An engine that has excessive oil consumption uses 1.9L
(2 qts) of oil or more within 2,000 miles (3200 km).
The following conditions are indications 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 General Information 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 |
| - | Replace the valve stem seals. |
