Does anyone else agree when I say the 6 light fuel guage on the C3 is a strange thing to say the least? Firstly, although I always top up the tank until the pump clicks off, I rarely get more than 20 or so miles before the first light goes out. Does this suggest that I am unable to fill tank to the brim, or is it just the way the light works. The second thing is, even if I wait until the low fuel warning light and buzzer comes on whilst on the last light, when I go to fill up I can rarely get more than around 7 gallons in, even though it is a 10 gallon tank. Maybe this answers my first question, that I am not getting to fill the tank to full sufficiently. It appears the lights aren't literal representations of the state of the tank, i.e. each light does not represent 1/6 of the tank. Rather it uses the computer to work out the amount of miles that the car is currently achieving and displays the quantity of lights according to that. I'd be most interested to hear from others as to what their experiences are on the subject. Many thanks,
