Read your new BMW OM and follow the break-in procedure and you'll be just fine. BMW backs your vehicle with a 50K mileage warranty if you use their prescribed break-in procedure because they have the most expertise on your engine, not some website jerk or well meaning forum participant who has no objective engine break-in test data to support their beliefs.
BMW puts their money where their mouth is. Engine break-in is quite simple. Drive the car normally for the first 600-1000 miles without excessive engine RPM (stay below 4500 RPM) or loads, (don't lug the engine or use WOT). Do not use WOT for the first 600 miles. Vary engine speed and throttle position frequently. Do not baby the engine, just drive it like a "normal" mature, respectful adult would drive.  |
I suppose you will change your oil every 15k and the transmission is good forever?
