2010 G37xS Schaeffer's 5W30 6,800 miles, 102K

Not too thrilled with the numbers, i think Mobil 1 gets better results. I'LL be running Mobil 0w-40 for the next 2 changes

While M1 0w-40 is a fine choice, I'm not sure how you're comparing the two oils to each other. All the UOAs you've done look unremarkable, with only the one at 73,000 miles looking a little sheared, perhaps due to fuel dilution, but not alarmingly so, and hey, that's part of driving.

All the drained oils appeared perfectly serviceable and within specification at the end of each interval.

I'm just hoping to see Iron a bit lower, but that may be impossible because of my heavy foot

Those iron numbers are inconsequential. Don't worry in the least. The Schaeffer's was perfectly serviceable at the end of the OCI.
