  1. Yesterday a warning for P1455 came up. When I got home I looked it up and saw it was for the fuel evap system and figured I’d look into it further when I had time in a few days. Today the car drank 1/2 tank of fuel driving approx 130 miles, but the on screen MPG didn’t change. Any idea where it might be dumping the fuel?
