Germany, as far as i know are the only country that classifies the two syn. oils. Group III are labelled 'HC' or Hydrocraked' or Technosynthese, while PAO's/Group V's are labelled 'Full Syn.' or 100% Synthese. The rest of Europe....who knows? I wouldnt be surprised if they did replace PAO w/ Group III oils but, they still mix them w/ Esters/Group IV oils.
