When I see a URL with undisputed prooof the early change buys you anything I'm sticking to my 5K oil changes!
People saying to change your oil at 1000 miles on new vehicle.

I am what I consider an average guy. I work for a living and I try my best at making my stuff last. Growing up we had to, blue collar family, rural, work hard, take care of what you have. I'm on the edge of boomer gen and X. Being the youngest of all my family I grew up with older folks and a father that was born before the great depression. We were not rich, and not the poorest folks you have ever seen but we made things work anyway.
I have rebuilt engines so I would have something to drive. Get it cheap, make it work. It was a great education looking back, but I hated driving hoopties and used up vehicles. 305's, 350's, 300 Ford straight six, one iron duke, and even tackled a big block 454 once. We always changed around 500 miles after rebuilding.
Fast forward to today, The last new vehicle I purchased was the 2016 F150 in my signature. It physically hurt to wait to change the oil. I lasted till 1,936 miles before changing it. Then I changed again at 5,000 miles. I have tried to change every 5k miles since. Some changes going over but never over 6k and sometimes based on my schedule I have changed earlier for convenience sake.
I said all that to say this. Almost every vehicle I have owned has been used prior to my ownership, some well past 100k on the odometer before I ever turned the key. I have never had an engine blow, grenade, vent to the outside air through the block, since becoming a driver at 15. (transmissions are a different story) You can follow the manufacturer's suggestion about oil changes and likely be ok, lot's of people have. I just can't bring myself to do that. I follow a 5k oil change routine for all vehicles I own or drive. Your choice and your money. If I built it or drove it, I have never had a vehicle burn oil. I do my maintenance and keep my vehicles longer than most people keep their spouse now days.
Treat your vehicles how you want, but no vehicle has ever had problems from being properly maintained. The junk yard is full of those that were neglected. When I'm too old to crawl around on the concrete and do my own service then I'll get a home lift for doing my vehicle maintenance. ( if I can afford it)

So, 10,000 miles using 0W-20, on an oil diluting direct injection engine, with lots of short trips? You are free to do as you like, but I'll pass.
My Civic got its first change at 2000 miles, and it burns NO oil between changes (5k typically).
I changed the oil and filter in my new F-250 at around 700 miles, because I wanted too. Then I'm going to do 5k mile OCI regardless of what oil lift monitor system says.
NYH.

Make sense to do some filter swaps early which catches leftover debris, oil probably doesn’t care either way.

Exactly. Even if a filter only bypasses for one second at a time, there’s no way to determine how often it happens. Most likely not often or at all, BUT the fact that I had to write “most likely”, means we don’t really know. Add in a cold start, some debris in that filter, along with a wide open throttle situation - and it very well could enter bypass. Tossing that metal around a brand spanking new engine. Meanwhile if you just change it early, the metal is out. ProbablyBut one thread now has another debate over how often a filter bypass opens - so I’d rather toss one early - then step up to 20 microns and a known lube … Once in the life of a vehicle won’t break the bank!
(and I love to see the underside new) …
I wrote probably because we just don’t know, but why risk it? There’s plenty to chew on to argue to change it.
We just had the oil changed on the new Rav4 hybrid at 10,000 miles. It actually was still clean looking.
1000 miles is to long if you are doing it for initial wear-in metals and/or potential assembly byproducts removal.
But don't neglect the differentials/transmission and transfer case as they will also have wear in metals.
Good luck finding an official study over a lifetime of multiple vehicles. Facts we do know are oil filters are often times full of metal and debris from production and break in at the first oil change. We can only imagine what the filter doesn’t capture and is to small to see.
Do tiny particles that pass through a filter damage engines? I was under the impression that the answer is no.
I’ve done early changes on 2 of my last 3 cars, all Nissans. 2 altimas early and a 2018 rogue lease that I didn’t, because I was leasing. I bought the 18 during covid because it was to good of a deal to pass up. The rogue is at 94k and doesn’t use a drop so I don’t think there’s really a difference. My reasoning behind it was checking the oil and seeing metallic sludge on a paper towel, which very well could have been some assembly lube? Timely oil changes are more important than an early change imo.
Good question! We do have studies that show the smaller particles cause more wear. @ZeeOSix

I did the first oil change in my Corvette at 1100 miles and the UOA showed 2% fuel in it already and the viscosity was down to 9.3 cst at 100c. Copper was at 36ppm, iron was at 48 and silicon was at 124. There is no way that oil would have looked good if I had waited for the oil life monitor to count down to zero.
That’s all the proof that I needed to validate my decision at the time. There really isn’t a way to determine whether or not I extended the potential life of this engine but I’m pretty sure that I did not shorten its lifespan with the early oil change. That’s good enough for me.

Of course they don't do this. Sure an early oci won't hurt but it doesn't mean an engine is going to fail early or turn into a oil burner if you don't do it. BITOG represents the 1 percenters.
With regards to engines assembled today there's zero proof that initial wear is abrasive and has any impact on engine life. None. Nada. Zilch.
A UOA won't tell you either
So to sum the near 100 posts up, maybe, but maybe not, but you could, and it might benefit, but we don't really know, follow your owner's manual, or not, but you should change it early, except if you shouldn't, insert a few examples of people that did, or didn't, change early and have no consumption at 150k miles, and I think we know the truth.
FACT.
FACT.
I’m a dude and even I wash underwear before wearing. You should seriously question the judgment of anyone who doesn’t!99% also don’t wash new underwear before using it and live happy lives.
Diffs and Transmissions are far more neglected than any other fluid in vehicle, diffs especially!
I bet most people quoting the owners manual for a full first OCI, probably use some sort of “synthetic” oil in their cars.
Is there anything about using “synthetic oil” in the manual?
