You guys are only looking at half the picture... the sender. The ECU can do whatever it wants with that signal, and it does. I have read that Americans have a weird thing about gas gauges in that they don't like seeing the gauge tick down immediately after refueling, and so most vehicle manufacturers fudge the gauge so that the first tick stays there longer than any of the others. On my CB (and my Mazda), the first tick is worth more than any of the others, and it gets progressively less as it goes down (my Mazda is especially bad, the first block is worth about 125miles, and the rest average 20).
The first bar for me is worth about .8 gallons and the flashing red bar is worth somewhere north of 1 gallon. The in-between ones, I have no idea, and don't care. You can get about 200 miles from a tank if you try. I have begun refueling at around 175 miles, and have somewhere between .3 and .5 gallon left when doing so. I usually get about 50 mpg.
