I guess it's a hit or miss in regards to how well the engine was assembled and it's overall design / efficiency.
If done correctly, there's barely any break-in material being shed and most is captured by the oil filter. No harm done if the initial fill is left in for the duration of the factory interval.
Now, if some absurd amount of silicon bits are floating around, there's cooper from oil coolers, piston rings are scratching themselves smooth against the cylinder walls, etc etc, then I would say it's better to drain that sand paper brew out early to help remove abrasive material. I want nothing but the purest, and cleanest of oil flowing thru my engines.
Some of you are funny though. You buy the best oil filter, some even install bypass filtration in an effort to keep the oil clean but then think it's ok to let the dirty factory fill remain in the block for months on end and thousands of miles.
That was me in the old daze, but when I bought my sig car in 05 I decided to simply follow the manual. My car specs 3000 mile OCI with M1 0W-40 as factory fill and on the filler cap. Today even though the 6.1 is a notable consumer mine is really tight, and even faster than when new with just shy of 100k miles on her. So no harm was done here.
I suspect that these days with modern cars the early change is not likely needed unless specifically recommended. Much like the larger oil filter craze, it's a "feel good" thing...
Absolutely agree that it's a feel good thing, and since I had the oil around and the filter was cheap, why not. I still intend to go to a 10k interval which should be easy considering the car is used for a 110mi daily commute with limited in town use. Car has a Lexus Care Platinum 6/120k warranty so likely whatever we do in the next 6/120k we won't be in for a big expenditure.
