Break the car? Bat or an angry partner would work XD.
No, I believe the break in period was 1200 miles but unsure how much of it helps compared to a real M. It's a lease so some might comment to just red line it from start but still do break in period, even for a lease. |

Congratulations. Good luck, enjoy and be safe. The break-in procedures are outlined in the manual.

I would trust engineers who put out the info shown above in turtleboy's post over CA's.

Hi, Jackodlum. Off topic but I just noticed that I've ordered virtually the exact same M340i spec as you (color, rims, shadowline, and calipers) great minds think alike as they say. I was wondering what your experience has been so far in how visible it shows dirt? It's something I never really factored in when making my selection. Mine is supposed to arrive mid to late June.

Take it easy for the first couple thousand, gradually open it up. At 17k miles now and burn 0 oil in between oil changes unlike a good majority of M340i's. But it's a lease so if you want screw it and have your fun from the first day.

I would avoid prolonged steady state revs on the freeway for the first 1k miles, vary by changing gear. Do 5-10 higher throttle (but not WOT or to redline) pulls then lift off to help seal the pistons. Gradually give it more revs up to about 1k miles. Then change the oil to flush the metals that come off during break in, and you are ready to rip full power. I ran my M2C in this way.
Always let the oil come up to temp before pushing it is the main thing, thrashing cold engines creates a lot of wear on the internals. |

I'm amazed that anyone at the dealership would say that. Was it before you'd purchased the car, or after? Dealers' stories tend to change after you've put your name on that dotted line, being very agreeable before and more rigid after.
