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

New package makes installation a breeze!!!

I think that the AMSOIL flexible container is literally the best thing ever. For those hard to reach applications where a normal 946ml rigid bottle can't get to without using pump. Just squeeze the oil in and done, no mess and no pump!. Another plus is the the overall plastic waste footprint is much less than a rigid bottle. Less waste in the application and less waste for disposal!. I can't say enough about the quality of the oil and how far superior the packaging application is.

Replaced the differential gear oil in my truck after the 500 mile break in period. Still in the process of installing power disc brakes and unable to comment on the product. But the Squeezable oil bottle is the way to go. Had an original 1 gal. pump bottle and that was a pain. Let it sit in the AZ sun for a while and it was so easy to put through the fill hole without any mess. Ordered more for my tother truck and motorhome.

This stuff is way better than the Lucas I was using in my oil bath axle trailers. Time will tell if it really is better.

Great gear oil have noticed a 3 mpg increase in my wife’s Jeep Wrangler with nothing else being changed. I did both front and rear differentials. Also it doesn’t smell awful like most gear oil which is nice.
