That
oil looks very discoloured from blow-by gasses. Not surprising considering the age of your engine, and the fact that it has seen no road miles yet.
Mobil 1 - is that a
synthetic?
My info is that break-in with a
synthetic is not a good idea - stops the rings from sealing. Do 5000 miles with dinosaur juice before you put
synthetic in there. Then you know the rings are fully bedded, and they won't, virtually ever, with a synthetic.
JMHO of course, and what do I know about US engines????
