hope that wasn't too confusing.
Stage 2 cobb tune 93
Thoughts? I am now running rotella t6 5w-40.
A little too much break-in noise to say much about the UOA IMO. I don't know why this oil doesn't get much respect. Decent moly, calcium, boron, and ZDDP. A little bit of shearing to a 30 weight but that's not unusual.
