According to Ford, the 2007 Ford Focus has a fuel tank capacity of 13.5 gallons. The fuel light typically comes on when there is approximately 2 gallons of fuel remaining in the tank. This means that you can expect to be able to travel approximately 54 miles (at an average fuel economy of 27 MPG) after the fuel light comes on in a 2007 Ford Focus.
NOTE: It is not recommended to drive a vehicle continuously when the fuel light is on, as this could damage the fuel pump.
