Rear differential oil change.

(2002 Chevrolet Silverado 1500)
in Burton, MI on March 22, 2011
I want to change the rear end fluid in my 2002 2wd long bed 1500 Silverado. Does anyone know if there is a special additive or friction modifier that GM requires when changing the fluid? Can I just refill it standard, stand alone 80w90?

as long as it is not a limited slip or posi rear.
