After reading this thread a few weeks back, ordered Motul Xcess Gen2 for the upcoming oil change. Will be interesting to see how the UOA values trend over the next several OCIs.

Please don't forget that UOA is noted designed to tell you how the engine performs with oil, but a state of oil itself. UOA can point to an issue (rod bearings) but to get the full picture, only disassembling engine can tell you that.
