I just drove the car home this morning. About 250 miles at about 65-70. Not exactly flat but I pulled 31 mpg. This car has 135,000 miles and I have no idea what tire pressure was, how old the plugs are, etc. I think on a flat surface after a tune and what not I could do 33-34 MPG.
I was at about 1600 RPM at 65 MPH.

Alex- What MPG do you get with no wind, on a flat road, at 65 MPH? Best way to be accurate is to drive in 1 direction, then turn around driving the same exact route back, and measure overall fuel consumption and distance traveled.
