Yep.
"Dexos" is no more nor less than a cash grab on the part of GM.
Most of GM's North American output would run happily on any SL/SM/SN oil.
For those few applications requiring a better oil, GM could have simply required an oil meeting the current, recoginzed, A3 standard, rather than coming up with some pay to play standard of their own.
GM ain't Porsche, Mercedes or BMW.
