Yeh, I also was told by the dealer "don't worry about it" when asking questions about break-in. And at the same time they were handing me an Owners Manual which clearly states (for 1998 318i):

For the first 1250 miles do not exceed 4500 RPM. Also there may be something about not driving at a constant speed (don't have the manual handy right now).

So, the car now has 2,900 miles and I can still feel additional power developing as it breaks-in. I also haven't exceeded 5,500 RPM yet. I did keep it below 4,500 for the first 1250 though. The info I have says they're not completely broken-in until 8-10,000 miles.


: : Just curious, what are the procedures for breaking into new Bimmers? Thanks!

: I've been reading in that since new bimmers now come with BMW's synthetic that the breakin period is much longer than the old traditional 1000mi. I've heard varying lengths from 2000 to as much as 5000.

: Since my shiny new 323i isn't even built yet, I don't have an owners manual to refer to. Can someone who does have post what BMW recommends?

: BTW, apparently some dealers are stating that *no* breakin period is needed. Crazy, I say, but who am I to really know: I don't design BMW engines for a living.
