Don't add anything to your oil. The recommended oils
with the starburst symbol are all you will need for good
performance and engine protection.
When to Change Engine Oil
Your vehicle has a computer that lets you know when to
change your engine oil. This is not based on mileage,
but on engine revolutions and engine operating
temperature. When the computer has calculated that the
oil needs changing, the GM Oil Life System will
indicate that a change is necessary. The mileage between
oil and filter changes will vary depending on how you
drive your vehicle
-- usually between 3,000 miles
(5 000 km) and 7,500 miles (12 500 km) since your
last oil and filter change. Under severe conditions, the
system may come on before 3,000 miles (5 000 km).
Never drive your vehicle more than 7,500 miles
(12 500 km) or 12 months (whichever occurs first)
without an oil 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. Remember to
reset the Oil Life Indicator whenever the oil is changed.How to Reset the Oil Life Indicator
After changing the engine oil, the system must be
reset. To reset the indicator, use one of the
following procedures:

to verify the new setting and DONE will be
displayed for one second.
7. Once the indicator has been reset, scroll until EXIT
appears on the display.
8. Press the DISP button to exit programming. A chime
will be heard to verify the exit.
