... was my calculated[1] fuel consumption rate for an ~84 mile drive from Fredericksburg, Virginia, to Reston, Virginia on Sunday. I intentionally drove as conciously of fuel consumption as possible, without causing a dangerous situation. Average speeds were in the
55-63 mph range, with just a few stoplights and runs through the gears. Mostly 4-lane state and county highways, with speed limits of either 55mph or 60mph, but with most traffic running at 65-75 mph; I stayed in the right lane and lost count of the number of vehicles that passed me. I passed *maybe* 10-12 trucks during the entire run.1997 Miata 1.8l "M" edition, dead stock, 60k miles on it, with top down, and two passengers; normal (mostly around town) MPG is ~28; normal highway mpg is ~30-32.
I was pleased with the results, but it was difficult to drive the Miata that way, even for just 84 miles! I probably won't do it again, just to save a couple of tenths of a gallon of gas. ;-)
