Owner's Manual

What Kind of Oil to Use
Look for two things:
GM4718M
The Corvette engine requires a special oil meeting
GM Standard GM47 18M. 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 GM47
1 8M.
NOTICE:
If you use oils that don’t have the GM4718M
Standard designation, you can cause engine
damage not covered by your warranty.
