Drew, if you really get hooked on playing the mileage game, a Scangauge II is great for showing you how your gas pedal affects your mpg. On 800 mile trips to my mom's, my SE-R gets me 26 mpg at 72 mph, which is its EPA estimated highway mileage. If I slow down to 62 mph, my mpg figure rises to about 32 mpg. If I slow down even more to 55 mph, I can get 38-40 mpg. I can get 43 mpg with high speed pulse and glide.

I used to have to fill my tank midway down to my mom's. Now I always do the whole 400 miles on a single tank, regardless of which of my family's vehicles I drive.

A fuel consumption display (like the Scangauge) will show you that even with a 2 liter engine, you're getting well under 10 mpg when you're leadfooting it. If you accelerate briskly, you'll get about 15 mpg. If you accelerate slowly to moderately, you'll be getting about 20 mpg. What you aim for is best use of your engine's brake specific fuel consumption curve during acceleration, followed by gliding or cruising in the highest gear you can use.
