My 2009 with 74k miles. Switched to M1 0w40/5w50 blend at around 40k miles and ran 4-8k OCI intervals.
Cylinder 1 starting at top of the picture, top shells are obvious as they are the more worn for each cylinder.
Here's a few closeups:
Pretty uniform wear all around with the telltale copper showing at the parting lines and along the edges
