You've run this oil for about 88% of this young engine's life, and that's the reason that we are still finding high
iron, copper, and silicon. We normally expect wear-in to be past by the time you get to about 10,000 miles, but when
you run long oil changes from the start, the process takes longer. You'll get there eventually, though you could speed
the process along by changing the oil at 7,500 miles next time. Note fuel at 3.0%. This is more than we like to see but
hopefully it's from rings seating. The TBN read 4.1 showing some active additive left. Check back.
