I'm pretty sure the light just comes on when you have a gallon left, so however many miles your Taurus gets to the gallon will determine what you have left. I've never run out, but the gas light has been on a time or two and I've driven up to about 20 miles and have been fine.
No sense pushing it if you don't have to and such, but I think you can count on there being about a gallon of gas left.
i toatlly agree. i just watch a report onthe news about "how far can your car go after the gas light comes on?". The news man reported tha ford cars are equiped with this mechanisim for safty assurance. Ford is primarily the only one that does this but it never quite said how many gallons /miles you have left after the gas light comes on ....or maybe i went to the restroom on that descusion how ever i love my ford car!!!!
So you were pinching a loaf when you should have been paying attention. what is your problem?
