I have felt zero difference between 87 octane and 93 octane, although at this particular time during winter my mileage is much worse than it was when it was warmer, at least in terms of driving around town. It doesn't feel more powerful or faster, but then again I'm not constantly running it against the redline all the time or into the higher rev ranges.

Although if you were to wind it out and then slam on the brakes it tends to hang revs for a second or two after you stop, which is not good.
