When i went to the dealer to pick up my 997s, i brought up the topic of engine break-in (under 4000 rpm for first 1000miles) and they told me there was no such thing and i was free to red-line off the lot, all i had to do was go easy on the breaks to wear the pads properly. This contradicts what i've been reading on the other threads..... comments

 

We have had 3 997's and our dealers says the same - no break in required, just be sensible for first 1000 miles.

 

General rule is to vary the rpm speed during first 500 miles and don't redline it for the first 1000 miles or so.

I think it's prudent to do so. Most sales guys don't know better. I didn't see any thing in the manual which surprises me. I think MB has break in instructions in their manual but not Porsche. Maybe the engines are broken in at the factory.

 

I go redline out of the dealer the car runs better all P-Car engines are run @ the factory @ redline for 30 minutes before going into any car

 

Just don't abuse your car during the first couple thousand miles. Just because the engine is broken in, doesn't mean your clutch is.

 

here we go again

RTFM!

who do want to believe with a $100K car, the salesman? or the people who design, build, and warrenty the car? Give me one good reason why Porsche would print break-in rules if they were not necessary?


I am a doctor and every day I hear medical nonesense from people who think they know better than the doctors who spent 7 to 10 years to learn how to be a doctor, follow the break in rules

 

take it easy & gentle is always better in the beginning. break in doesn't all mean in engine only. it includes everything such as brakes, tires, etc...

because of my job i get to test drive lots cars. every Pcar drives very different in my opinion. bottomline is it's ur car & u want it to perform the best as it should be. don't need to baby it but certainly don't abuse it. to give u an example, what do u think of all rental cars or loaner cars u've experienced in the past? are they all feel crappy?

 

Manufacturers do those little window stickers and info to protect themselves I have owned over 20 cars and they all have never had an issue and I drive my car hard as I can from day 1. I was with my friend who has his brand new DB9 here for the winter from Canada and we have been redlining and racing all over we had it to 150 last night on 195 from Miami to the Beach..

 

i drive it the same way I drive my 3 year old M3. Starting from the first day I picked it up (12 miles). Basically, always wait til the engine warms up. Once engine is warmed up, I've taking it up as high at 5500 rpms even before it reached 500 miles. At around 900 miles, the breakin is over as far as I'm concerned.

My C2S still haven't had the need for oil, engine pulls hard and steady.

protect themselves from what?

 

Take two Vicodin and call me in the morning...I'm not a doctor, I just act like one.

Actually, not all docs agree on things. There are differences of opinion, but your notation about "salesmen" is noted. Even docs (and all other professionals) give conservative advice about things -- it's called CYA.

 

Very well put GD, it's a CYA thing. Common sense indicates abusing a cold engine isn't too smart but I don't believe these cars need to be babied. It's a high performance car...drive it hard from the get go. And BTW, can anyone spell warranty? The kicker is these cars are rapidly depreciating "assets" and most of us flip them relatively quickly.

 

Lets say encase something were to go wrong...it is a recomendation not the law

 

warm it up and drive it like you stole it

here's a good explanation as to why:

One reason why I buy new; you never know what you're getting when you buy used. Every engine requires break in and rpm variance, especially high rpm motors.
