Your fuel log entries show a nice jump at the end of Oct to the beginning of Nov. Is that the comparison you're making? (Trying to get a sense of what you consider a "decent" improvement.)

If that's the case, you may already know that this is the time of year northerners' fuel economy would normally tank anyway due to cold weather. For the average driver, cold has a significant impact.

So your improvement may be real, but masked by the temperature hit. You could check against last year's fill-ups at the same time of year (if it's the same kind of driving you're doing).

If the car doesn't have a fuel consumption display, I'd also highly recommend getting instrumentation in there - either a ScanGauge or a MPGuino. Can't underestimate the importance of feedback for adjusting driving habits.
