BMW Engine Oil Service: Notes

All models (except M Roadster/M Coupe up to 2001) feature extended Oil Service intervals of 15,000 miles. This is a result of improvements in oil quality and durability provided by synthetic oils. Oil changes based on time have also been extended from 1 year to a maximum of 2 years unless indicated otherwise by the Service Indicator System.
