What Kind of Engine Oil to Use
Look for three things:
GM4718M
This 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.
Use only an oil that meets GM Standard GM4718M.
Notice: Using oils that do not have the GM4718M
Standard designation can cause engine damage not
covered by the vehicle warranty.
SAE 5W-30
SAE 5W-30 is best for the vehicle. These numbers
on an oil container show its viscosity, or thickness.
Do not use other viscosity oils such as SAE 20W-50.
American Petroleum Institute (API) starburst
symbol
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).
This vehicle’s engine was filled at the factory with a
Mobil 1
®
synthetic oil meeting all requirements for this
vehicle.
Substitute Engine Oil: When adding oil to maintain engine
oil level, oil meeting GM Standard GM4718M might not
be available. You can add substitute oil designated
SAE 5W-30 with the starburst symbol at all temperatures.
Substitute oil not meeting GM Standard GM4718M
should not be used for an oil change.
