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.

I’ve always used Severe Gear Oil in all of my differentials and I’ve never had an issue; after 50k, it still looks clear and viscous. The squeeze bottles make the drain and fill process even easier. Spend the extra money for the piece of mind and go Amsoil.

You had your way to I haven't is gear will into the front differential on my F250 4x4 and boy did it make it feel so much better.

I use Amsoil in every engine I have including lawnmowers, farm tractors and my classic cars and have for years. Never had a problem with Amsoil products.

Trans shifts better with amsoil

I run this in everything from my bush hogs on up. Its hard to beat.

I use only amsoil oils and fluids in all my 4 wheelers and side by sides

Changed the diff fluids in my jk to this, Dana 44's

Use this on gear box on John Deere mower lower heat and great lube
