The weight of the diff fluid is in the owners manual 75w90 I believe. Buy a good synthetic that says it has limited slip additive so you don't need to worry about that.
I use RP. Some sources say it doesn't last as long as others. Mine gets changed once a year which is about every 1,000 to 1,500 miles. I do get better MPG with RP over Valvoline or Castrol.
I buy a dif gasket and coat it on both sides with grease. This goes on easier and cleans up better than using RTV.
