Seems like good oil that could go to the OEM spec 7.5k mi OCI, but low moly and high iron indicate wear on the higher than average side to me. High aluminum and iron could be anomaly or characteristic of not quite enough protection with the oil you used, as viscosity is on the low end of the range for that weight. You'll need to get additional UOAs and build trend data and keep track of what brands of oils you're using.

Mobil 1 since the day I bought it...but this is only the 3rd oil change since purchase.

Not a bad report, nothing spectacular but nothing bad either. Copper and lead are decent, so bearings are wearing normal. Iron (cylinders, rings, and cams) and aluminum(pistons) wear numbers aren't too bad, still decent. The viscosity of the oil is heading towards a 20 weight, but still in the low 30 weight area, so it sheared down a bit. The oil has a pretty good additive package in moly, boron, zinc, phosphorous. Like mentioned above it is good ot test the oil over time and track any trends that may be occuring as the engine ages and is driven in different circumstances. I'd probably go with an oil that holds it's viscosity a bit better and doesn't shear down as much as that oil did, but it isn't a big deal overall.

As far as the actual numbers go, these don't mean much for the typical car owner. I can't really read much of those printouts due to the resolution, but all you need to know is what the lab's comments are and how the numbers compare to the stated "average" or "normal" numbers. If there was anything alarming, the comments would indicate that.

This looks like a pretty typical engine wear pattern for the F22C1 after 5K miles of service. Follow on UOA's will allow you to spot any unusual increase in wear metals. If you plan to continue using this oil formula, it would be helpful to get a clean sample tested to see if they are using additives that might contribute to wear metal readings. Also, it will show what metallic additves are organic to the formula, especially Na and K. ICP readings of these elements is how Blackstone determines coolant ingress. Coolant detroys the engine oil, which in turn detroys your engine. Based on the flashpoint reading, I'd say that fuel dilution is not an issue. If this was a 30wt engine oil, then it sheared out of grade and needed changed.
Thanks for posting this UOA (even though it's hard to read!).

OP should check out BITOG and see if he can find a VOA for the same oil (this is adequate to sending in your own VOA isnt it?) and other UOAs to compare against just to get an idea.
Edit: It would be great to have a gallery or pinned thread to catalog all the UOAs from this site.
