Customer Ratings & Reviews

Great ! Truck runs really good.. Thank You !

Use this in my 4wheel Drive Truck and my Vette. Great product.

Have not broken a rear end since using this product

I use it in the rear diff on my 124 Abarth, changed about once a year given the heavier duty track use. Excellent so far!

Everything works great

Always been a fan of amsoil, this 75w/90 is now being used in my 2005 4runner with nitro gears that I commute daily with and go offroading with. Knowing my gears are properly lubed and well supported with a sever gear type for terrains and temp I can go heavy foot on the pedal without any worries.

I got better mpg's...so, less friction & less drag= more mpg's and more horse power and torque. Which are always welcome in my house!

Been using Amsoil gear oil since 1999, only one I will use. I put this 75w-140 in the 2014 Ram1500 along with their slip lock additive, great stuff.

I've been towing for years and this oil is the best stuff around. I'm switching all my vehicles to amsoil.

I use Amsoil for every application. Used their Trusted products for many years. I've never had any issues with Amsoil in any of my vehicles and equipment.

I used this product to preform regular maintenance on my Scat Pack. It quieted down the whining noise the differential was making. So far so good on this product. The easy squeeze packs made it much easier to fill the differential with fluid.

The quality is superior

Great product, ordered online, join the annual club to get the members pricing, quick order process and speedy delivery. Will order more in the future!

After I replace my differential oil .my truck running very smooth. Quality oil and I would recommend this company to all my friends

I love this stuff, I love all of the Amsoil products. I’ve been using Amsoil products for 25 years. I use this 75w90 in my Jeep Wrangler and my SRT Challenger. Can’t say anything but great about it, it does what the good people at Amsoil says this lube will do. Last longer, clean and cool better than others on the market, and priced right.

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.
