I haven't specifically checked for the 6 cyl. models, but I think the dealer was overstating the need for premium. For everything but the Aero (including 6 cylinder models to the best of my knowledge) premium fuel is recommended but not required. Premium fuel will give better acceleration times, and somtimes better fuel economy (YMMV). Be careful with this, because depending on the gearing and model of the car, LOWER octaine fuel may give better fuel economy, but will always give poorer performance on knock sensor equipped cars like Saabs. And for Simon, when we talk about octane in North America we use the AKI numbers [Anti Knock Index = (RON + MON) / 2 ]. In Europe the octane is measured using RON (Research Octane Number) only. They do not use the Motor Octane Number. RON tends to be about 4 or 5 points higher than the AKI number.
