I have had mine down to 0 before, still had a few litres left when finally got to the servo.
I had a Vt Berlina about 5 years ago and did around 40 km with it showing 0 to go, it wasn't a very pleasant trip wondering if I will make it or not. My brother had a VX once that hit 0 that was it he ran out.
I think it varies between cars and obviously how you drive.
i'm filling the petrol when still got 1/4 petrol left in my tank.. just a habit.. lolz.. or see wether it's tuesday or not.. anyway, it's good having a petrol inside the tank otherwise air will come inside..
