I'd try a 0W-40, or 5W-40 to see if numbers go down. I think a 40-weight is allowed, no?
No sir, just 0w-30. You may be thinking of the 2.9L in the Quadrifoglio which specs a 5w-40.
This is ACEA C2, C3 . 40 grade would likely do nothing here where it counts.
I'd just wait till next UOA and go from there.
