Graph of MPG/fuel economy vs. speed, 2004 Aveo sedan (automatic)
Here's a graph of what MPG (U.S.) you could roughly expect to get at a steady speed (cruising) in similar conditions with a 2004 automatic.

Readings were taken with a ScanGauge calibrated to this car, repeated over the same test route, with the reading reset & read at the same points along the route.
Note the best fuel economy is in the highest gear with the torque converter locked at the lowest engine RPM. Speed kills... MPG! :) Once in top gear, it only goes down as MPH goes up. (This would be the same trend for manual transmission Aveos too, though the MPG figures would be a bit higher at a given speed.)
A/C was off for the test.
Test conditions:
Temp: 69F
Pressure: 30.29"
Avg Wind Speed: 2.53 mph
Road Length: 0.85 miles, slightly inclined
Raw data:
Speed(mph) South(mpgUS) North(mpgUS) Average(mpgUS)

At least I am not alone.....
Everyone blames me for my poor mileage. Because I only drive like 3 miles a day,'it doesnt get up to top engine temp.,it is all the stop and go,it is all the city driving,etc...' I still say it should give me low 30's with the way I drive, not like a nut. If I was driving like a 18yo zooming around, and carrying around tons of junk in my car, then maybe low 20's. It is old engne design and I accept it.
But to think I gave up a nice 'collectable' Ranger Edge for this car, to save money during the first 'oil crisis'....and I got better mileage in my turck with a big V-6, and it would now have maybe 30K miles on it. Well, this one stays with me, till it doesnt run or it gets crushed by someone. Its paid off, and still 99% reliable, cant do much better than that.
