well thats weird because mine chews through the first half a little bit faster i think, maybe because when you've got half a tank the cars a bit lighter?

in all honesty though i think a lot of people think they're losing fuel faster but it's just that sometimes they drive differently.

and yeah I've heard that fuel gauges mostly through the late 80's and the 90's are inaccurate as the needle only moves when the fuel level gets to certain points, although it moves very slowly...
