12 Bolt Rear End with Posi What Oil to use?

Ok just like the title says I have a 12 Bolt with Posi. What oil should I use on my rear end? Is regular oil ok or can I use Synthetic what Weight? Also Should I change it, the truck has been sitting for over a year and leaked alittle just enough to leave a small quarter size stain..How hard is this to do for someone who's never done this job before? Also since I will have the differential cover off how can I tell what gears I have?
Thanks Pablo...........
