You should be able to use any of the 3 octane ratings available in your area and the car will do fine with any of them.
There is virtually no difference in energy content among the octane grades of gasoline. The only meaningful difference is knock resistance. Because of this fact, the only difference you should experience will be the amount and duration of turbo boost that the engine management computer permits (it will govern this automatically). The higher the octane, the greater knock resistance, and therefore the greater tolerance for staying into the turbo boost longer.
The only time that you might notice effects of higher octane would be either (a) in hot, humid weather or (b) when you want to find a deserted country road and drive through the twisties fast. Other than that, you shouldn't be able to tell the difference. The effects on your engine should be zero.
