So according to stats the tank size for a 2007 Nissan Versa is 13.2. I’ve driven it till the gas light comes on. Fill up and the most I can get in the tank is 10.5 gallons. Is there really 2.5 gallons of gas still in the tank when the light comes on. According to stats that could be around 65 miles more of gas. Which I wouldn’t drive till it’s full empty but is it normal to not be able to use almost 3 gallons worth of gas tank space.
