It really does look clean as new. At first I used M1 5-30EP for a couple of changes, but then changed over to 0-20. I did notice the 0-20 does spin over a little easier in cold temps. I haven't done a UOA and see no reason, but the way the oil looks when I drain it, I'm sure I could extend the OCI several thou more. The engine sounds as quite as could be expected, and runs very well to date.
Excellent pictures! Proves once again Mobil 1's ability to keep an engine very clean.
