Customer Ratings & Reviews

The difference is night and day regardless if it is well overdue or just a routine flush. With harsh New England winters that brings -0° temps and 3 ft. snow drifts, this is the only lube I trust to keep things running smooth through the unexpected. I recommend anyone who has a 4WD or AWD vehicle to buy this now and save yourself from any future gear troubles down the road.

I love the gear oil; however, would order the easy-pack next time. The squeeze bag would save a lot of time and effort versus pumping from the traditional quart bottle. Excellent product, though.

Rear hubs on our Trek motorhome got so warm you couldn’t hold your hand on it. Sid some research and Amsoil seemed to come out on top every time. It was hard to find a dealer so I ordered online. The rear hubs run considerably cooler now.

Use it in the quad, and the truck, works great. Especially like the ease of the Easy-pack for getting into impossibly tight spots.

If you ride in the southeast you know how hot it gets and if you ride a bike with an M8 motor you know how hot they get. This gear lube is essential to me in the transmission in my 23 Road Glide. We had weeks where the heat index was 110 and over and this product has the viscosity to handle the heat. Amsoil has always been my go to product for lubrication.

Much better gear oil than OEM. If you tow a lot you need this gear oil....or if you don't tow a lot but occasionally

Worked great but they need to add one more to their kit

Great product and even better customer service.

Great product and even better customer service.

We've been using Amsoil products since 2012, and have never been happier. When it was time to change the differential oil, I used the 75-110 weight gear oil for a change as we tow heavy on long grades in 100 degree temps. The oil never quits protecting fully. With the addition of the Banks diff cover, it also runs considerably cooler, so a win, win.

Absolutely love my seller and will always buy his product, i Absolutely love amsoil!!

I have it in all my cars differential on all my Subarus works great .

Another great product by AMSOIL

Phenomenal stuff, can't recommend enough.

Can't go wrong with any amsoil product.

Awesome product, I’ve been using it for years….. Highly recommend!

Great gear oil for the price

This is the only gear oil I’ll use on any of my cars

Used when doing a drain and fill on my 17 f150 5.0. It’s not the manufacturer recommended weight but I’d rather have a little thicker oil in the diff since it’s such a hard working part of a vehicle.

After driving free miles noticed my shifts of my Jeep was quick and smooth!!! 👍👍👍👍👍👍
