Blackstone comments:
Universal averages show typical wear for this type of engine after ~5,300 miles on the oil. You went over 2,000 miles longer, yet wear metals compare pretty well. Iron read a little bit above average here simply because of the longer run. We did find silicon, which could be from harmless sealers or it could show dirt getting into the oil. It wouldn't hurt to check the air intake for any leaks just to be be safe. The fuel is fine since this amount can come from normal operation. The TBN is good, try 9,500 miles next?
I had the infamous intake manifold leak. It was replaced, the oil change before this one. So I'm hoping the silicon will go down next oil change.
