How did you survive the break-in period??

1900 miles under 4k and now enjoying the car as it was intended. Note number two, don't buy a used car from this guy either. Who the **** do these "supposed engineers" think they are? Follow the manual and you will have a very happy long lasting car.

Sorry for making you so emotional about this. I'm not great at responding nicely to non-logical arguments and outbursts, so I'll refrain from interacting with you moving forward.
To anyone else who wishes to have a civil and fact-based or even experience/anecdotally-based discussion on this topic, let's continue.

Working my way through it but with the manual transmission, candidly not as painful as my last 992 PDK. Plenty of torque down low and love the engagement. I plan to follow the Porsche recommendations as with my other 992 cars.

Food for thought for anyone who's still interested in what actual mechanical engineers from various automotive manufacturers have to say on this subject. The themes are all the same. Vary engine RPM. Don't absolutely rail on the engine right out of the gate.

And one more very good one
And for the record, I don't advocate for the hard break in. All I'm asserting is that Porsche's procedure is needlessly conservative and that the occasional rev past 4k RPMs in the first 1875 miles is entirely inconsequential, especially after the first several hundred miles. I also assert that Porsche's break-in procedure is missing important details that are actually relevant to proper break in physics and tribology such as not pushing the rings against the cylinder walls too hard initially by operating the engine at peak torque and thus peak cylinder pressure too often (which can be achieved easily at under 4k RPMs mind you!).
I'm the type of person who has mechanical empathy. I love my cars and their engines, and I always want what's best for them. I put great care into maintaining my cars making sure to do maintenance and repairs the right way with the best parts. I personally would love to buy a car from someone like me who truly wants to understand and apply what's best for it.

Because the break in procedure is not designed to “wear in” the piston rings unlike rod bearings. Break in is to SEAT or push the rings out against the cylinder walls for maximum compression (which is maximum power) and no oil consumption. There is little if any wear involved this early in the life if the ring. The best method to seat piston rings is generating maximum vacuum until the rings are seated. The vacuum pushes the piston rings out of the piston groove and against the cylinder walls which is the goal. Poor seating of rings results in less compression (power), more oil consumption and gas dilution of the oil as the engine ages. You do not see the signs of poor Ring seating for a few years. The flat 6 produces maximum vacuum by GRADUALLY increasing and decreasing rpm between 1k to 4k rpm. WOT and high load does the exact opposite and causes a lack of vacuum so don’t do it until you are comfortable the rings are seated which the engineers who tested it (the experts with a lot more knowledge and data on this subject than you or me) say is about 1800 miles. I do agree with your comment about gradually increasing rpm psst the break in mileage though. 5k rpm max from 1800-2800 miles. 6k rpm max from 2800-3800 miles.
I guess the piston ring manufacturer gives porsche different instructions based on country of use, because the break in instructions vary by country.

@solidgranite now has survived his break in period of 1800 miles by reading this entire thread thru the remainder of the summer, watching endless youtube videos, and now his mission has been completed.

I am not going to lie, but the 1,875 miles is a rather difficult struggle and even after that is accomplished it is highly suggested that you gradually work your way up to redline. 🤦♂️
I always felt that the 1200 miles via BMW wasn’t that bad, but those nearly 1900 miles are a nightmare.

I don't see how anyone can go almost 2k miles under 4K. Practically speaking. I just had to pass a car with 150 miles on the car and immediately was at almost 5k.
If the recommendation was mechanically based why would it not appear in all markets? They only put that recommendation in for North America.
Careful and sound break-in according to my experience. I never get oil burning engines. Even on things like VW's 2.0T.
under 4k for 100 miles
under 5k until 200 miles
under 6k until 500 miles
under 7k until 600 miles
full range post 600 miles
First oil change 1k miles
Warm engine. Never lug engine in too high a gear during first 600 miles. Avoid short trips. Done and done at 600. One can condense this to a 200 mile schedule but I didn't want to make anyone faint, so I stuck with the protracted 600.

I greatly appreciate the above in theory, but sadly my OCD will not let it happen. lol By the book for me.
