Engine Break-in, Inconsistent Info in Owner's Manuals
Was fortunate last year to get an allocation for both a PTS GT3 Touring and a GT3 RS. Just by luck they both have production dates (stamped on the door) of 10/18. I don't remember exactly what my previous GT3 and RS had stated in the manual about engine break-in but seem to remember something like 1,000 or 1,500 miles and keep it below 4 or 5k rpms. Have seen different info in a couple of threads here so I decided to open my manuals since I'm getting close to a 1,000 miles on the RS.
Took a photo of both manuals and the info is on the same page 14 in both.
Completely different info and reccomendations. The RS is a MY 19 and was delivered in late December. The Touring is MY 18 but it was delivered until late January.
In the GT3 manual: 2,000 miles, don't rev over 4k.
In the RS manual: 1,000 miles, don't rev over 7k (applies to GT3 RS and GT3)
Surprised a bit at the inconsistencies considering it's the same motor. Imagine a little common sense would solve the discrepancy - don't mash the pedal until the oil is hot and don't wring it out until you put some miles on it.

The guidelines were revised with the 2019 cars. I thought some people with late 2018 cars also had the revised manual.

In that case, lawyers finally have a subject where they made things easier and not harder! the new break rules make it so much easier, perhaps PNA realized no one was following 2K miles and under 4K revs so they changed it to something more realistic.

I was told at the factory 5k RPM cap for 1000km, warm up gradually. I would be surprised if they have any good empirical evidence that show significant differences in wear among the various guidelines. Be reasonable, make sure the engine is good and warm and vary RPM for first 500-1000k miles. After that let er rip...

Euro delivery and have the same manual as your RS. This matches what’s in the manual for cars sold to European customers according to my European friends who posted on my Euro delivery blog. I take this as the ‘official’ Porsche factory recommendation.

Finally got to 8250rpm burst now at 1250miles on odometer... Yowzer...
I was starting to think maybe time to move on to something else but kinda different beast beyond 7krpm.... possibly a forever keeper! lol..
GT3RS=wife?

Okay to add to confusion...my GT3 was delivered January 2019. (also in Tennessee). Vehicle completion 11/30/2018.
The manual matches yours labeled GT3 RS

So all of the really low "Delivery miles" GT3s and GT3 RSs have just low rpm driving for the few hundred or so miles on their clocks? Well I sure think that is true. Cough cough.
