I definitely DON'T recommend anything but premium fuel. We tried two tanks of mid-grade (89 Octane) in our '99 Q45, and experienced several problems soon after (knock sensor, IACV, EVAP valve, air flow sensor). Coincidence? Maybe...maybe not. The emissions system has to try to compensate for the lower octane, which could "stress" the various components.
