106 How Many Miles Can You Drive After Burning a Gas Light?

My father's vehicle, wv, they are going another 60 70 km after the petrol lamp is lit. For 106 this situation
How many km can you travel?

I do not guess that ours will go that far, I made 35 40 km, the speed is constant at 90km .. I was coming across.

I go as soon as the lamp lights up, I'm afraid of the gas, I'm spending more money on the road than staying on the road.

For GTI 40.50 xr quick you will travel 75 to 80 km, but these values are over 90 at idle.
