Rear diff lube

Gonna change the rear diff lube. Does it require any additives. I have a 94 1/2 ton 4x4 with a 5.7. Thanks, Gary

Need to know if it is limited slip or not.
If it is limited slip a good synthetic 75W-90 (you should be using like AMSoil or Mobil) usually has all your addatives if you hear any poping after changing it you may need to add a bottle of limited slip addative.
If it is not limited slip then any 75W-90 synthetic or dino oil will work but if you use the dino juice then you should change it every 15,000 or so. THe synthetic is worth every penny usually good for 50,000.
