I also noticed that I get max mpg when using 93 octane. I actualy got 2 mpg less when running mid-grade.

The trick to good gas mileage on any car is filling up when the car is at 1/2 a tank. Fuel injectors don't work as hard and sediment from additives don't cause faster burning of fuel from 1/2 to empty. If you don't believe me, try it! Notice how from F to 1/2 you usually get 200 or so miles and then only 85 more from 1/2 to E? Try filling up every 1/2 tank and see. =)
