Anyone who understands the principles behind an octane rating will tell you that there's absolutely no need to increase a fuel's octane rating if the car's not designed to take advantage of it. The spark timing is set for premium fuel, raising the knock rating further cannot change spark advance any further.

Now adding a fuel with higher heating value can be a benefit, but with greater power adds greater wear and reduced longevity, not to mention compatibility issues between the fuel and fuel system components. In addition, there's fuel metering values and after treatment equiptment to worry about. I'd just stick with the stuff from the pump.
