Here's another UOA for people who enjoy this stuff. It looks like 22ppm for Iron is a fact of life with this car. The last analysis was done by a local lab (at 16967 miles with same level of Fe) so that's why it's not on Blackstone's history. BTW, the Cu levels have been dropping down which is to be expected. All comments are appreciated.

Regards,

I enjoy these... I just have no idea what they mean :)

Does high Fe mean excessive wear on the engine?

"High" is a relative term, so the idea is to keep doing the analyses and trend the data so problems can be anticipated before a component fails. properties of the oil is nice to have as we can see how the oil stays within grade (viscosity). Here's some info of where the wear elements can come from and how to read a report.
