US Car break-in poll...
#16
The only bad way to break-in a car is to take it to red line on a cold engine, which is precisely the way some new cars on dealers lots are abused. One of my sons worked summers as a lot boy many years ago at a local Porsche dealership, and he told me that he was surprised how many people spun wheels and accelerated to red line as soon as they got the Porsche off the dealer's lot. Just wondering if these cars experienced any problems after a couple years.

I hedge my bets. I follow US rules per the manual... for 1000 miles. Then all bets are off. I have a couple reasons, but one of the biggest is just flexing my self-control muscles for 1000 miles, figuring it's good for me, it's probably good for the car.
But 2000 miles? For most of us who only put 10,000 miles on the car before trading it, that's 20% of its life.
My current Porsche had 4000 miles on it when I bought it, so who knows what was done when it was new? I never think about it though.

The reason that's what this is, the factory puts that message in the US, but not in a lot of other countries. Then when Americans actually go to the factory, or talk to factory representatives, inevitably they are told there is no reason at all to baby the car. Warm it up, drive it as hard as you like. Its a Porsche.
Now as if that's not enough cognitive dissonance, there are a whole ton of solid engineering reasons, motorsports practices, and anecdotal builder experience behind a completely OPPOSITE approach, which is to run the car VERY HARD especially in the first few miles, following a very deliberate mode of hard acceleration and deceleration focused on achieving the best piston ring/cylinder bore seal. Seating the rings. That was the point of my Jake Raby comment. Jake Raby of Flat-Six Innovations, probably the pre-eminent Porsche engine rebuilder on the continent, does exactly this- personally - with every engine he builds. Since that is what we call an appeal to authority, a logical fallacy, I hate to even mention it. But its worth it just to amp up the cognitive dissonance to Spinal Tap Eleven.

I was just listening to Scott Adams talk about the recent Jordan Peterson viral demolition of Cathy Newman on YouTube. If you ever want to see an epic take-down of a snooty self-assured liberal ideologue, this is and I'm sure will be the gold standard for many years to come. Scott Adams talks about the cognitive dissonance Newman goes through and points out the hallucinations she has that have her saying he said things he never did say. The root of all this is he keeps demonstrating that she believes things she never did understand, but wants to keep believing, even though by the end of the interview its pretty clear she has no reasons to believe them. So yeah, cognitive dissonance can be upsetting.

I highly doubt you'll find any two people who followed the exact same break-in procedure or find a particular pattern. I find it hard to believe that even following the US manual, for 2,000 miles you did not let the RPMs go past 4000 RPM once (e.g. 4001 RPM), if so that is some serious exercise of restraint.
Same as some others, I *always* let the car reach operating temps before hitting the throttle hard, then try increase max RPMs as mileage increases (nothing precise about my break-in). I definitely exceeded 4000 RPM, even 5000 RPM even before 500 miles were on the car. Didn't hit redline for a little while.

I will admit I am a bit skeptical
That was exactly my issue after i broke in my 1st GT4, and said, bull**** 1000 miles is more than enough !!
My line of thinking
So if I answer the poll it would yes ,I followed the breakin and then my answer would be, no I wound not follow it again
But then again its not a 991 but rather a 981

My first Porsche was a Boxter 781 which I bought used with almost 1.800 miles so I never worried about engine break in.
My second car was a 991.2 Base Carrera Coupe and at the time of purchase, my dealer told me just to go ahead and drive it without worrying about break in. Actually, I received my car on Friday and on Saturday I went to a track day. Going to the track, our average speed was over 100 m/hr and we did several hard laps once in the circuit. I sold the car with 6.800 miles on it and never had a problem with the engine. Actually, the engine wasn't consuming oil at all and had a lot of power
Now I'm driving a 991.2 Base Carrera Cabrio which only has 620 miles. When picking up the car (first days of January), my dealer didn't mentioned anything about break in. Nevertheless, with this car I have decided to follow some of the suggestions about engine break in so I didn't reved the car passed 4.000 rpm for the first 500 miles. Now I'm slowly revving up the engine but still trying to keep it below 5.000 rpm. This
For the first couple of hundred miles, I could tell that the engine was very tight and that was confirmed by a very poor fuel consumption. As I put more mileage to the car, I can tell that the engine is looser, reacting faster and that fuel economy is improving. Big part of the milage has been done on a highway, with no cruise control and making sure to vary the rpm's. I never noticed this before in my previous car but maybe it was due to the fact that I wasn't paying attention. Now that I've been paying attention to the break in, I can really see a difference in the engine as miles start adding up.
Will this make a difference in my future engine life ? Really don't know, but since I'm planning to keep this car for a longer time, why take the risk and not do it ? It is difficult not revving your car to the limit and behave as a conscious driver ? For sure it is...... but is not impossible.
By the way.... I'm not from the US and the manual provided in my car doesn't have any mentions to engine break in. I have looked at all the manuals that were included in my car and none of them mentions anything about how you should drive the car for the first couple of thousand miles.
