Oil Analysis, Iron and Lead Higher than Normal?

[GOPDiesel]

My recent Blackstone report had Iron (36) and Lead (7) higher than my normal averages of 25 and 3. Blackstone said to just keep a watch on this as I ran the oil longer with 5400 miles. This was most likely "bearing wear". Any thoughts on those numbers? One large increase they did not address was Molybdenum at 186. It had never been higher than 6 before. I trust Blackstones comments and just wanted some of your input also. No engine work was completed during this period.

Thanks, Pat

Let me guess, you are using Chevron Delo 400 engine oil? If so, the sudden High moly count is normal as Chevron now uses close to 200 ppm of moly additive in their newest formulation. They used to use pretty much none.
