US can't math?.. I joke.. kinda.. German's being accurate.
This thread is specifically about the GT3.
What he is referring to is the 930 miles vs the 2000 miles for the GT3.
US can do math just fine, nothing about German’s being accurate.
I suspect US break in recommendations have nothing to do with mechanical engineering, and everything to do with money-grubbing lawyers.
My take in short; warm up very carefully, cool it down gently and stay away from the top couple thousand RPM.
Take a couple drives of 100 miles, don’t turn it off unless you are parking it.
I generally do above anyway at any mileage and seems to work great.
It used a lot of oil initially but that stopped at about 16,000 miles.
And if you track, replace plugs every 6000 miles, belts once a year.
This is an excruciating process. Everyone is like the gearing is so long — well not if you shift at 4000rpm! I slipped and went to 4200 a couple times. I wish they had some sort of temporary rev limiter you could enable.
Has anyone actually done the US break in recommendation of 2000 miles below 4k? Or are people doing the European “new” one?
Also, last question, I like to do an initial break in oil change. Better to do that at 1000 miles or 2000 miles after full break in?
Thanks to all - super helpful. Other than a few tire spinning overly revvy moments getting out of my slick driveway I think the break in has been at an appropriate pace. Here's the beast. It's Carmine but perhaps looks a little Guards red due to the lighting.

The car has 9000 rpm - taking it to 5000 the first 500 miles fine. From 500-1000 go to 6000. From 1000 to 1500 stretch to 7000. Go nuts from there.
I did first oil change around 1200. I felt the break-in was about over by then
There is no right answer. Do what makes you sleep better. I do not believe "drive it like you stole it" out of the box. I believe the first 1000 miles take it easy, and never on a new engine nor broken-in engine go above 6000 w/o oil properly warmed up- ~ 190 F
The new US books, now confirm... GT3 and GT3RS are good for 7,000 RPM for first 1,000 Miles. The GT2RS is good for 4,000 RPM for first 2,000 miles.
The above 'US Book' is outdated... 2018 model, which was the same my 2018 model read. After 100 miles, I started to approach 8k & 9k RPM, always shifting and driving away 'easy'. My car never burned a drop of oil.
For my '19 RS... I plan to stick closer to the 7K RPM for first 1,000 miles... but will look to around 500 miles let her 'experience' 9K. Then I'll change the oil...at the 500 mile mark as well and get the factory fill out.
Dave, fwiw, the factory Porsche driver that delivered my car in Leipzig told me that early oil changes that people do are a waste of time and money. He felt pretty strongly that it was not necessary.

Yeah, and with how good the oils are now a days... I believe it... just for me... it's such cheap insurance... give it a fresh 'rinse' of new oil and filter at 500 miles... and then I still end up doing every 3K miles or 1 year... whichever occurs first. (On my last GT3, I did it at 500 miles, 1,000 miles (1,500 odometer) and 1,500 miles (3,000 miles odometer). If you run race fuel at all... you'll notice quite a bit of 'lead' increase in your oil, as an FYI. I try to run my cars at about 95 octane, closer to what they're designed for.
I do it myself, and so it's 'fun' to get to maintain her, and show her some love.

Congrats, beautiful ride. Is the car on island? Can't imagine too many Tourings back home. Kaimuki is a stones throw from my neighborhood

Fair enough. We all do what makes us feel comfortable. For me, it's been first oil change after 5 track days and then change every 10 days or once a year. I have zero evidence to back up this method other than that is what I felt 'ok' doing. After what I was told in Leipzig, I may hold off on doing my first change until 10 days.

Yeah, the other good thing Leipzig told me last year... was 'let er rip' at 700 miles... which was a lot better than the 2000 they were saying back then!
You should do a Blackstone analysis... just to confirm your feeling. I think the biggest thing that surprised me about the Blackstone was seeing all the 'lead' in the oil, due to running 100 octane unleaded. Clearly the 'race fuels' are more like a 'low lead'.
On this one, I probably won't even do Blackstone... I now know what the fuel does to it... and I change it way to early to learn anything else meaningful from those test... it's $28 towards my next oil change.
