An oil change on a rear-engine Porsche is about $300 because it's a total PITA. BMW corporate is paying for the oil change on their cars so they're going to try and stretch it as much as possible. Modern engines are built with such tight clearances that the break-in period in reality is pretty short, but I still like to avoid synthetics in that time.
