It seems almost universal that all people on this site have to add some oil within the first 2000 miles. We need to ask a sales rep or mechanic is it normal to burn oil with the initial break in. And second is there a tie between how you break the car in and avoiding RMS issues. There seems to be a correlation. I hope to have a definitive answer soon.

As another point of reference, I kept the car under 4,500 RPM for 2,000 miles, and didn't burn a drop of oil during that period.
I had the oil changed at 2,000, and it appeared extremely dirty. Glad I had it done.
I broke my M3 in per factory recommendations (under 5,500 RPM for 1,200 miles), have driven it on the track extensively since, and after 36k miles haven't burned any oil.
Per my independent Porsche mechanic: RMS failures on Boxsters and 996s are not related to how the car was driven or broken in. Regarding break-in, he rebuilds Porsche motors differently for race cars and street cars, and recommends different break-in procedures for the different motors as well. While his recommendation for newly rebuilt street motors is not as long as the factory's, he does suggest a gentle increase of RPMs over at least 1,000 miles, followed by an oil change...with no harm if the break-in goes to 2,000 miles.

After just 14 days, I just hit 2,000 miles observing the 4200 rpm rule. Now that I am ready to drive we have a snow storm! That said, when I eventually get back on the road, what do you guys suggest re rpms? Can I immedialty go out and get to 6,000, 6500 rpms? 1st Porsche and loving every mile.
