Page: 276 / 436

For Vehicles with the 2.0L L4 Engine Only
Look for three things:
•
GM4718M
This vehicle’s engine requires a special oil meeting
GM Standard GM4718M, such as Mobil 1
®
or
equivalent. 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
synthetic oil meeting all requirements for this vehicle.
