Impala V6-3.8L VIN K (2004)
Oil Change Reminder Lamp: Description and Operation
WHEN TO CHANGE ENGINE OIL
Your vehicle has a computer system that lets you know when to change the engine oil and filter. This is based on engine revolutions and engine
temperature and on a maximum mileage of 10,000 miles (16 000 km). Under severe conditions the indicator may come on before 10,000 miles (16
000 km). Never drive your vehicle more then 10,000 miles (16 000 km) or 12 months without an oil and filter change. Based on driving conditions,
the mileage at which an oil change will be indicated can vary considerably. For the oil life system to work properly, you must reset the system every
time the oil is changed.
When the system has calculated that oil life has been diminished, it will indicate that an oil change is necessary. A "CHANGE ENGINE OIL" message
or a "CHANGE OIL" indicator will come on. Change your oil as soon as possible within the next two times you stop for fuel. It is possible that, if you
are driving under the best conditions, the oil life system may not indicate that an oil change is necessary for over a year. However, your engine oil and
filter must be changed at least once a year and at this time the system must be reset. It is also important to check your oil regularly and keep it at the
proper level.
The engine oil life monitor will not detect dust in the oil. If the vehicle is driven in a dusty area, be sure to change the oil every 5,000 km (3,000 miles)
or sooner if the "CHANGE ENGINE OIL" light is displayed.
If the system is ever reset accidentally, you must change your oil at 10,000 miles (16 000 km) since your last oil change. Remember to reset the oil life
system whenever the oil is changed.
