SAE 5W-30
As shown in the viscosity chart, SAE 5W-30 is best
for your vehicle. However, you can use SAE
10W-30 if it is going to be 0°F (-18°C) or above.
These numbers on an oil container show its
viscosity, or thickness. Do not use other viscosity
oils such as SAE 20W-50.
Oils meeting these
requirements should also
have the starburst
symbol on the container.
This symbol indicates
that the oil has been
certified by the American
Petroleum Institute (API).
You should look for this on the oil container, and use
only those oils that are identified as meeting GM
Standard GM4718M and have the starburst symbol on
the front of the oil container.
