Just drive the car as it's meant to be driven, no worries!  |
For the past decade (since the advent of OEM synthetic oil), BMW's "condition based service" dash readouts have called for oil changes averaging 15,000 miles, with the low at about 12k and the high about 18k. So I'm curious where you get 12k as the "BMW recommendation".
