With an engine that has such close tolerances(any finely engineered powerplant), the oil must come up to a sufficient temperature so it is not too thick to lubricate properly. Kudos to BMW for using a better way to help you take care of your car. If you ignore their recommendations, the risk is higher engine wear and shorter engine life. If you live in temps near freezing, it can take 20 mins or more to warm up your engine to the optimal operating temperature needed to run it hard if left out overnight.

It just kills me when on cold mornings, Sub 20 or so, I see people pull out of neighborhoods, etc. and just FLOOR it when I know the car has been running less than a minute. That poor engine...........
