Still on my first tank of gas. Just got the car last friday. My MPG so far is just shy of 18 with probably 80-90% city driving. I was hoping for closer to 20 as mine is FWD with estimate at 18-26. We shall see if it improves. Also, it was suggested to try mid grade gas. I guess the manual mentions using mid grade for best performance. Not sure if anyone has noticed an improvement but I may try that on my next tank.
