Default When does a new Moser 12 bolt need servicing?

I had Rapid Motorsports install a Moser 12 bolt about 1 1/2 yrs ago and 2000 miles ago. I haven't serviced the 12 bolt yet and I am wondering when it is due and what products should I use? The Moser has the following components:
Moser heavy duty posi
4.10 gears
33 spline axles
T/A cover

Change the oil. 75w-90 non-synthetic and 1 bottle of GM posi additive. It's no different than any other rear end. Not sure what else you have in mind as far as servicing????

I use 85-140 and 2 bottles of LS addative. I do this once a year as a normal maintenance item. You are due. Moser recommends changing fluid after a 500 mile breakin.
