Iron is definitely high. The highest I've ever registered was 7ppm on 7,000 miles of Castrol Edge 10w-60.
The bigger surprise to me is the 0 for lead (rod bearings). That's pretty much unheard-of, and spectacular news.
For reference, my most recent report, which just happens to be my best to date:
My Molybdenum is super high as a result of running Cera Tec, which I started using ~25,000 miles ago.
