oem filter doing it's job. I'd cut it open and inspect for gunk. No TAN or TBN, but wear looks good.
Long driving cycles rather than short trips? What fuel do you use, btw. One single brand? What climate and are you garaged?

Yes, long driving cycles. I live in Manhattan and have a house in Upstate NY. I go there every weekend. 130 miles each way. Don't drive it in the city at all. I always use 93 octane. Park the car outside.

Should be ok w/sludge then, but wear particles can be trapped in sludge & UOA shows low wear.
Particle count, TAN and TBN are needed for a thorough UOA. I'd cut the filter open if there was any question about sludge with short trips or whatever. You should be good though. The Pentosynth is working for you. I'd run a bottle of Auto-Rx, none-the-less.

All idling & light throttle is"beating"?What I call beating's soccer mom/ricer cold hammering it
I just have to stop this on 2 points. One is mixing different engine types into any analysis. You have to just compare a single engine over different driving styles. Second, are we defining "beating" as excessive wear? If so, city taxis have low wear rates. I have seen two studies on oil that were totally bogus because they choose such a low-stress test bed, taxis. 80% of wear is over start and warm-up. Add in sludge from short trips and I think I'm on firm ground.

You don't take cabs often, do you?
"Light throttle" is understatement of the year. They race from light to light, at least here in Chicago.
Also, idling...doesn't excessive idling polute oil with gas?
And finally, why bring up Taxis when in US at least all taxis are Crown Vics?
