I'm here because it is fascinating and entertaining, and I'm a curious soul.
However,there is something to be said for ignorance. I doted over the UOA's off my 06 Soltice, but with my Express, I just put either M1 or PP 5w30 in it and ran with it, changing when the olm said to change it. That van idled constantly, so I'd hate to see what the UOA would have looked like. (It spent lots of time at bank, food, and pharmacy drive-ups, and I'm sure at school idling while my wife rolled the window down and talked to friends....just idling away. We traded it with 144k miles on it, and I never saw an oil related issue with the 6.0. It was running good and strong as new when we traded Saturday. It also survived the high-iron M1, as well, as that was the oil of choice about 85% of the time.
I'd take the trip, enjoy the engine, and do one when you return, just to see what happens. The EcoBoost in our new Transit is surely going to see idle time approaching that of a police car, so maybe I'll get a couple of these done. I'll bet mine will make you feel a whole lot better about your engine, if idling is the culprit.
