How did you survive the break-in period??

Timely thread for me! I picked my car up last week and have just 300 km on it as it isn't my work vehicle. Staying below 4,000 rpm is killing me...so, I'm going to drive it as much as possible over the next few weekends to get the KMs up ASAP!

Break-in period? What is that?
I haven't followed it on any 911 I owned since 996 era. And I owned every generation. Of course I don't put 100K miles on them before I trade them or sell for the new generation, but highest mileage I have driven one was the 997 at 50K or so miles, no issues with the engine. Had the clutch replaced under warranty and also water coolant hose that broke under warranty. All the vehicles have been well. Most were taken to track within 2 months of ownership and seen quite a bit of track time every year as well.

I am of Germanic descent on both sides of what can be described as a family of engineers and can tell you that they would be be the first owners to question and disregard the ridiculous suggestion of an 1,800 mile break-in.
Best advice is to purchase a Porsche that is slated for demonstrators, PCNA beaters, or service loaners. I've heard that they all have special engines and running gear that does not require any break in what so ever.![Cheers](https://rennlist.com/forums/images/smilies/beerchug.gif)

This should help you with your Winter problem and thus your low milage per year and break-in problem.

C’mon…if you didn’t grow up in Chicago then you don’t understand the humor here. Anyone worried about the engine revs is a non issue if you’re stuck on Chicago freeways.
The “recommendation” for nice drives out of the city was mentioned.
Being from AZ I’m sure you can understand. You’re not going anywhere fast around Scottsdale, Chandler, Tempe, etc. When I lived there it was a pleasure to see the plethora of exotic rides idling and revving up and down the blvd.
Obviously the real joy from these cars is experienced when getting out and enjoying the open road.

xpost from a similar thread:
I find it interesting that people seem to think that break in is only about the engine. There are plenty of other things that need breaking in. For example I have never bought a clutch, transmission, or tires that didn't come with a break in period from the MFG. So unless you are experienced enough with every system in the car to ignore the recommendations, it might be wise to just follow what the people who are (Porsche) recommend.
Or don't, it's your stuff, neglect it at your pleasure. I will point out that OEM's have been crawling social media looking for excuses to void warranty claims for a long time, so proudly proclaiming you are not following instructions might be a self own down the line.

This couldn't be more misguided. People who truly understand mechanical systems would be the first to question this kind of blanket break-in advice. There are so many variables that aren't considered by this single-rule-based approach to break-in, that it'd be irresponsible for any good mechanical/aerospace engineer like myself NOT to question it.

The problem with break in recommendations is that they are expert opinions, but nobody has ever conducted a rigorous study to determine if they make a difference in reliability or not. It’s all just anecdotal

It's pretty wild to claim Porsche just pulled those numbers out of thin air. Just because you don't know why/how doesn't mean there isn't solid logic behind it. Even if lawyers / bean counters came up with it, it would still be based on some statistical analysis of actual data. Warranty claims = broken stuff, so to say it's to reduce claims isn't really invalidating anything. I don't want my stuff to break either.

So saying Porsche's consumer break-in instructions are overly conservative is not a wild claim. It simply comes from having a good understanding of the mechanical principles at work and also of the end users' willingness and/or ability to digest and properly utilize certain information. It's a great compromise that I would make if I were leading the show at Porsche or any other manufacturer, but it doesn't mean that it's actually necessary for the reasons you might think it is.
