So you drove 3 people to the airport. 1 got dropped off with bags. The other 2 with bags chickened out at the last minute? ;-) [I suppose you could be running an airport car service] As for your MPG issue, I have also noticed significant increases in MPG at slightly slower speeds ('04 9-3). But is this really surprising? Fuel efficiency advocates have espoused for years that decreasing your speed by even just 5 mph makes a big difference in fuel economy. So a speed drop from 85 down to 65 is bound to have a sizeable effect on MPG. While I make no claim to know the mathematical aspects of vehicle aerodynamics and road resistance, the overall effect of the speed drop is obvious (as evidenced by your 9-5's trip computer). - tex
