Medium load is vital. Accelerating firmly, pulling in gear, and decelerating, up and down the gears..
Get those rings bedded in properly to ensure good compression and minimal blow by in the long term. Cruising is no good for that. Rings need firm combustion pressure to force them into the bore to bed in before they glaze up. I drive my m2c, on average, more gently now AFTER running in. During run in I only took it out on "run in" drives. At least 45 minutes for full heat cycle, open roads, wide use of revs (5k is plenty), up to 2/3 throttle, drive it enthusiastically. Load the engine, brisk runs to 100mph. Then get the oil changed (995 miles for me) and relax. Now i use it normally, odd school run, traffic jams, town etc. Last edited by doughboy; 02-20-2019 at 01:34 PM.. |

My suggestions to the OP are only to assist with the extended highway drive. I personally would not break in my engine this way. If highway driving is a must then varying and loading as much as possible is required.

Do you think people who are hard on the engine in the first 1200 miles keep the car for more than three years? My guess is no. |

The last two lease cars I had that I just pootled around in and didn't try to run in properly used quite a bit of oil. My "owned" 330i & 335i which I ran in robustly never drank a drop of oil performed faultlessly for years. |

The reason being, and this is just from being on these boards over the years, especially with the whole N63 stuff - what I noticed is that people who broke their engines in by babying them, seemed to burn a lot of oil with their V8 motors and thus, I think they probably got rid of them quicker. I noticed that those who broke their engines in more aggressively, did not burn oil and seemed to have fewer issues. Not even close to being scientific, just stuff I noticed. Like I said, lots of different theories and beliefs out there.

and... no issues with any of my new cars being picked up anywhere from 6 to 16 hours away from my house (since 2008 all of my cars were picked up out of state)... and... people pick their cars up in Germany and at the PCD here in South Carolina and put them on cruise control and drive all the way home or on the autobahn, and the fact is, these engines are amazing and while there are lots of things you can do to break them in properly (opinions vary here of course), the fact is, they rarely blow up from any of the multitude of ways used to break them in

This topic is always controversial and always on various car or motorcycle forums for a freaking long time.
There are multiple schools of thought on the best ways of breaking in a new motor...hard break in vs soft break in (manufacturer suggested). Just because OEM recommends a certain break in procedure it doesn't necessary mean it's the best way to go or the most sufficient. Unless there are key factual data points anyone can point to that suggest there are less long term engine issues with the OEM or soft break in vs hard break in approach, all opinions are just anecdotal. There's also a dependency on how long anyone keeps their cars and if engine issues crop up before or after one gets rid of a car. |

Regarding unlocking power at break-in service.
I read somewhere that they do reset the adaptations which makes sense to me. That would mean that although there is no difference in power the difference in power delivery would probably be quite big considering you have just spent 1000+ miles driving at half throttle and keeping it under 5.5k revs. |

The factory "engine testing" is not a break in. Additionally, these are not put under full load. The engine and ancillary parts do not "break in" as they do during street driving. Porsche's Andreas Preuninger addresses this topic very well in an interview. "Preliminary" or not, this does not serve a break in. I will always defer to the manual.

What's all that's done during the break in service for the M2C? The OG M2 service was only engine oil and differential. Is transmission fluid change included on the M2C as it is on M3/4?

In Spartanburg, every car is dynoed on a set of rollers, I forget what they are checking for but it only takes a minute or two. After that the car is taken outside, run on a test track, brought back inside and parked with other finish cars awaiting shipping. This was ~20 years ago but doubt they changed the process much.

+1 I too, do not "baby" the car and agree w/1-4. In fact, when babying the car early, I have seen higher oil consumption later in the car's life. |
