Why does the petrol meter change in my Ford Ka?

When i am driving I could have quarter tank left, then suddenly it's way under, then when I park it goes back up.
Really Marc? Oh no, i thought i was a good driver!
 
You must drive "erratically", speed up too fast, and brake too late; the gauge is simply driven by a float on top of the gasoline, if it is 'moving about', that means the petrol in your tank is moving about a lot...

(Another possibility is that your tank isn't venting properly....does the gas-cap make a "sucking noise" when you undo it to put more petrol in?)
