An engine that has excessive oil consumption uses 1.9L (2 qts) of oil, or more, within 3200 km (2,000 mi). 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.
• Improper oil viscosity
  • Use the recommended SAE viscosity for prevailing temperatures.
  • Refer to Maintenance and Lubrication or the vehicle owner's manual for the proper oil viscosity specifications.
• Continuous high-speed driving
• Severe hauling, such as a trailer, causing decreased oil mileage
• Malfunctioning crankcase ventilation system
• External oil leaks
  • 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.
  • If the valve guides are worn, replace the cylinder head.
• Broken, improperly installed, worn or unseated piston rings.
• Piston improperly installed or improperly fitted.
• Plugged cylinder head gasket oil drain holes
