Me too. Didn't notice much difference but oh well.
Over on gassavers.org, theres a couple V6 aleros getting 36-37 mpg, and theres an ecotec cavalier in the top ten vehicles on the website, getting over 70mpg
Recently I got almost 35 out of my ecotec on a trip driving at a constant 50mph or so. If I go a constant 70-75mph, it drops down to about 30mpg.
Theres a mathmatical formula somewhere on gassavers.org that helps you determine exactly what rpms your engine burns fuel most efficiently based on the stroke of the engine. I had a hard time getting an exact result, but basically for the alero 4 and 6 cyl engines, they are most efficient when you do not exceed 2k rpms. Just something to keep in mind when monitoring your driving habits.
Also the A/C does consume alot of energy during city driving, keep it off whenever possible. It has less of an effect at constant speeds when you're not accelerating, since road horsepower required to maintain constant speed is relatively low.
