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."
Hype or something to it?
