I'm familiar with the effects of gasoline and oil additives on UOAs. It's normally easy enough to spot such anomalies on one's own, as I did here:

Hmmmm, then why have you been silent on this issue so far? And why do you continue to lump together the total metal readouts in the UOA as if they are completely a result of wear? I completely reject your single-minded focus on UOA metals as an oil quality indicator. There's so much more involved that you're failing to account for.
In the thread you linked to, above, you also made the blanket, unqualified claim that Mobil-1 causes high iron levels. Really now?
This is a UOA of our Sequoia, Mobil-1 and very low iron.
No iron problems in this M1 fed G35.
And here's an LS1 on M1 with low iron.
Same story for this V-6 Accord.
And here's a bunch of low-iron M1 UOAs done on a Civic.
But I digress. As Pablo so clearly pointed out, this is your thread, your assertions, your responsibility to prove them. You seem to think that all you have to do is toss out a claim or two, and then its someone else's responsibility to step forward and disprove your conclusory claims.
You claim that there's no evidence at all here about syn's superior performance??? Oh, how about this one:
The 1999 Porche that still had its factory fill M1 in 2004 -- TBN still 5.9 and wear, incl break-in, fine! OK, smartypants, find me a dino UOA like that one -- I won't be holding my breath. You won't find one, because the dino would be goop at this point.
You also make much of what is or is not to be found in our motley collection of entertaining, but hopelessly non-standardized, uncontrolled UOAs, as if that's the only source we may look to regarding the comparative quality of dinos and syns. Wrong again! I suppose that those Corvette engineers at Chevrolet, and all those at Mercedes-Benz, and VW-Audi, and Porsche, etc. who
require the use of synthetics in their engines were all just smoking crack when they decided to require synthetic oils. But I'm sure you'll come up with a sporting attempt to explain that away.
Look, dinos and syns are different answers to different problems. As I've clearly said before, if you're a 3/3 guy, current dinos are fine. If you want to go into the longer-range OCIs, the deeper you go, the better an option the syns become.
But again, your thread, still waiting for you to prove your claims.
