Oil Consumption Diagnosis
An engine that has excessive oil consumption uses 0.9 L (1 qt) of oil, or more, within 3 200 km (2,000 mi). The following list indicates the conditions and corrections of excessive oil consumption:
* An improperly read oil level indicator dipstick
- Inspect the oil level while the vehicle is parked on a level surface.
- Allow adequate drain-down time.
* Improper oil viscosity
Use the recommended SAE viscosity for prevailing temperatures.
* Continuous high-speed driving
* Severe hauling, such as a trailer. This causes decreased oil mileage.
* A malfunctioning crankcase ventilation system
* External oil leaks
- Tighten the bolts, as needed.
- Replace the gaskets and seals, as needed.
* Worn or omitted valve guides and/or valve stem seals
- Ream the guides.
- Install oversized service valves and/or new valve stem seals.
* Broken or worn piston rings
* Improperly installed or unseated piston rings
* Improperly installed or improperly fitted piston
* Plugged cylinder head gasket oil drain holes
* Damaged intake gaskets
