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.

To the OP: If it feels good, do it!

I've had the pleasure of breaking-in about 6 or 7 (I've lost count actually) new engines and always did an early change on the factory oil. When you pull that dipstick and see the ultra-fine particles as clearly as glitter on a Christmas ornament, the brain instinctively says "Change the oil now!". Heck, it looks almost no different than lapping oil with 1.5 micron grit. The finest polishing oil I'm aware of is available in 0.3 micron grit. Of course, metal grit is soft compared to AL02, boron or diamond grit.

Anyhow, I have a brand new Mazda 3 coming-up on 3000 miles. I can see the "glitter" in the oil. The 1st oil and filter change will be done real soon. I'll install a magnetic drain plug at this upcoming interval then, the next oil change and UOA will happen 6000 miles later. Factory recommended interval is either 5000 or 7500 miles so basically, I'm going to split the difference and go with that. Since I now feel I have reliable information about oil filters, my plan now is to change the filter every-other oil change. I've never done UOAs before so that will be interesting. I've always done early first oil/filter changes followed by factory recommended change intervals. This has not let me down over the last 40 years. I usually put about 150k miles on a vehicle then hand it over to one of my sons -who then drives it for another 70-90k miles. We've never had an engine problem -ever.

I look forward to seeing you post your progress and UOAs here. With your 110 mile commute we won't have long to wait...

Good luck and have fun.
