*********UPDATE + LARGE PHOTO************
2008 with 84k miles
Oil changed religiously
I'm 3rd owner bought at 60k, tracked twice ever (I have no reason to doubt)
I believe I have read before that Blackstone samples (even on an early car) can be inconclusive as they can clearly show an engine in trouble, but cannot prove one is entirely healthy. This is clearly no fault of Blackstone. I would tend to agree with this as I have clearly have worn past multiple layers on 4 of 8 cylinders.
Motivation for this procedure is that I came home and heard the slightest tapping from what seemed to be bottom end that was entirely in rhythm with RPM, and any increase in RPM (oil pressure?) would cause it go to away.
I have 2 oil samples I have not sent in, but below are three cumulative reports ending at 75k, only 9k miles ago. I feel this wear must have occured well starting before 9k miles ago.
