The higher octane doesn't burn colder... it requires more heat to ignite than 88. That's why some cars knock using the lower grades, the fuel is igniting before the spark is fired. Also a higher octane burns more completely than the lower grades.
All in all, you're getting more power for the cost. And with that slight increase in performance, it requires less fuel to get up to speed, there for keeping you from having to increase the throttle.
But at a certain point, the cost can outway the benifits. I say get your avg. MPG doing NORMAL driving with the 93, then try it once with the 95 and see.
I can tell you from when I made a trip with my Maxima, I noticed a HUGE difference between the 91 here, and the 97 back home.
