Edit: The recommendation for the 1800 mile sub 4,000 rev break in period is indeed there in my uk manual. I couldn’t find it with the search function. That’s my confusion resolved. Same requirements on European cars.


See a lot of chit chat on here about the 1800 mile sub 4000Rpm break in period so when I picked up my UK delivered Targa 4 GTS I specifically enquired about it.
My dealer told me there is no break in period and he’d never heard of it.
There is no mention of a break in period in my online manual in the UK MyPorsche app.
I can only conclude that the break in period is to satisfy some sort of legal warranty requirement for US based customers. Same cars, same engines, different warranty rules.

Oh it's there and it is also bound to cause spirited conversation here as always. My dealer didnt know about it either. It's in a place in the OM that is not intuitive:

Safety and Driving pleasure > before driving: impotant information regarding yourPorsche


Enjoy your car...but be sure to run-in the engine properly if you plan to. keep it

And let the debate on the definition of “properly” begin!

Run-in period is only for "GT" cars. Otherwise, there is no need to be mechanically sympathetic for any new machine, for any reason, ever :

Obviously the same engines with equal tolerances in the UK or any other non-breakin territory.
I've owned more sports/performance cars than I can remember at this point and have bounced every one of them of the rev limiter inside of 50-100 miles and never had a problem with any of them.
The vast majority of guys who fist pound about gingerly "breaking in" a new car have never changed oil or a tire. Do these automotive experts think manufacturers provide dealers cars with special engines and drivetrains that can be redlined from day one for test drive purposes. Do these cars just blow up and get swept under the rug.
The Dudley Do-Rights who chastise anyone that dares to question gospel from the owners manual which oddly isn't necessary in other parts of the world for some unknown reason know little to nothing more than what they have seen glancing at car magazines.

The English do everything backwards. I think you're not supposed to let the RPMs drop below 4,000 for the first 2500 kilometers.

Break-in has nothing to do with short term engine failure. It relates to long term engine viability and avoidance of premature failure - what happens at 50-100K miles.

@Marcha it sounds like your dealer is setting you up for Porsche to void your mechanical warranty. Good luck your dealer is an idiot.

Same experience. Dealer (in US) told me no break in is required. Also took this forum to tell me where in the manual is was discussed. It is organized weirdly and the search function sucks.

FWIW, different company. Different engine. Different build and break-in/run-in procedure. Still an engine. Still a break-in/run-in procedure...to get the metal shavings out of the break-in/run-in oil, et al:

A break-in period can't hurt, and will probably do some good. On engines this expensive, better safe than sorry.

I'm not sure I'd consider any car dealer as the last word on stuff like this.

My SA told me the sport repsonse button will put the rpm to 4000 instantly and that i should try it out on the first on ramp. Also gave me a couple good locations to try out launch control. USA.

I saw a video on Porsche engines somewhere and it said metal shavings are a thing of the past with new and better milling and CNC machines to produce the components. Nowadays it's a matter of the various adhesives used that leave residue in newly built engines that break down over time but have "replaced" metal shavings and the sort.

ipse dixit

If you don't plan on keeping the car beyond the OEM warrant period, there's no need to do a break-in, regardless of what the manual says.
