Oil Consumption Diagnosis
WARNING: This page is about a different car, the 2011 Chevrolet Cruze. However, it is still accessible from the selected car via links, so may be relevant.
Excessive oil consumption, not due to leaks, is the use of 0.6 L (0.14 gallon) engine oil within 1000 kilometers (622 miles). The causes of excessive oil consumption include the following conditions:
- External oil leaks
Tighten bolts and/or replace gaskets and oil seals as necessary.
- Incorrect oil level or improper reading of oil level indicator
With the vehicle on a level surface, allow adequate drain down time and inspect for the correct oil level.
- Improper oil viscosity
Use recommended SAE viscosity for the prevailing temperatures.
- Continuous high speed driving and/or severe usage
- Crankcase ventilation system restrictions or malfunctioning components
- Valve guides and/or valve stem oil seals worn, or the seal omitted
Ream guides and install oversize service valves and/or new valve stem oil seals.
- Piston rings broken, improperly installed, worn, or not seated properly
Allow adequate time for rings to seat. Replace broken or worn rings, as necessary.
- Piston improperly installed or mis-fitted.
