break in -i know i know...

porsche says keep rpm low for 2k miles - thats seems overkill
i was thinking keeping it below 4200 for first 500 miles

This also mean since i have pdk i cant put the car in sport plus becasue it basically red lines each gear

you guys really following recommendation for 2k miles?

Just no way i can not try out launch control for 2k miles..i want to try it on the way home!!!

It`s your car and your money, on other side if you sure no one test drove your car while it was at dealership - brake in does make sense, but if car was already raped by numerous 'testers' while at dealer - well, difficult to say.

I kept mine somewhat low for 2K. I did however exceed 4200RPM and did the occasional red line here and there after 1000 miles. Just didnt abuse the car. I tried LC at 1900 miles . I have only put 1 QT of oil in and am now at 3000 miles.

Obviously let the oil temp warm up before getting on it.

or those of you that didn't catch the latest Excellence, here's the meat of Bruce Andersen's Tech Notes on the age-old question of why are we in the US told the break-in is 2,000 miles...

As for break-in, I used to have a good friend who worked at the factory who would give me the straight scoop on all of these matters. When Porsche went to a 2,000 mile break-in recommendation [note - this is for the US market only], I asked him what that was all about. He said to break the car in like you were going to drive it: [Bruce's friend - Porsche factory guy] "The reason why we did increased the mileage to 2,000 miles is that, with new materials and lubricants, it actually takes this many miles to fully complete the break-in phase under light driving conditions. During this time, it may occur that the oil consumption is higher. To prevent complaints and to not alarm customers with 2,000 to 3,000 miles who may still have oil consumption, we had to raise the mileage. The gold rule is: the harder you push the motor after an easy 300-500 miles, the faster break-in will be completed. Bruce, the question is: Who really uses the potential of the motor these days with the exception of about two percent of 'track attackers' - whos cars are broken in after 500 miles?"

[Bruce again] Based on this, I'd say drive it like you stole it after 300-500 easy miles. I'd be willing to bet that if anything goes wrong with your engine, it will be something totally unrelated to how you broke it in. I'd follow the "break-in hints" in the owner's manual with the exception of the rpm limit; I would use the redline. Within the factory's "break-in hints," I would drive the car aggressively.

This jives with everything I've been able to discover on the subject. The only manual in the world that has 2,000 mile break-in is the US one, yet it's the same car everywhere. Reports were that the break-in was extended due to possible complaints from US owners that don't understand high-performance engines and their break-in process (oil consumption possible).

Just thought those that don't get Excellence might enjoy the read...

I say drive it like you stole it, or at least intend to drive it. You don't seem to keep you cars for long periods of time, and by the time the warranty expires, you won't have the car anymore.

Every car when it leaves the factory is fully tested to red line for any and all issues. There is no "best way to break it in", really just things not to do.

Don't do lots of highway miles before 500 miles, the constant RPM will not break in the piston rings or cylinders correctly.

Don't flog it. Possible the worst thing you can do is underun the engine.

Don't race it to red line every time. This could be worse than flogging.

Do drive it with varried RPMs on a regular basis.

Do drive it like you stole it after the 500 miles is thru.

Do have fun with you car and dont leave undriven for to long (this is best for you and the car!)

i put 500 miles on mine and then started cranking. its consumed about 3 quarts of oil and i have about 3000 miles on it now. It just gives me another excuse to go visit my dealer that tops her off and treats me like a king.

I was easy on the engine for around 600-700 miles, than I started to redline it. No problems so far... (knock on wood )

Definitely helpful information, thanks!

i've heard if you baby the car too much too early, then the ECU gets "used to it" that when you try to drive the car hard, it won't give you as much performance as if you drove it like you stole it from the beginning which requires an ECU reset. Is this completely a myth? I've kept it under 4K RPM under 1K miles, then under 5K RPM under 2K miles. would i need an ECU reset?

thanks - as you can tell, I am mechanically challenged (amongst other things)....
