I disagree with that thought. The hosrepower rating and gas mileage #'s are based on 87 octane, there are no notations anywhere saying that the advertised power/torque and gas mileage figures are based on anything but 87 octane. There isnt even a note that 87 octane is Ok but 91 is preferred. To get the V6 into the highest timing table you have to run 93 octane all the time. For highest power/torque and gas mileage, run 93. The factory timing table's have to be very conservative as these little motors are running 11.5 to 1 compression and is tuned to run on 87. Spark knock city on a warm day with a manual trans on 87 octane, retard, retard, retard timing = a no balls V6
