How did you break-in your m car?
I am only 425 miles on the clock. I ain't no saint.
I will talk more about my travels thus far but tell me how well did you do? |

I never exceeded the rpm requirement or did WOT pulls but besides those two items I varied the shit out of the load, took it to the mountains and drove it pretty hard under the 4500 requirement Then dyno'd it at 2000 miles for its first WOT and it did not blow up

Vary the load as stated above. Perform engine braking also.

Varied RPMs as stated, kept (mostly) below 5K rpm and I only did one kickdown on the freeway but that only brought the RPMs up to about 5500.
Dealer reminded me they do a run up on these cars before the leave the factory and mentioned the only thing that really needs to be broken in is the clutch pack in the diff. That's why they change/inspect that fluid before they flag it as broken in and the car can be driven the way it was built to be driven. |

2 minutes after leaving dealership I hit red line on 1st, 2nd and 3rd
I did it same way Motoman recommended years ago, i did all my previous cars and motorcycle this way: - proper warm up - high load acceleration to red line and deceleration in multiple gears - avoid constant speed till first service - oil change at 40km and 1000 km regular driving after first service... |

Normal city driving is a good enough brake in. What you wanna stay clear from is long distance highway driving where the rpm's don't vary much for extended periods of time.

Still breaking it in. I'm doing as many backroad drives as I can, under 5500rpm. Once warmed up I'm getting on it a bit, probably 80% throttle.
In the rain trying to avoid triggering traction control as I think we're breaking in the diff more than the engine.

It doesn't take much to break a motor in these days. I don't know why folks still follow the old methods from the 70s and 80s. Definitely not suggesting you bounce off the rev limiter in every gear and slam gears as hard as you can, but rev her up and use engine breaking like stated above. The "don't drive for extended periods at the same engine speed" is good advice. Just change gears, yo.
Oh, and I know one of you said "break her in on the dyno" as a joke, but that's actually a great controlled and safe way to break an engine in. How do you think the guys with purpose-built race cars do it? Last edited by M3 Alex; 12-05-2019 at 10:45 AM.. |

Now I will concede the procedure in the manual might not the best way, it may be written by lawyers and not engineers, but I am not confused why people follow the directions in the manual. |

Completely avoided freeway drive.
Varying RPM upto 4.5k with varying speed (driving in local will let you vary spped). Keeping it under 3k rpm until the car is warm. No kick-down. No engine oil changes were made before break-in service. No sit-still idle for long time periord. Now break-in is done and slowly going maxing the RPM by 500 rpm per 500 km reached redline now. However, still avoiding long driving on freeway. |

I don't subscribe to the all the old methods, but to each his/her own. You'll either be laughing at me in 10 years, or we'll both have forgotten this conversation, and everyone will still be doing the same thing they used to. |

They already run them up to redline when they build it. I followed what they suggested in the manual, as they list it in the manual. Many vehicles do not mention anything.
