Owner`s manual

As shown in the chart, SAE IOW-30 is best for your
vehicle. However, you can use
SAE 5W-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
5W-30. 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
-20°F (-29”C), consider using either an SAE 5W-30
synthetic oil or an
SAE OW-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. Your dealer is ready to
advise
if you think something should be added.
