Causes |
| The causes of excessive oil consumption may include the following conditions: |
| Preliminary |
- External oil leaks.
- Incorrect oil level or improper reading of the oil level indicator.
With the vehicle on a level surface, run the engine for a few minutes, allow adequate drain down time (2-3 minutes) and check for the correct engine oil level.
- Improper oil viscosity.
Refer to the vehicle owners manual and use the recommended SAE grade and viscosity for the prevailing temperatures.
- Continuous high speed driving and/or severe usage.
- Crankcase ventilation system restrictions or malfunctioning components.
- Worn valve guides and/or valve stems.
- Worn, missing or improperly installed valve stem oil seals.
- Piston rings broken, worn, not seated properly.
Allow adequate time for the rings to seat.
Replace worn piston rings as necessary.
- Piston and rings improperly installed or miss-fitted to the cylinder bore.
