Break-in is a highly debated topic, random internet people (including myself) act like they have all the answers, but don’t.

My brother is a BMW tech - he said to drive it like you stole it from day one. He says cars being babied out of the gate ultimately never heat cycle enough to fully seat rings and that’s the reason many BMWs consume oil from day one. Don’t sit at a constant RPM for a long time. Allow car to cool between aggressive runs before doing another.

There are arguments on both sides that make sense.
