another differential oil question

I got a 2004 Unlimited LJ with a limited slip diff. I bought 4 quarts of valvoline 8090 non synthetic limited slip gear oil. Even though the valvoline gear oil states limited slip on the bottle I have heard I need to add something else to it since mine is a limited slip diff. If so what do I need and how much for the front and rear?

Secondly my buddy has a 03 Sahara with a dana 44 rear and his has a open diff. Why does my LJ with a dana 44 have a limited slip and his does not?

You don't need to add additional additive since it's already contained in the lube. Regarding your buddy's Dana 44, the limited slip was an extra cost option for some models of TJs, and standard for others.
When you have a choice, buy American.
