Oil Lab Results - what's " Normal... "

[Archer123]

Received lab results from my latest oil sample. Iron - Chromium - Aluminum all elevated from a year ago. Have owned the plane since day 1. This is the original engine... has less than 700 hours...leak down test all good... oil consumption normal. Oil temp / pressure all good.... she runs great !

YOY increase in the numbers below...but I can't find any reference as to what is considered " Ok" for these elements. Just looking for any input / experience. This is new ground for me...

2019 Iron 40.6 ..... Chromium 6.8..... Aluminum 13.1
2020 ...... 58.8 ...................... 12.2 ......................16.2
