Really interesting thread. I finally talked my buddy, and long time M guy, into buying a Porsche. I went with him to take delivery at Porsche HQ here in Atlanta on Friday of his 2018 Turbo. They said zero about a break-in period.... We drove it from Atlanta to Fort Lauderdale on Tuesday and while we did not beat it up by any means, we certainly took it over 4K a few times! One heck of a ride BTW. He should be joining Rennlist later today so hopefully he will post some pics.

PS: the whole delivery at Porsche was first class all the way and a ton of fun. Highly recommend.

Did my first oil change at around 1K miles. Ran the car normally but never launched it during that time. However, I did redline it a few times when I was getting used to shifting it manually. Revs come up so fast with this car in low gear. Oil analysis looked fine. Plan to stick to the recommended 10K service interval at the dealership and maybe do my own oil changes in between if the car starts to sit too long in between the recommended service intervals. Oil changes on this car is super easy to do yourself.

The following is a break-in technique that I got from 1999Porsche911 on the 997 Turbo board. He was very knowledgeable on past posts pertaining to car maintenance, CEL's and other engine issues, and knew more than I did. So I said what the heck
let me just go for it and break this baby in good. He guaranteed that your engine would not burn any oil and would be stronger than the average engine that didn't use a more aggressive break-in.
I had my first Turbo for 7 years and I never added oil to it once. I changed the oil about every 3000 miles and she ran like a champ. I then did a Softronic Tune. I expected to get some oil burn with this mod, but again nothing to add.

She ran great. I traded her in for my present 991.2 Turbo S. And as soon as the weather improves I will break this engine the same way. The following is a step by step technique that he recommended. Remember it's your car. Break it in the way
you feel the most comfortable. From my reading and research I just chose a more aggressive approach.

:Proper breakin must be done in the first 100 -200 miles and below is the proper procedure:

1. Always bring engine to FULL operating temperature before high revs.
2. Drive the car easy for the first 10 miles or so, varying the rpm's from 2,000 - 5,000.
3. Then, start bringing the engine up to maximum rpm's and letting the engine bring the revs back down by coasting in gear.
4. Repeat several times in order to create maximum heat in the cylinders.
5. Drive around at lower RPM's for several more miles, remembering to vary the speed of the engine every couple of miles.
6. Repeat number 3, 4 and 5.
7. Park car and let the engine cool down overnight.
8. Repeat all the above 2 more times.

Your engine is now fully broken in correctly and can be driven hard from here on.

The above procedure will also benefit engines that were not broken in properly. As with all engines, it is necessary to periodically drive the car to redline and engine brake back to stop to insure properly maintaining ring to cylinder wall fit.

PS. Hope this helps. Remember it's your car and you ultimately have to make the best decision.

Finally! I followed the book to the letter, but for two or three times when the pdk downshifted on me up to maybe 4500rpm. Had the oil changed recently in anticipation of the 2k mark. So nice to being driving it normally now. What a phenomenal car!
