DO NOT USE SAE
2OW-50
OR ANY
OTHER GRADE OIL
NOT RECOMMENDED
As shown in the chart, SAE low-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
5W-30. These numbers on an oil container show its
viscosity, or thickness. Do not use other viscosity oils,
such as SAE 20W-SO.
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 SW-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.
