I don't know how you or anyone else is calculating their mileage, but the proper way is to record your miles with the trip meter, then right down how many gallons it takes to fill the tank back up. So if you went 200 miles since your last fill up and it took 11 gallons to fill it up again. You got 18 mpg.

14-15 mpg in traffic and in town and 18-19 mpg highway at 75 mph with mods in my sig

I did notice a 1.2 mpg increase using 89 octane with the stock tune. I routinely get 26-28 highway to work at 55-60 mph. Although it has been 3 months since I had to fill it. Come on spring!!

15.8 it's a tossup, somedays i'll do more highway and some i'll do more city. i like to go fast.

I was driving into Seattle yesterday after filling up at a rest stop, and I glanced down at my dash to see that I was actually gettinig 30mpg since the fillup. (I reset the tripmeter during the fillup)

30MPG over 50 miles, including starting, mostly doing 65-85 mph. There must've been a tailwind or gradual downhill that I didn't notice.

More realistically I get about 26mpg on the highway, 21-22 combined for my mostly-highway driving.

(I'm stock with 3.31 gears)
