in this manual. Also, the oil change reminder will not
detect dusty conditions or engine malfunctions that may
affect the oil. If you drive in dusty areas, change your
oil after every 3,000 miles (5 000 km) or three months,
whichever occurs first, unless the DIC instructs you to
do so sooner. Also, the oil change reminder does not

As in the chart shown previously, SAE 5W-30 is best for
your vehicle. However, you can use SAE 10W
-30 if it's
going to be 0F (
-18C) or above. These numbers on
an oil container show its viscosity, or thickness. Do not
use other viscosity oils, such as SAE 20W
-50.
NOTICE:
Use only engine oil with the American
Petroleum Institute Certified For Gasoline
Engines starburst symbol. Failure to use the
recommended oil can result in engine damage
not covered by your warranty.
GM Goodwrench
oil meets all the requirements for
your vehicle.
If you are in an area where the temperature falls below
-20F (-29C), consider using either an SAE 5W-30
synthetic oil or an SAE 0W
-30 oil. Both will provide
easier cold starting and better protection for your engine
at extremely low temperatures.
Engine Oil Additives
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 12,000 miles (20 000 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 12,000 miles
(20 000 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 CHANGE ENG OIL light
whenever the oil is changed.

How to Reset the CHANGE ENG OIL Light
To reset the CHANGE ENG OIL light,
do the following:
1. Turn the ignition key to RUN with the engine off.
2. Fully press and release the accelerator pedal
three times within five seconds.
If the CHANGE ENG OIL light flashes for
five seconds, the system is reset. If the light
does not flash, repeat the procedure.What to Do with Used Oil
Did you know that used engine oil contains certain
elements that may be unhealthy for your skin and could
even cause cancer? Don't let used oil stay on your skin
for very long. Clean your skin and nails with soap and
water, or a good hand cleaner. Wash or properly throw
away clothing or rags containing used engine oil.
See the manufacturer's warnings about the use and
disposal of oil products.
Used oil can be a real threat to the environment. If you
change your own oil, be sure to drain all free
-flowing
oil from the filter before disposal. Don't ever dispose of
oil by putting it in the trash, pouring it on the ground,
into sewers, or into streams or bodies of water. Instead,
recycle it by taking it to a place that collects used oil.
If you have a problem properly disposing of your used
oil, ask your dealer, a service station or a local recycling
center for help.
