the commodore digital distance to empty feature....is not that great. My boss drives a late model hsv. its hardly accurate....plus it goes up and down based on how ur driving at that time, like when u go up a hill, it recalcutes the figure. its just a safe guestimate on how many kms u got left....new bmws have the same feature. but both cars, i have seen been driven with guage saying 0kms left, and still getting 30-40kms out of it. We use shell cards in our company, so the directors wont fill up else where, so they go til they find the first shell servo.

the polo i am driving fuel light goes off at about quater tank. But i have driven it for about 20kms....past the guage sitting on empty. i filled the tank and it filled up to like 43 or 44 litres (its a 45litre tank)....i think they do it so that its a safe measure so u dont run out of fuel.
