Regarding units: mg/Kg is the same as ppm which is what Blackstone and all the other North American labs I have seen reports from use.
Iron is an important measurement, you do want this measurement. The Al and Cu are both kind of high in the report.

997.2 c2s 110,000kms (68k miles)
Iron value is 18 mg/kg

seems high, am i screwed?

Presto, start running an aluminum billet magnet drain plug from L&N Engineering, and see what you collect. FYI- torque spec is a low-low 19 ft.lbs.

Yep, that's high for 5k miles. Here's a whole series of oil changes from my wife's 997 3.8L. Even when I missed an oil change and went almost 8k miles, none of the metals saw double digit ppm levels. You'll also notice the Driven oil, even at higher mileage intervals, does a better job of eliminating iron wear than the Motul xcess did. Only the first analysis after the change saw iron levels close to what they were with the Motul, and each one after that with Driven DT40 has been lower. It's also a good example to show how going beyond the 5,000 mile change interval negatively effects wear metals (highest aluminum ppm), viscosity, and flashpoint. It also shows how the oil becomes quite acidic going that many miles, which is bad for internal engine metals. When the TAN number exceeds the TBN number, the oil is more acidic than basic, which is not what you want.

2009 C2S 170K miles......
OK all, have at it!!! Tell my my car is about to explode!!! I definitely am using more oil... I don't know why. Liqui Moly Leichtlauf 5W-40 with one bottle of Ceratec. Why this oil combo? I dunno. Oh, and I do cold oil changes!! Ha!
