If you do not have any knock or ping you will gain nothing by using the premium. Newer cars have knock sensors and they will retard the timing and lower the power, otherwise use the lowest grade that does not produce ping. If you are not getting any ping, then you will not get any more power from the higher octane. The car will be faster because there will be less money in your pocket therefor lighter, but I do not think that will make much difference in a big car like this.
