I have a G80 Eaton Locker and this is exactly what I needed for it.

Good diff gear oil!

Simply the best. Exactly what my car needed. Running smooth and quietly

I’ve recently made the switch to ams oil in my 2015 Silverado after conducting several stress and wear test of my own in our shop I was so impressed with the wear properties of ams oil that I’m going to use it in all our equipment around the farm as well as our personal vehicles

I am using Amsoil in this truck since recently purchasing it. Once I change the fluid again and have it analyzed I will know for sure if it was worth the money. 4 stars because of this. I do think from what I have read that Amsoil is a superior product, but I will not know until I use it for a few years.

Awesome product ., use it on my gear box of my Aeromomemtum Engine

This product does what I need and appears to be exceptional.

This is the 2nd rear axle fluid change I have done. 50k of towing and daily driving did not seem to phase this lube. No cooked smell, no sludge. Works well without the additional friction modifier.

This product keeps the differential cool!

Fresh axle build for a bronco project. The 9” and D44 both got the good stuff. I’ll see how they look in 500 miles.

Used the 75W-140 in the rear of my F-250 SD (came with a New Banks diff cover as a package deal). I loved the ease and convenience of not having to hand-pump the fluid into the diff. The Easy pack was GREAT and no spills, no mess! So, when it came time to do the front diff, you bet I found the 80W-90 easy pack for the front also. Highly recommend the AMS oil for the packaging and of course, the reputation for lubrication products.

So far so good. The flexible bag was easy to handle and the Ams Oil videos were helpful.

Good product..highly recommend

This bag makes filling a diff much easier And with no mess...

Meet the OEM Specs. I'm happy of the quality and product longitivity

All lubed up and ready to go.

I use Severe Gear synthetic lube in every differential, transfer case, and manual transmission that I own. Superior performance and quiet operation in any temperature and in very hard use in my 4WD trucks and tractor. Extended drain intervals. A great product; worth the extra cost for me.

Had to do a oil change on my F550 front diff. Ordered the SEVERE GEAR 80W-90 in the Easy pack.. The Easy pack made filling the diff back with fluid 100% easer and less mess/ waist. Highly recommend
