Other implications such as locking them down to a specific formulation and basestock supplier are very big considerations. Thus, everytime Amsoil would want to switch basestock suppliers or tweak their formula, they would have to be re-certified. Not cost effective at all, and does not allow for incremental product improvements.
Excuse my ignorance, but how would you know if the new oil is still certified after the formula is changed without being re-certified by an independent organization? Could any change to the formula potentially fail the certification?
 
I am giving consideration to using Amsoil SSO 0W30 after the vehicle reaches 100,000 miles. Until then, I will use oil that is certified to GM6094. This will be, at least, a couple of years from now.
