Looks like my numbers are somewhat trending towards the current formula now. I was unaware the formula had changed so i was mixing bottles before causing a lot of confusion.
My reason for changing at low miles was due to MIL and I was going on a trip towing my camper.

COMMENT: There are no complaints to file regarding your the EcoBoost in your Expedition. Wear metals are lower this time after the shorter run and there's nothing wrong with that. Iron was a bit high in June of last year, but in both samples since then, iron's wear rate (ppm/mile) has improved. We don't see any reason why you couldn't try 6,000 miles on the oil again. The TBN of 4.2 shows active additive left for a longer run and fuel dilution dropped to 1.3%. That's just from normal use rather than a fuel system problem. Looking good from here at 21,030 miles.
