An engine that has excessive oil consumption uses 0.9L
(1 qt) of oil, or more, within 2,000 miles (3 200 km).
The following are conditions and corrections of excessive oil consumption:
| • | Improperly read oil level indicator (dipstick) |
| - | Check the oil while the car is standing on a level surface. |
| - | Allow adequate drain-down time. |
| - | Use the recommended SAE viscosity for prevailing temperatures. |
| - | Refer to Maintenance and Lubrication for the proper oil viscosity
specifications. |
| • | Continuous high-speed driving |
| • | Severe hauling, such as a trailer, causing decreased oil mileage |
| • | Malfunctioning crankcase ventilation system |
| - | Tighten the bolts, as necessary. |
| - | Replace the gaskets and seals, as necessary. |
| • | Worn or omitted valve guides and/or valve stem seals |
| - | Install oversized service valves and/or new valve stem seals. |
| • | Broken, improperly installed, worn, or unseated piston rings |
| • | Improperly installed or improperly fitted piston |
| • | Plugged cylinder head gasket oil drain holes |
