Using 91 or higher has shown to lessen the amount of timing pulled which should result in the engine running a bit more to its potential. Will you be able to tell the difference? Who knows, some say they think the car sounds smoother or feels more responsive, while some say that while they agree it may be better for the car, its too little to notice. I lean more towards that 2nd camp, and yes I try to run higher than regular graded fuel.
