Fellow members, How often do we normally change transmission oil for M54 engine model? BMW suggests that the oil can last forever. You don't even have to take a peek. Some mechanics suggest that BMW Long Life is just a name or a gimmick. I can be used for a long time but cannot be used forever. You still need to change the oil. Which one is true? Now, how many people out there with M54 engine has never change their transmission oil?
