What Kind of Engine Oil to Use

Look for two things:

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.

You should 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.
