hmmm, well, I don't think nissan has changed out the specs for the diff fluid recently, so I'd lean towards the service tech putting in the wrong oil.
That said, I wouldn't worry too much about it. I'm actually going to be swapping rear diff fluid very shortly and will be running motul 75w 140 myself as per forged performance's recommendation since our rear diffs run so damn hot, esp under track conditons.
