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.
Your vehicle’s engine is filled at the factory with a
Mobil 1
®
synthetic oil, which meets all requirements
for your vehicle.
Substitute Engine Oil: When adding oil to maintain
engine oil level, oil meeting GM Standard GM4718M
may 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.
Engine Oil Additives
Do not add anything to your oil. The recommended
oils with the starburst symbol that meet GM standards
are all you will need for good performance and
engine protection.
