Well, here are my reasons for keeping track:

- I'm a geek.  I like numbers.
- If I see a decline in gas milage with no obvious explanation, I know
  that something's probably wrong -- the engine needs attention, a
  brake is dragging, etc.
- I can experiment and see how my driving style affects fuel economy.
  When gas gets expensive, this can become a way to save money.
- Knowing what kin do fuel economy I get helps with budgeting for
  trips and planning fuel stops.  What I get is almost never the same
  as the EPA number.
