As a general rule, most cars have about 2.5 gallons left in the tank when the gas light comes on.
So depending on how many miles you get per gallon, you can probably go anywhere between 30-60 miles.
How much gas do you have when the light comes on?
A: The amount remaining in the tank varies with make and model, and sometimes substantially from car-to car, depending on the tolerances on the mounting of the fuel sender in the tank. Short answer: Between one and two gallons. Long answer: Run the car until the light comes on.
How long can you drive with the gas light on?
So, if your car or SUV gets 20 mpg, assume that you can drive about 50 miles after your gas light goes on until the sickening realization that you are totally out of gas. Also consider that stop-and-go traffic can reduce your fuel efficiency and drop that number significantly.
