I have a 23 Armada with the same engine of course. Original owner. At 8,800 miles currently, I've done 3 oil changes and 4 oil analysis. The factory fill was dumped at 1,785. I have not cut open any of the filters to check for debris and will do it at the next oil change. I suspect that the two 10k drains with 0W-20 didn't help matters. User 'JTK' in this forum commented about the Nissan GDI and drain intervals. I hope the best for your situation.
