I know there have been posts already on this subject, but I would like to raise the issue again, as I am concerned about the amount of oil my M5 has burned since new. I am about to reach my first service of 1200 miles (2000km) and up until now the car has used 1.3 liters. I have rigidly stuck to the running in regime. Is this what others have experienced? is it normal? or should i be concerned?
