The ECU takes in the reading from fuel level sensor, but doesn't send it straight out to the display. Instead, it tweaks it a bit based on what you're current fuel consumption is, then that's the value that's displayed. You don't see this havig any impact, until you're low down the take - I've seen it from around 6 bars or less. Then if you have to tickle the throttle a bit for an incline, or lane change... it can put the gauge down a bit. And later up a bit. I've only noticed it on the motorway when the tank's that low - I reckon there's a much larger change in fule consumption for a bit of throttle on the motorway than the flat.

The fact that Fletch's capacity went up overnight whilst mine went down is incontrovertible proof of the existence of the Petrol Fairies, who move it about secretly at night.
A far more plausible explanation

I've noticed this with the Toyota Corrolla and the Audi....my guess is that all modern cars with an ECU 'do this'...just with the bar display on the S2000 it's more noticeable??

Why doesn't the guage just tell the real level and not try to be fancy and predict how much. I think we are more than capable of understanding the concept of the harder we drive the quicker we use up fuel. If we could see the real level then we would know exactly how much is left. Electronics for electronics sake, the world's gone mad.
