everytime i fill up when i am on e with the gas light on my car doesnt take more then 12 gallons to fill it up. i get maybe if i am lucky 200 mile a tank and its almost all highway driving. does anybody else have this problem, and how many gallons of gas should it take i dont think its should only be 12 gallons.

 

I know the 1.8t has a 15ish gallon tank.
