I reset the trip odometer and record all the gas, oil changes, any type of maintenance/changes and watch the mpg. Like Scott said, a drop will indicate something isn't right (unless it's winter gas). I know I'll never see great mpg with any vehicle with my daily commute. Normally 45 mph and less with multiple traffic lights all jammed into a 10 minute drive. So the vehicle barely gets up to temp. I've averaged 14 to 17.5 mpg in the winter between V8, V6 and 4 cyl vehicles so I can't complain about a V8 4WD truck getting 14 mpg when the 4 cyl 4WD truck only got 17.5 mpg. And now I need the V8 for towing the heavier boat/trailer so it's a moot point.
