Just finished up at the PEC-Atlanta

On the track I was driving a 992 TTS (ordered/delivered 992 TTS) and noticed the TTS car I was driving had 700 miles on it.

during the skid/slalom/launch/donut portion we were running the car well above 4K rpms, and bouncing off the rev limiter (the cars were fully warmed up).

I asked the driving instructor why we were running the cars that hard when in the owners manual is says to have a 1800 break-in and keep in below 4K rpm.

He said what they do is drive them easy for the first 100 or so miles, then they put them on the track for the customer driving experience. They’ll then sell the cars to dealers as CPOs at a later date.

So if anyone gets a 992 TTS with truffle brown interior with more than 700 miles as a CPO, It did not follow the owners manual break-in procedure.

This one has been discussed before. In the US the owner’s manual calls for the long-winded break in process. Buy the same car in Germany and the recommendation does not exist. Many believe that it’s due to the litigious nature here in the states. I drive mine gently for the first couple hundred miles to let everything settle in and then progressively increase the performance of the car. Many here do the same. My cars have always run well and proven to be good long term drivers. Life is too short - enjoy every mile :-)

No care. At all.

I did PEC Atlanta when they opened and I did drive 718 S , GT3 and 911 Turbo, all had less than 1 k miles on them
and instructors were encouraging me to push as I hard as I can
we did have some extra time and I remember launching the 718 S like 20 times a row , and the instructor kept asking me if I want to do more .

Yep. I think the break in procedure is complete BS

Is that true the breakin process is only recommended in the US? Didn’t know that.

Yes, the manuals are different. My opinion like the other poster is we live in litigation hell ..........driver buys a high speed car and floors it day one which zero experience kills him or herself you’re in court. They figure you drive it 2000 miles and learn the car you don’t kill yourself, and you can’t argue you didn’t know post 2000 miles. Many will argue this over and over ............all my Porsche’s GT cars I drive a full tank of gas a varied speeds a mix of high way and street all below 7k RPM, and after have fun. My buddy took delivery of his 997 GT3 4.0 in Germany with a Porsche driver on the track less than 10 miles on the car and they going ***** out. Engineers said have fun no problem ............ again not giving instructions but MY view point on this saga of a topic for years. Funny Mclaren’s have no break-end required so I do think it’s a lawyer up clause.

If it really is needed Porsche would program it in. The mere fact that they don’t and that they take the ‘risk’ with their own cars, then sell them on through dealers - with warranty - should tell you everything you need to know.

Found this. Dealer saying the break-in period in the owners manual is too conservative.

Necessity depends on the objective. If the objective is to maximize longevity and performance it might produce different necessities than if the objective is to keep reasonable performance through relevant periods of warranty. So European documentation and anecdotes regarding track use of new cars support the latter but not necessarily the former.

Thankfully, this thread hasn't taken the turn (yet) towards the dudes afraid of everything that baby their cars for thousands of miles then pray to them after parking them safely back in the garage.

Anecdotally, BMW M5s are notorious for burning oil - from e39, to e60, to f10. You can tell the ones that were broken in using the lawyer's procedure. They burn the most. I drove mine like a bat out of hell off the lot, after warm up, running up and down the rev range. My cars never asked for a drop of oil. Has to do with sealing the rings, apparently.

Progress up the rev range over two tanks of gas. Always wait til the car is warm before you hammer it. Done.

No, it's not.

As far as I know, PAG recommends some sort of break-in period in their manuals in every part of the country. What is different is the type and duration of the break-in. Some are shorter in length (2000 km versus 2000 miles), or different type (i.e., max RPMs and what-not). But regardless, Porsche always recommends a break-in period. The key is the break-in period is a recommendation, not a requirement (like oil changes).

But let's be clear for a minute before someone jumps down my throat by quoting from the manual. There is a difference between the car requiring a period for the parts to "break in" (i.e. in Porsche speak "for the parts to be run in with each other") and whether the user is required to give the car that period to break-in. PAG says the former is required, but the latter is simply a recommendation. This is why those guys and gals at PEC ATL or LA will simply run the car from the get-go as if the break-in period is simply a recommendation, which it is.

That said, if you ask Andreas Preuninger, head of Porsche's GT dept., he will will recommend a staggered break-in procedure, along these lines:

Co-worker in The Netherlands just told me the dealer said 1000km for break-in and the official manual says 2000km. That’s 600m and 1200m respectively.

Last time I looked the manual in Germany says break-in period is 3000 km.
