I believe fully that Amsoil synthetics are the class of the field in all applications , I use their engine and mix oils in my quads and jet ski , so I seen their extended life gear oil I had to get it for my pickup , it might sound like an ad , but , Amsoil is all good stuff ??
Yes, I would recommend this to a friend.

I put this in the rear ends on my Kenworth, so far so good!
It's difficult to give a review of a long term oil such as differential lube. But, Amsoil in my 4.2 and my 4.0 Jeep engines was immediately noticed. Jeep in-line 6 motors tend to have valve noise on start up. Totally gone now ! Love that Amsoil ( 10w30). Now switched all 3 Jeeps to Amsoil
