Yep, it was a pretty good UOA, although very short interval. As for the fuel dilution, at next OC I’ll replace the first oxygen sensor, plugs (NGK iridium), and if I manage to find them, coils (if you have an idea of the ref number.tell me, for now I’m at loss). I don’t have a code yet but I think the heating part of the oxygen sensor is shot, as it is on my yellow Barchetta...
Since this UOA I’ve been going back and forth between SHU 0W40 (Pennzoil platinum in the US ?) and the Cooltech Petronas, and definitely prefer the Petronas, noise and smoothness wise. This engine also likes thin oil, with my grandpa style driving, and the Petronas is on the thin side of a 40.
