I'll say exactly what I said in the other thread where this was posted:
It says that their "analysis" (AKA document research, phone calls) indicates that it is full or partial synthetic. While this is probably true, the statement from Mobil 1 is too wishy-washy to mean anything.
And besides, this comment is coming from a company that markets partially synthetic Group III-based oil as "Fully Synthetic." We can thank the US Government and their infinite wisdom for allowing that nonsense... ugh.
BTW, this is old info, and was long since disregarded as conjecture on Mobil's behalf on BITOG.

You'll usually see elevated iron wear for several thousand miles on a new engine. Eventually (think 10k+ miles) it stabilizes. This doesn't mean the engine is not effectively broken in, of course.
