To determine if an overfilled crankcase is causing excessive oil consumption, perform the following:
- Ensure the vehicle is parked on level ground.
- Drain the oil pan. Refill oil pan to the proper capacity, refer to MBE 900 Service Manual
(6SE9007), preventive maintenance.
- If a calibration check indicates that the oil level is off by more than 2.0 mm (0.079 in.), contact Detroit Diesel Customer Support Center at 313-592-5800.
- Check for oil leaks; refer to "7.2 External Oil Leaks"
