Excessive oil consumption (not due to leaks) is the use
of 1.9L (2 qts) or more of engine oil within 3,200 kilometers
(2,000 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 check
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. |
| • | 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 miss-fitted. |
