Hopefully not beating a dead horse or repeating something, but of the main US gasoline specifications is Dexos the "best". For clarity I do not have any GM vehicles.
Ford has the WSS-XXXXXX-XX specification and Mopar has the MS-XXXX, I purchased both of these standards and they essentially state that if the oil meets API-SP and ILSAC GF-6A it meets the requirements.
Dexos seems to take that to a higher level or at least shows how it improves over API and I get that a chart like this does not prove anything. Just curious about the Dexos specification requirements over the others. I am also wondering if using Dexos approved oils means you are (at least in theory) getting a higher level of protection.
Thanks for the thoughts...
