After 13,764 miles I am averaging 26.7 MPG. (I used 515.6 Gallons of gas)
I keep a pretty meticulous mileage log.
Highest mileage observed was 33.1 on a long trip and the lowest was 18.9 which was mostly city driving.

Most of my driving is highway at about 65 MPH.
I primarily use SUNOCO 93 Octane gasoline and at the beginning of each month I throw in a bottle of Chevron Techron to insure the injectors stay clean.
And of course I have the 6 Speed coupe.
