Advanced formula oils
Anyone hear of Royal Purple advanced, or high performance, motor oil? Evidently it goes beyond the synthetics, claiming that with proprietary additives "their oil has been proven in numerous independent tests to dramatically reduce engine wear, increase horsepower and torque, and reduce fuel consumption and emissions. Cars using their oils can also go further between oil changes, saving the owner time and money, and reducing the impact on the environment. More information about their products is available at the Web site www.royalpurple.com."

Its good stuff and many swear by it, I don't really think its necessary unless your tracking your car or driving it hard frequently or want to spend a little extra money on a little piece of mind.
Many people swear by it. I use it and am pleased, but really its just a synthetic oil to me. I dont know that it does everything you have listed but its very good quality.
