The reason I'm asking is that I noticed that on some Syn oils they are using a GM code '6094'(?) and showing 'performance'. I was wondering if GM is dropping the 4718M code to a newer code for their newer Vettes. Or is 4718M still good for newer Vettes? I also have a Solstice, which requires 6094, but not necessarily a synthetic requirement. Maybe someone here has a newer Vette that may help or one of you tech guys. thanks,
