Smooth shifting gear oil great for the off-road on my Jeep .

The gear sounds smoother and run cooler

I really like the squeeze package makes filling your rear end easy.

Bag leaked in shipping box

Love the packaging. Easy to squeeze in there

Bought this gear oil for my Tundra Truck. Easy to use pouch allowed me to fill the diff and transfer case with ease. will use again. great product.

I've used Amsoil in every one of my rear differentials since MY 2000. I have changed each of my vehicles rear axles into limited slip axles using an Eaton Truetrac and Amsoil severe gear has performed flawlessly in each one with no excessive slippage or grabbing. This differential oil is superior to any I've used in the past. I've used it in vehicles that were driven over 3500 mikes a month tomy current vehicle that rarely gets driven 3000 miles in 6 months and it's performed flawlessly.

Awesome product

I've always used Amsoil oil , spend a little more for exceptional products. Will always use Amsoil in all my vehicles. When you go to dealer and or mechanic they use basic oils, that's why I change my own, I know what's going in the engine

Put this in my front and rear differentials. Operates as expected

Awesome, one of the best I've used

I have only been running it a few weeks, but it seems great so far.

This product is not compatible with GM limited slip rear differentials. Change the rear end fluid in my 2021 GMC 2500 HD and used Amsoils 75w-90. It ruined the limited slip clutch in my rear end. Do not risk it, you must use the limited slip additive with this gear oil. Very disappointed.

I hardly ever write reviews, but this one has been earned. I have used amsoil marine engine oil and gear lube since new in my 2011 Yamaha f40. It’s on a 20 ft work boat and if it’s not hulling materials to islands or pushing a barge with landscape materials and excavators the kids would be using it for waterskiing. It has had a tough life and still runs flawlessly after 14 years day in and day out all summer long. Engine and gear oils still come out clean after all these years I’d highly recommend amsoil marine oils.

Use it in all my rear ends,transmission and transfer cases.

Serviced the differentials on a RAM 2500 so far all good.

Sooo convenient squeezing a bag instead of pumping the oil. Easy Peazy

I have been using Amzoil gear oil in the differentials on my 3500 diesels for years and I do a lot of very heavy towing 20 plus pounds and have never had an issue! Very satisfied!

Between the drive train fluid change and the fuel additive, my truck drives like new and trust me, she's got some miles. 98 Tacoma. I get a lot of compliments. Thanks Amsoil !

I used the serve gear 75W-140 because of the extreme hot weather here in Florida. My Ford Explorer PTU is known to brake down due preventive maintenance guide line require by Ford service manual. With the high mileage this lube hopefully help and prolong the life of the PTU.
