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.
