All that is needed is for those companies which are still using PAO to educate the public. To boldly proclaim their PAO content and let people know if it doesn't say PAO, likely it is Group III. Why wouldn't the company using the better base oil, proclaim that fact? Only reason I can think of is they may not do it in case pricing gets to where they too want back down to Group III. If I want any PAO I will go to Amsoil because, as stated above, they do tell you which of their oils are PAO.
