Most of us have noticed better mileage with premium so it doesn't hurt to pay a little more. The 9-3 and 9-5 will detune the engine with lesser grades so it won't hurt but won't help either. I guess it's really up to preference.
My wife's 9-5 Aero gets premium and my 9-3 gets premium<->middle grade back and forth. No real reason why I do that. Just based on my mood really.
