Scheduled Maintenance
7-6Engine Oil Scheduled Maintenance
Change engine oil and filter as indicated by the
GM Oil Life System (or every 12 months,
whichever occurs first). Reset the system. The system
will show you when to change the oil
-- usually between
3,000 miles (5 000 km) and 10,000 miles (16 000 km)
since your last oil change. Under severe conditions, the
indicator may come on before 3,000 miles (5 000 km).
Never drive your vehicle more than 10,000 miles
(16 000 km) or 12 months without an oil and
filter change.The system won't detect dust in the oil. So if you
drive in a dusty area, be sure to change your oil and
filter every 3,000 miles (5 000 km) or sooner if the
OIL CHANGE light appears. Remember to reset the
Oil Life System when the oil and filter have been
changed. See ªOil Life Systemº in the Index for
information on resetting.
