Not sure what to believe. I've got a Pal that has had a few 911s and never broken them in...........but hasnt kept them very long. I know it can't hurt so why not do it by the book I guess.
Because it's boring, and that's not why I drive a 911. I cannot keep it under 4000 rpm all the time.
RTFM!
I cannot understand why individuals would believe 'Institutional Knowledge' rather than written guidance in an Owners' Manual?
I do understand that differences exist in what different areas of the World have for guidance in this area.
My Volvo's have no break in period and no oil change until the first Service Interval.
But Porsche engine is a different design and specification.
Until my first and subsequent DE events, I was sure I would suffer failures from using the Porsche's on Track.
I followed the Owner's Manual for break-in,
but could find no definitive guidance in the Manual nor from Porsche NA or my Dealer on changing oil before the first period for a DE event or waiting until Service Required.
So I have the oil changed before the first DE and at subsequent intervals based on my Engineering Judgement.
Best I can do.
Since I am not privy to Porsche Engineering Design and Manufacturing Specifications. Oil Sampling and Analysis are not going to do me a great deal.
But if no DE, I would not change and follow the Owner's and Maintenance Manuals.-Richard
BTW 20K miles on the 2013 Boxster and 14570 miles on the 2017 C4S.
No problems or oil usage noted.
Just so y'all understand - engine break in is a function of the number of revolutions, not miles. So if you keep your revs up and use plenty of engine braking, you can break in your engine in less than half the miles Porsche recommends. They (because of the Greenies) must assume you are cruising most of the time at 1400-1500 rpm. PDK will do that in normal mode. If you select your SC and gears so you are always cruising in the 3000s, your engine will break in in less than half the 1800 miles recommended. And always use plenty of engine braking. It's way better for the engine, as it sucks oil up the cylinder walls for better lubrication, and prevents scuffing. Turn off that stupid Greenie switch that allows coasting and better fuel economy. This is a Porsche, FGS. Save that idiocy for your Toyota Prius...
I don't see anything in the 2017 Owner's Manual that requires a break-in or sets any hard limits for the first 2,000 miles. What the manual provides, verbatim, are "break in hints" and "tips" to "obtain[] optimum performance."
Personally, I'd take it easy for a few hundred miles, and wouldn't track a brand new 991 until after the break-in period, but I don't see anything that even implies that exceeding 4,000 RPM would damage any part of the car or reduce longevity of any component.
It simply says these are break in hints and tips to maximize performance.

This topic has been beaten to death numerous times. Do what you like, either way the engine will not explode and your car will not be a piece of ****.
They may be hints and tips but the verbiage used to preface each one; "Preferably," "Avoid," "Do not," "Never," to me indicates the degree of adherence each tip requires. I just passed 2000 miles (followed the tips) and am now enjoying the car worry free should something go wrong, to each his own.
I broke my GTS in on my drive up PCH from Palm Springs to San Francisco. And by break in I mean high revs and lots of smiles. @15k miles now with no problems. Runs fantastic.
