How'd this turn into Bob the Oil Guy forums? 
Most of the automotive world seems to agree with Oliverk and GT-ER, including myself. Of course I do UOAs at each change to determine my own OCIs. And the lab doesn't do a smell and taste test, but an actual TBN comparison to the virgin oil. imho, it's the best way to monitor oil and figure out OCIs based on your own environment. But what do I know? And the aviation industry probably doesn't know anything either (the main clients for UOAs.)
Each to their own, but this argument by certain cavemen will go on until we're in all in electric cars. And then it'll be about when to change the carbon brushes, lol.
fwiw, this is from an oil company (that would prefer you actually buy more oil): "Against conventional wisdom, engine wear decreases as oil ages to a certain extent, which means that changing your oil more frequently actually causes engine wear; these findings were substantiated by studies conducted by the auto manufacturers and petroleum companies, leading to increased drain intervals"
Anyway, do what makes you psychologically feel better. It's all good.

Seriously? How so? Oil lubricates your engine, how will it smooth out its operation? I assume after you wash your car, after it has been dirty for a long time, it runs smoother too.
I am with Oliverk on this one.I've seen rod bearings spin and even seize causing engine failure on a number of cars not necessarily due to the type or quality of the oil, but due to not being diligent with checking oil levels and the quality and/or conditions of the oil (thinning due to fuel leaks, etc).
Checking oil levels, and the condition of your car, and doing maintenance, is all expected for the car to last a long time. I don' think anyone would argue that.
Of course.
