BTW, I never did understand why manufacturers recommend a break-in period at all. Machining tollerances are much finer nowadays than previously, and they are certainly much more precise than detroit motors of yester-years.
The whole point of break-in is to get the rings to seat in the bores asap, promoting seal. Slowly breaking-in the motor goes against this principle. In fact, constant RPM break-in (highway driving) is probably not all that effective. The motor needs to run through its RPM range in order to stretch and seat the components to hit it's limits w/in the allowable and intended range.
I know of way too many people (as well as race shops) who break-in their motors quite oppositely, whether it'd be cars or motorcycle engines. While each has their own way, they pretty much run the car hard, and through it's rev ranges w/in the first few hundred miles, then change the oil. I too have broken in a motor that way on a built 1.9L Turbo motor (380rwhp). Never had any issues with them burning oil.
Just some food for thought...

Yo Lou,
I really don't know the answer... perhaps the break-in period was for purposes of other than seating the rings?
All I know is that many people I know institue their own break-in rules of driving the **** out of their motors when new. Talk to some car and motorcycle engine builders, and many will tell you the same.
Whether the rings seat properly or not usually takes place within the first few hundred miles. After that, it really doesn't matter.
Break-in was much complicated in the past when the tolerances were total ****. Now, honing processes are more refined, so much so that they can run synthetic right out of the box. Some manufacturers do add modifiers to the oil to help aid in seating.
You are absolutely correct in that the common process in the past was to use regular oil for break-in, and syn from there on. So, Porsche must feel confident that their rings will seat despite running synthetic from the start.
Personally, I don't understand break-in procedures unles it's aimed for purposes other than seating the rings.

Perhaps a gentle break-in helps the engine last longer, but a hard break-in frees up more power early, but at the detriment of long-term engine life?
Since Porsche would rather your engine last longer (makes them look good), that may be why they tell you to break it in for 2,000 miles (which seems extreme to me). And I thought 1,200 miles on my M3 was bad!!!

On a different note, I bought an Integra Type-R in 1998 and it was the first "quick" car I ever bought. When racing other Type-R's I would always win, or at worst it'd be dead even. And my car was stock. When I modded it, I was taking out cars I shouldn't have been able to take out.
So later my Fiancee got a Mercedes C-Coupe and I told her to follow the break-in procedure. Since it was her first car and it was STICK (I was teaching her), I drove the car for most of the break-in period. IMO, I feel the car feels slower than it should be realative to other cars.
So my Fiancee still has the car and then I get a 2002 BMW M3. I followed break-in religiously as it was my first "high-end" car per se. My conclusion is that this car is ALSO slower than I expect it to be. Sure, it's faster than most cars out there (my favorite kill was a 996 C4), but I just feel like it should be faster than it is.
The only car that ever felt "QUICK" the whole time I owned it was the Integra Type-R. The funny thing is that I ragged on that car from almost day 1 since I was young and addicted to speed with little responsiblity at the time.
Another reason I did this with the Type-R is because someone I know said they ragged their Type-R from Day 1 and it was faster than other Type-R's. Since I sat in the guys car and felt it was very quick, I followed the same path.
Since I'm taking delivery of a 2004 Turbo Cab at the end of next week. I don't know if I can resist getting on the gas for 2,000 miles. I think I'll go 600 miles or so before I start getting on it. Plus, I don't plan to keep the car forever so I can benefit from the extra power while I own it and leave the "long-term" downside to the next owner.
