Well, this is the 2nd oil change I've done, following the valve job / top-end work I had done.
Previous one was a shorter OCI, but for this one I ran the full 7,500 miles to really see what the oil stirred up.
All in all, I'm pretty happy with the results. Tells me the engine is settling in and cleaning up pretty well.
I was really hoping that Copper and Silicon levels would be back down to base levels, like they were 2 OCIs ago, but considering they have come down substantially (in ppm/mile), I'll take the trend. At least Aluminum and Iron are pretty much back to normal.
What does everyone think?
