Hi,I checked my Engine Oil using the On-board computer and the level of engine oil was just slightly above the minimum mark. The on-board computer stated that the Engine Oil is OK.Is this really OK, considering that my car's mileage is now 5100KM and is due for servicing at 9000KM in December?Is the level of oil sufficient or should I top it up? If I should top it up, what Oil should I use? Or should I just contact Auto Bavaria Service Centre?Please advice.Thank You
