Default differential lube

So I was in the parts store picking up some royal purple 75W-90 and asked the clerk to look up for sure how much each differential took. He said that the back took 2 and front took 1.5 but that I was using the wrong lube. He said I should be using straight 90 weight.

I have used 75w-90 in the rear and 80w-90 in the front. What does everyone else use?
