I also did a Euro delivery in 2002 and was told to just vary the RPM while driving. Other than that no limits.

 

I followed Manufacturer recommendations and even if its was overkill i feel subconsciously the car is faster for it.))

 

Thats what I like to hear, I don't have enough self control for the 2000 mile break in. Sounds like overkill to me, the car will be driven under 4200RPM for the first 500KM, then after that, its GO TIME!!

 

I have driven mine like batman in the final sequence of whichever movie you like from day one. Even snapped off 7k shifts and had it doing 110 on the test drive before I took delivery. Nobody has shown me definitive evidence that either method is correct, but one method is significantly more fun than the other : )

 

So is it what you expected? Waiting for pix!

A 2K "break in" period opens the door to lower warranty costs for the manufacturer . In some cases an owner may only drive the car 2K in one year so even in terms of time it cuts down the potential for hard driving repairs.

In my opinion ANY hard driving even on a broken in Porsche increases the cost of routine maintenance and gives risk exposure to warranty repair .

I don't think it's ever a good thing to push a car just for the heck of it . even though Porsche says its a track inspired street car the harder one drives it the more it costs .

So the 2K break in .. Is it real or is it simply a manufactuers way of placing an invisible leash on the drivers foot ? Each driver has to make that decision himself .

As for me ... 9 Porsches ..
a little lively driving with a properly warmed up car never presented me with a mechanical issue with any of them when they were new but i do tend to continue to pamper them even when they are broken in and have years of use .

 

I picked up a GT3 at the factory in 2003 (2nd US GT3 imported into USA). My son and I were on the autobahn headed toward Austria. The road was so perfect that we got the car up to 184mph (300kms/hr). I had that car for 2 years, put 19,000 miles on it and never had a problem with engine or tranny. I think I totally forgot about a break in period under the extreme conditions of an open autobahn.

 

I've broken a new car in hard and then one following the book. Seems the one driving hard (after fully warmed up) burned less oil and ran better than the one in which followed the manual.

I don't know for sure, if Porsche uses a break in type oil, I know BMW does. So I do change the oil and filter after 2,000 miles. Probably not necessary, but makes me feel good and is cheap insurance.

 

It's to reduce warranty claims Before the car hits 50,000 miles.

Nevertheless, I don't see the harm with waiting till 2,000, with an occasional warmed-up burst to 5,000 RPMs. And I certainly don't see any benefit to routinely hitting redline in the first 1,000 miles.

Although, we can surely count on someone to reply, "Oh, it's GOOD to break it in hard."

 

Dealer to track = 40mi. Done. Allan

 

Question: Even if not breaking in the engine is "harmful," what does that mean exactly? It's life goes from 100k miles to 60, 70 or 80k? Increased risk of catastrophic failure? I don't know the answer but seems to me it matters. In the same vein, I think making this decision has a lot to do with 1) how long someone plans to own the car and 2) how many miles someone drive a year. For example, if an owner drives 3 or 4k a miles a year for 4-5 years, 2k to break-in is a pretty steep sacrifice.

I recently drove my dad to pick up a new Subaru and before the sales guy handed him the keys, I asked him about break-in. He looked at me liked I asked him what color underwear he had on. It occured to me that it's a sports car thing. That (flat six!) Subaru engine isn't being broken-in and will likely live to 100k miles. (Yes I appreciate that Subaru drivers probably aren't revving the engine much). Still, In the 991's case, wouldn't you think that if Porsche has built such an impressively precise and efficient engine (33 highway mpg for chrissakes!!) that the engineering and build quality has also evolved to a level where break-in is irrelevant? That's definitely just a hypothesis but seems logical to me.

FWIW, mine is a launch vehicle that had a few hundred test drive miles on it when I purchased it. That kind of made my decision for me. I've since clocked 11k miles (in 10 months) with 15 or so track days and no problems whatsoever.

 

I personally fail to see the connection between the first 2000 miles and the span of the warranty period, especially if break in is not followed in all markets.

 

Are you sure that you got the units correct? Why do I have a feeling that it was 18k kms? Nonetheless even after the correct unit conversion, it's longer than 10k miles for sure.

 

Talked to my dealer service department today and the tenured mechanic said engines are broken in at the factory. If anything is going to go wrong, it typically will in the first 2K miles (not just the engine), so for safety reasons this is recommended in the US Market. He also said warranty isn't affected by going over 4200 RPM in the first 2K. He did mention driving at a consistant RPM for an extended period of time can get you in trouble when engine problems arrise. The onbord computer stores this information.

I've been doing good keeping it under 4200. Have 1300 miles now and am done!! Not going to go crazy, but am going to steadily increase my RPM's. Took it up to 5K today. It felt and sounded GREAT!! Only going to get better from here

 

yes, 18000 miles or 2 years. Anyway, see for yourself, this is a link to the German service intervals:

basically consistent with the rest of the world (minus US)

(NOTE: It's only list cars up to 2011.. but I assume it's the same for the 991)
