An NG turbo is supposed to run on premium. If you use lower grade, it may knock under acceleration. When that happens, the engine will retard the timing to stop the knock so you get worse performance. You will compensate by opening the throttle more and using more gas as a result. Most folks report MPG to be a couple MPG better using premium, offsetting the extra cost, with the added performance bonus. YMMV, Bob
