Customer Ratings & Reviews

Great product, arrived quick and the packaged is very convenient.

Have not had a chance to use it yet, I will on my 2001 F350 diesel as soon as I can it on a lift

Best lubricate available! My son put me onto AMSOIL over 25 years ago. I use it on all my equipment on the ranch. Trucks, tractors, feed wagons, 4 wheelers and gear boxes. I've had two run around little pickups that I put over 400,000 miles on running on all kinds of roads dirt, gravel and paved. And only changed the oil every 25k miles. Even on my tractors I have been able to double the hours before changes. Yes American runs on Freedom and that's not Maga it's real AMERICANS that run on AMSOIL !

Cut the whining noise down by 50%. Love it! The bag is a great design too.

Honestly, I could not tell you if this is better than other products. Have used Amzoil gear oils for many years with no problems but I’m pretty easy on my vehicles.

I put amsoil 80w90 in my 2020 ford Ranger's front differential, as well as the rear differential. I know this stuff is better than oem stuff. I feel a lot better knowing the gears will be in good health. It was super easy changing the fluid. Just fill up fill it runs out and boom , your trucks safe. Thanks amsoil

If i could..I wouldn't use anything but AMSOIL. Thankful.....Greatful.. Truck runs really good !

Always been a fan of amsoil, this 80w/90 is now being used in my 2018 tundra 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.

Good stuff

The product was installed. So far so good.

very good ,,excellent product

Perfect rear diff fluid for my 2wd '03 Tundra, with the limited-slip diff. Already has the friction modifiers it needs. And the pouch made it super easy to get the fluid in the diff

I decided to change my Differential Fluid along with my transmission Fluid since they work together and even though my Old Fluid was clean I just felt better knowing it’s been changed since I didn’t know the history of my Lexus but I’m highly satisfied

No mess. Pouches made it easy

I run this in my truck and in my jeep and both are driven very hard and often overworked and abused and have never had a rear end failure while using this fluid. I have had issues in the past with other brands of fluid while towing or off Roading, but never with this fluid.

I recommend this product

Great product , the easy squeeze container is genius. Well designed, well made and most of all easy to use . Cut my labor costs down and time saved.

Superior lubrication quieted the noisy straight cut gears in the front differential of my Honda Talon. Worth every penny.

Very high quality gear . the only gear lube that i would used

I run amsoil fluids in all my rigs, but recently swapped out the old trans fluid in my 89 Suburban. The shifter feel is noticeably less knotchy and much smoother.
