What Kind of Engine Oil to Use
Look for three things:
• GM4718M
Your vehicle’s engine requires a special oil meeting
GM Standard GM4718M. Oils meeting this
standard may be identified as synthetic. However,
not all synthetic oils will meet this GM standard.
Look for and use only an oil that meets GM
Standard GM4718M.
Notice: If you use oils that do not have the
GM4718M Standard designation, you can cause
engine damage not covered by your warranty.
• SAE 5W-30
As shown in the viscosity chart, SAE 5W-30 is best
for your vehicle.
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
have the starburst
symbol on the container.
This symbol indicates
that the oil has been
certified by the
American Petroleum
Institute (API).
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.
