Just did another average for last 6 months (warm months here in Ontario) and 23.7 MPG is the number. This is a 2001 GT with the 3.8L non-turbocharged engine driven 70% City and 30% highway. I don't drive the car hard but not slowly either. Biggest change that I think improved the economy was the K&N (K&N 57 Series FIPK Air Intake) and the U-Bend delete but hard to tell as was doing bunch of mods to the intake and exhaust over that period. Planning a short highway jaunt and will try to get a highway mileage reading.
