tonylauno1 7 Report post Posted October 2, 2009 Doesn't necessarily mean your engine is much cleaner. Could be that the oil isn't doing its job as well? Wouldn't have a clue, I guess it's because the engine is still dirty. Might use the same oil as my previous car to see but I just keep flushing each oil change.

tonylauno1 7 Report post Posted October 2, 2009 E46 service lights set to 25k and adjust the interval by semi logic dependant on drivers driving style I thought that was the case, with my style of driving every 900km the service interval would decrease by 1000km. .
