I tried searching, but couldn’t find anything. I’m sure this topic has been beaten to death . If there is a link to a previous discussion, I’ll take no offense .

I recently took delivery of a 24 Cayman GTS and the salesman told me the break in baby period was a tank of gas. After that, he said stay under 6k RPM for the next tank (500sh miles), then gradually drive it like your going to through the 3rd tank. Stay off the track/rev limiter until you’re over 1k miles. I took the advice and have the car over the 1k mile mark about 2 months in. Reading more forums and talking to other Porsche owners this advice seems to be a tad aggressive, and one person told me that Porsche will void your warrantee if the car isn’t kept under 4k rpm for the first 2k miles…?? That seems incredibly excessive, but maybe it’s true?

Zero track time, zero rev limits, but I have enjoyed some spirited canyon roads so far. Hopefully this didn’t hurt the car or void the warranty :/.

have any of you had any real life experience with this? Thanks in advance, and no offense if I didn’t conduct the search properly

Cool salesman - he personalized the break in for you - kind of gave you a breakdown! I think it's fine especially if you followed it so far. I go for incremental rise in rpm's for 1500km, do the first oil change then can go to redline. All with engine warmed up of course. Get ready for a lot of other opinions.

If there's not a diagnostic in PIWIS I doubt they could check unless you ping the limiter. You're doing about what I did when I took ownership of mine (with its new engine). Only additional thing would be to change oil at 1.5k or 2k miles to get the break-in metals out sooner rather than later. There are some break-in threads in the other rennlist forums that discuss the topic:

Thanks for the response! The salesman was actually a really good dude and also a Porsche driving instructor. He seemed to know what he was talking about, but he definitely didn’t tell me to refer to the owners manual or anything regarding warranty 🤷🏻‍♂️

My German Porsche dealer's technical advisor told me not to change the oil. I asked if it it was advised at 3000 km. Metal parts seem to be mimimal with modern engines.

I followed this procedure and started driving full throtthle and redlining the car around 1500 kms's https://rennlist.com/forums/991-gt3-...l#post15498988

You cannot void your warranty by not following "proper" break-in procedure.

Regardless of your views on break-in process. It's not a requirement by any means. Just a strong suggestion. There are plenty of people out there that do an aggressive break-in process (drive it like you stole it) Obsessed Garage on Youtube is a big supporter of not needing to break-in his cars and he's a huge Porsche lover and owner, and there are a lot of people out there who believe you need to get to 2000 miles before doing ANYTHING with the car. And the hundreds in between.

The reason why it seems like this question is unending, is because theres not a single car manufacturer who can definitively tell you if you NEED to do it or not. Sure it's in the manual, but it's never been a requirement. Because if it was, car manufactures would do it themselves (which they do) and not leave such an important process in the hands of the general public.

End of the day, just do what is comfortable to you. Personally i've done everything from babying it to 1200 miles, to incrementally increasing RPMS to 1500 miles to just driving it without a care in the world, and i've never had an issue that could be related to my break-in procedure. With my incoming BGTS, i plan on taking it easy for my first 2 tanks of gas with incremental gains in RPM, and once i hit that third tank of gas i'll start driving it how i would just normally drive any of my cars.

Here’s what I’ve been doing since AP stated this about how Weissach breaks-in their own GT cars:
I interpreted that to mean the following for the 982 GT4:

• 0-62 mi (0-100 km): Max 4000 RPM
• 62-186 mi (100-300 km): Max 4500 RPM
• 186-311 mi (300-500 km): Max 5000 RPM
• 311-435 mi (500-700 km): Max 5500 RPM
• 435-559 mi (700-900 km): Max 6000 RPM
• 559-684 mi (900-1100 km): Max 6500 RPM
• 684-808 mi (1100-1300 km): Max 7000 RPM
• 808-932 mi (1300-1500 km): Max 7500 RPM
• 932-1056 mi (1500-1700 km): Max 8000 RPM (Full throttle after first oil change; ideally send off sample for documentation)

Then here’s what the manual for the 992 3RS says (which I’d consider Porsche’s latest guidance for high RPM motors):

I am going to prob do under 5k for the first 500 miles, under 7 for the first 1000, I was expecting to do an oil change at 1k, but it seems that it is not really talked about and recommended. after 1k miles I will enjoy it.

Xxyion

i personally liked doing an oil change at 1000 as i feel like it gets rid of any new car excess, kinda like flushing out a water filter when its brand new. I'm sure it'll all in my head but i do it for peace of mind.

Yeah, 2K-mile break-in definitely sounds excessive. Some of the methods described above sound a little aggressive, but engine should be fine. Just remember the 4.0 is not a GT engine, so I wouldn't follow the recommendation on those, but to each his own, of course. Good luck. Wish I had a car to break in, but it'll be a LOOONG wait. Ha ha. Oh, and I plan to change the oil before 2K miles for sure as well.

Riz

Just don't drive and park it in a bad area unattended because the break in will be done very quickly. I think we answered the OP's question so can move on.

I chose to do what the manual said, kept it under 4k as much as possible and changed the oil a little bit before 2000 miles because I had a driving event planned for right around the 2000 mile mark. Changed the oil a few days before that event.
