As shown in the chart, SAE 10W-30 is best for your
vehicle. However,
you can use SAE SW-30 if it’s going
to be colder than
60°F (16°C) before your next oil
change. When it‘s very cold. you should use
SAE
SW-30. These numbers on an oil container show its
viscosity,
or thickness. Do not use other viscosity oils,
such
X SAE 2OW-SO.
NOTICE:
Use only engine oil with the American Petroleum
Institute Certified For Gasoline Engines
“Starburst” symbol. Failure to use the proper oil
can result in engine damage not covered by your
warranty.
GM Goodwrench@ oil (in Canada, GM Engine Oil)
meets all the requirements for your vehicle.
Engine Oil Additives
Don’t add anything to your oil. Your Aurora retailer is
ready
to advise if you think something should be added.
When to Change Engine Oil
See if any one of these is true for you:
0 Most trips are less than 5 to I0 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such as frequent
driving
in stop and go traffic).
Most trips are through dusty areas.
0 You frequently tow a trailer or use a carrier on top of
your vehicle.
If any one of-. these is true for your vehicle, then you
need to change your oil and filter every 3,000 miles
(5 000 km) or 3 months -- whichever comes first. (See
“Change Oil Message”
in the Index.) If the CHANGE
OIL NOW message appears in the Driver Information
Center,
you should change your oil.
If none of them is true, change the oil and filter every
7,500 miles
( 12 SO0 km) or 12 months -- whichever
colnes first. (See “Change Oil Message’‘
in the Index.)
Always reset the engine oil life to 100% after every oil
change.
