Compliant means that Schaeffer's Manufacturing states that their engine oil is compliant with the specifications GM has established for their engines.
And then there is
licensed, which is the operative word when it comes to dexos. The oils on
this page are the ones that are licensed, the ones not on that list are not.
Once again you attempt to obfuscate when you would be better off with a clear explanation, and let people decide if the manufacturer's reputation is good enough or not. I tend to believe it is, but you aren't helping by your constant weasel words.
