Oil Consumption Test: Notes
The following diagnostic procedure is used to determine the source of excessive internal oil consumption:
NOTE:
- Oil use is normally greater during the first 16,100 km (10,000 miles) of service. As mileage increases, oil use generally decreases. Vehicles in normal service should get at least 1,450 km (900 miles) per liter (quart) after 16,100 km (10,000 miles) of service. High speed driving, towing, high ambient temperature and other factors may result in greater oil use.
- Define excessive oil consumption, such as the number of miles driven per liter (quart) of oil used. Also determine customer's driving habits, such as sustained high speed operation, towing, extended idle and other considerations.
- Verily that the engine has no external oil leak. See
