I've been averaging between 18-19 mpg, last I checked.
The only changes I've made recently, as in since I last filled up, are the tires and the GTA mufflers. I don't expect the figures to change any.
I dont live by the mileage computer, but it used to show about 17.5 mpg on my same route i drive to work, now it reads about 20.4 mpg, so i would assume it did and i have been driving easy to make sure its not a fluke.
