Locally (not city but rural), I get a consistant 22 - 22.5 mpg calculated. I state this as consistant as it is averaged over 7 months. I have the 3:21 ratio, 6 spd. I attempt to shift at or below 2000 rpm and drive in the 1400 to 1500 rpm range. This obviously will stray a bit due to road conditions but she has remained reasonably stable. I took her on a 600 mile highway trip and she gave me 25 mpg calculated. My average speed on I80 and I81 was 60 mph and the selection of either 5th or 6th gear was strictly by "seat-of-the-pants" driving. The built in mpg readout is off by 1.5 mpg and has also read off by this amount consistantly. Very slow deliberate starts and stops have also helped with this. Take care... Mike
