Ruh roh! I just got the analysis results back from my last oil change and the printout shows a couple of abnormal numbers, specifically, slightly high Aluminum (7 ppm) and Nickel (11 ppm). The comments section says "WEAR METALS APPEAR SLIGHTLY HIGH FOR OIL TIME, RESAMPLE NEXT OIL CHANGE TO CHECK WEAR TREND"
I figure that I'll fly it to another oil change and get another analysis done (obviously) to check the trends, but what components wearing will show high aluminum and nickel? The oil filter and sump screen were clean with no metal that I could see, engine has 685 hrs SMOH, cylinders are ECI Cerminil. Compressions are good and oil consumption is around 8-10 hrs/qt. I've had 7 previous reports with no problems, all done by AOA in Phoenix.
Should I be freaked out by this or just wait for the next oil change report?
