So, any which way it goes, regardless of low mileage, I'll change the oil out on the MB, BMW, and the Porschi on an annual basis.
My logic is that even those these cars do not hit high mileages, I feel there is no harm in fresh oil and a fresh filter annually, get all the accumulated crap out of the engine, and what not.

Sorry, I don't see the logic in replacing (and disposing of) synthetic oil that likely will perform as intended for well over 15K miles. If your getting "crap" into your oil, that's a different story and a different issue.

With the diesels, and even with secondary filtration, the moment they go off road, the oil gets dirty.
When I drove the 996 to Edmonton and back this summer, and through several construction sites, it was most certainly a little dirtier, but not as clean as only city driving would be.

I attribute my lack of oil related failures - scored cylinders, bearing failures, grunge, carbon build up, hi temps, starvation, towing, suspended particulate, valve train, rockers, lifters, (in the diesels, 6.0/4 oil controlled injection) etc. - all things that weigh heavy on the performance of oil, and engine, on the fact that I am very religious about changing the oil.
I, as I am sure many of the forum have seen in the past, oil related failures are typically catastrophic, and very final. To me, it is just cheap insurance. That's all.

With that said, I still do it annually knowing it’s not necessary. I look at it as just giving up one fancy dinner for two once a year. There are many things that make me feel better even when logic says it’s not mandatory. This fits into that category. It wasn’t as big an issue when I was paying $0.86 for a quart of Castrol. At $7.50 a quart for synthetic, I would have no problem extending the duration.

You’re absolutely correct and I’ve seen studies that showed no discernible differences in wear between taxis that changed oil every 6k miles versus those that went 40k miles. I can’t put my hands on the link right now.

Maybe a NYC cab actually lives a decent life...?

I think that pushing the limit on oil will only come back to you at high mileage. You'll need a rebuild at 500,000 miles instead of 600,000 miles because of wear.
I can't see a catastrophic episode (go boom) because you changed your oil at 10K instead of 5K.

But by all means you certainly can do what ever you want. Cheers and stay safe.

And of course we all know where these dang oil threads lead...I think it's a better debate on the Bob's The Oil Guy's site.
