Because of the shape of the tank and the way the gauge works (a float on a resistor that turns through an arc measuring a vertical drop) so the gauge spends alot of time in the middle
Also 50liters is unlikely to of filled it up even if it read full. The tanks are officially 60L but they take nearer 70L
Most people here who are keen on measuring their fuel economy regularly go to the same fuel station and fill up to a certain point (first click, 3rd click or brimmed are the normal) then reset their trip computer. That way the next time you fill up the tank to the same point you know your mileage and exactly how much fuel has gone into the car every time. For me it used to be about 530 miles to a tank.
