How many people never go above 4000 rpm's during the 2000 mile break in. I would think a shot above that would be critical at least now and then but not holding it there. I have three other Porsches and each on was broken in the way. Easy the first few hundred then every now and then 5k and max of 6k. After 2 aircooled models and a GT never a single problem or oil usage. My new 991 with a 1000 miles has not used a drop. Time to push it a little. 5-6 rpm now and then while shifting only

 

Personally I stayed at 4,000 RPM's or under for the first 2,000 miles just like the owners manual states. Currently at 4,187 miles and my 991 is issue free and a joy to drive. Why tempt faith when you only have another 1,000 miles to go?

 

I didn't follow break-in per the manual. I didn't go crazy but I was certainly over 4K revs way before 1000 miles and more like 6-7K revs before 2K miles. Car has 14,000 miles and lease is almost up and no issues at all.

 

I would think that those of us that lease would drive it like you stole it from day one.
I for one own my cars and never lease.
After going to the Porsche road show, those cars are killed from day one. I asked the drivers from Porsche at the show. They all say easy for the first few hundred and then push then over 4-6 rpm's now and then. Not like they do on the track. They also said those cars are sold and never seem to have any problems.
I have to believe a run up though the gears now and then should be better for the rings. I would also say not until you have good oil and water temps.

 

Broke it in by the book. Change oil and filter at 2k, 5k and then every 5km 43000 miles and it does not burn oil. Enjoyed a treat at about 20k. The car seemed livelier as I believe it was not fully broken in or settled until that time.

Drive it like you stole it....yet another reason to avoid the purchase of previously leased vehicles

 

Agreed, I would never buy a rental or leased car.
Being in the rental business and overseeing 40,000 plus units I have never seen any problems with engines due to break in.
Brakes and transmissions are another thing.
Oil changes are your biggest insurance policy. Never go over a year. Time is just as important as miles.

 

Then again, there's always a car or so that's driven a little too hard.

 

break-in period? what break-in period? tons of thread on this. it's a sham. warm-up the car, drive it like you stole it. There is no mention of break-in period in the European manuals! Only for us Yanks. Go figured.

 

That's a new one. My guess is our warranty is better the the ones in Europe even though Porsche is still behind every other company in the US in regards to warranty? I still would not bet on it, I still take it pretty easy, 4-5 000 rpms now on then for a second while upshifting.My car had some miles on it even though it was new, who knows how the dealer ran it the first few miles.

 

I broke in my other 2 Porsches by the book. Doing the same thing on this one. I look at it like this, it's just not the motor, its the tranny, and everything else. I have had no problem on my other Porsches, but I and fanatic about The first oil change comes at 2k on a new car. Cheap insurance.

 

I've never broken in my cars. All of the Porsche dealers/ techs with whom I spoke about this topic advised me to "drive it like I stole it" from day 1. They just recommended to vary the revs. You'll get divergent views from folks on this forum, and there's no "right" or "wrong" approach.

 

Offcourse it is in the European manuals. This urban legend of it not being in there doesn't want to die apparently !

 

This is why I would do what Porsche says in regards to break in.

Agreed! And this is one reason why it's hard to buy a used one where you don't know its history.

Sounds good except for one thing, a friend at Porsche told me. Don't race or push it hard during break in,but its fine to take it to 5k give or take during shifts. Just don't hold it over 4k for long. He said for a split second as in a shift is perfectly fine. What they don't want you to do it hold it over 4k as if you had been on a back road and pushing it in a lower gear while getting engine temps high.
