No problem, I knew where you were coming from - perhaps I wasn't clear enough in my clarification I just wanted to add that it was interesting that GM went out of their way to state that not all syn oils meet GM4718M because some customers may assume to use any oil marketed as a "synthetic".
(Copied directly from a 2004 CTS owners manual):
What Kind of Engine Oil to Use
Look for two things:
• GM4718M
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.
Refreshing to see that ConocoPhillips has integrity as well with their truthfull answer.
