As the line that seperates GrpIII and Full PAO blurs, and the performance aspects of each as well blurs, there is only one question left to answer? Which of the most commonly availble PCMO is the most "Slippery". I know that with Mobil 1, the oil that I am currently using for both of my vehicles, is very slick to the touch. And if the only really last defining line is reducing wear in all aspects, then the most "Slippery" oil, or the oil with the most Friction Modifiers, should be the "Best"
