as well but that to be expected from ams.

Great lubricant. Always the best.

The pouches make it super easy to use!

Sorry, haven't use it yet, I bought to have on hand but looking forwards to seeing it work.

I always trust Amsoil for a great product and love the packaging except for one thing. The seal must be attached with kryptonite or something because I had to use a razor knife to cut it off. No problem unless you drop debris from your cut into the product. Could you fine folks at Amsoil work on making the seal a little easier to remove?

This is my first use of Amsoil gear oil ... I expect it will perform awesomely like all the other Amsoil lubricants I use. The winner here is the convenience. I used this in the final drive for my Honda shaft driven motorcycle (NT700V) ... easiest fill ever. Just opened the container and 'squoze' in just the right amount. Quality and convenience. Super combination!

Great gear oil, I run circle track and I have not broken a rear end since Using this oil

I've been using this product for years, in multiple items. Would highly recommend.

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.
