for you, i would see what has changed in the past year. And then recheck everything it could be, like tire pressure, fluids are too dirty, etc.

actually that would work for everyone too.

my mileage has dropped dramatically, but for me it was idling a ton. i don't really care because it will go back up when i drive, and i generally only fill up twice a month.
