I know this was mentioned before, but can someone please let me know where in the operations manual (what page or section) does it discuss the break-in period requirements. Thanks

It's under Safety and driving pleasure.

And no, this is not an endorsement of what's in the manual, just answering your question

you might like to read this write up as well...and below is the 2021 TTS owners manual



from the owners manual - what else do you really need

Found the break in info in the "under Safety and driving pleasure." as Wotaskd mentioned. Thanks. And than you to the others who posted the very interesting explanation by the Porsche engineer. Now comes the hard part. Driving 1800 miles (or so) at belwo 4000 rpm. Uggg

I have set myself the goal of getting 1,500 miles of break-in time before pushing. That's still hard for me though. I had my previous car for 3 years and by the time I sold it, it only had 1,900 miles in the odometer...

I went out and drove the car every night since taking delivery. Started to push it a bit around 1700 miles. At 2100 miles now and, ironically, haven't had a chance to drive it for a couple of weeks since i've been crazy busy.

Warm weather is here this week, I'd love to be able to try launch control after getting some heat in the tires.

I have tried to follow the recommended break in procedure. Unfortunately, on the way home from the dealer after picking up the car I was behind some mouth breathing ahole………..

I promise to do better.

If this is indeed true why isn't auto/start stop deactivated until the mileage is hit?

Joan Alcover

Probably because some owners who do not read the "owner manual" would complain that "auto-start-stop does not work on their brand new car"

The break in period has been a funny conversation for quite some time, but it has specifically been an interesting topic now that tolerances and manufacturing capabilities are very different then they were in the 60s and 70s, not to mention the advent of synthetics.

In a racing environment, engines are are tested on the dyno at various rpm speeds, then put on the vehicle for the a tune to be made to the ECU, and that is considered to be it, finished (by that time they have maybe the equivalent of 300 miles ? maybe never looked really) ready to go nuts, they aren't run on the engine dyno for 3 days straight at 3500 rpm to accumulate the mileage and get broken in...and a racing motor is significantly more expensive to build than a stock motor so if it made a difference to break them in with 2k miles every motor builder would have a lot of motors running on machines by themselves lol

Maybe the break in statements have more to do with liability of people getting used to the cars before they push'em, but i have a hard time believing it has anything to do with metal wear, i mean think of what happens in a motor at just 1k rpm, now think of that after the motor reached operating temp, you have cooling systems that keep the engine temp at 180-200, what more expansion is happening? expansion and stretch is directly related to stress and temperature, which is already at its peak once you get the motor up to temp and spin it a gazilliontimes at different loads.

Personally I think 500 miles is plenty, change the oil and have fun...if it wasn't the case they would void your warranty if you didn't follow those directions...and they don't.

I just got my car a few days ago and it's super hard to not smash the gas pedal on this thing. I've got 200 miles so far, so it's a long ways until 1800. First world problems I know.

Don't give them any ideas! With all the computers and data recorders in the car it'd be easy for them to see the max rpm with the associated mileage.

1865 miles of break in is nearly impossible for me. I will do around 1k miles for break in and observe the rpm limits, oil change around 1k and drive the car like it’s supposed to be driven.
I have a daily so like my old 911, I will drive around 3k or little more a year so break in of 1865 miles is more than half of my total miles driven per yr. Ya that is not happening

crazyrob

I've got about 1300 miles (lol in less than a month of ownership) and there are too many "screw it" moments that can occur. Every troll on the highway seems to want to egg you on lol.

My question is this in relation to the break-in period of 1800-2k miles (assuming you are in the break-in crowd):

Are we talking about short blips past 4000 rpm or extended moments past 4000 rpm? Being responsible is nearly impossible in sport mode, because halfway depressing the pedal down makes the beast lunge to over 4000 rpm.

Also I would love to hear more opinions regarding optimal mileage for that first oil change.
