Okay, this is not a thread on the general performance facts and myths of premium gas. Rather, since the Turbo does have different power outputs depending on the gas used, has anyone noticed a difference in MPG?
This might be hard to determine since many might drive more spirited on premium (zoom-zoom) and more conservatively on regular.
