For 1990-2009 cars

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
