Every product purchased has arrived quickly, and whether for my truck engine, differential or Harley wouldn't choose anything other. The proof of quality and dependability is found with little effort.

Long-time user of this product, but always bought the quart bottles. Several gadgets and transfer hoses later, I tried these flexi-cartons. Works like a charm, smaller trashcan usage afterwards, and stores in smaller space. Free shipping on a case was a bonus.

Better than ford recommended, get it.

I like the easy-pack, very useful.

After changing my differential oil on my 2006 Trailblazer with the G80 option code with GM 75W90, started making a whining noise. Purchased Amsoil Severe Gear 75W90 whine is completely gone. No mess with the Easy Pack!!!!

Brilliant! A squeeze bag. Didn't have to rig a hand pump.

Only have a couple hundred miles on truck since diffs were done. This product came highly recommended by multiple forums(Cummins, Dodge Ram, diesel, etc…).

Severe duty for my gmc 3500 Duramax pulling 17000 lb Fifth wheel- extends change intervals

Used in conjunction with Amsoil Slip Lock in a Chrysler 9.25" with 3.92 gears on a Dana Tracklock carrier. It's worked perfectly with no noise at all.

Honestly haven't changed the fluids yet to write an accurate response. But with Amsoil name on it I'm quite sure I won't be disappointed nor my Camaro.

With the price of vehicles today, I like to do all I can to protect my investment, so I try to use the best products IMO to maintain them in good working order. For me Amsoil is the way to go to accomplish this goal. Love the flex bags that make this job a breeze to do, especially in these hard to reach areas with minimal clearance.

I really the container this gear oil comes in. And fast shipping.

This is really easy to use no mess toss when done love it

I flushed the transfer case fluid for a friend, and he immediately noticed how smoothly the Amsoil gear lube flowed compared to petroleum-based gear lube. The physical properties of the signature series lubricants are far superior to petroleum based. Note: Recommend not using "Severe Service" gear lube in manual transmissions as it may interfere with proper function of the synchronizers. For manual transmission, regular Signature series gear lube should work superbly. "Severe Service" gear lubes are an excellent choice for transfer cases and rear differentials, but not manual transmissions due to synchronizers. (Fyi, I'm an experimental physicist, and have been using Amsoil products for over 40 years.)

I replaced my OEM fluid in my 2005 Ram 2500 Cummins at 43k with Amsoil Severe Gear. At 123k I replaced my diff cover and when I drained it the fluid looked and smelled like new, not like the fluid I drained at 43k miles. Of course I replaced it with Amsoil Severe Gear. I run all Amsoil.

Easy to use. Great product. My experience using Amsoil products along with other people outside, independent source test results prove they make great products.

I use nothing but the best lubricants and parts for my automobiles, there for I always look for amsoil products. This severe gear lubricant is a high quality product that I know will protect the differential gears from all the stress of everyday use. The soft package makes it easy to fill the differential without using a pump. I highly recommend this product to anyone that wants the best for their gears

What a time saver let alone the easy application no mess great idea thanks

I have a Toyota Tacoma. The front gear box oil replacement is always a little messy. In the past I had to use a pump to get the oil back into the gear housing. This bag eliminates the need for the pump. It made it so easy I was done with no oil on me and more in the truck. Great idea with the best oil on the market.

great fluid
