Good day to everyone! I love the Power Flow graphic/ info on the touchscreen but am curious as to how accurate it is. I am still on my first tank of gas, so have not had the chance to refill and test the accuracy. When I had my Subaru Impreza 2015, the digital mpg readout was usually 2-3 mpg higher than my personal calculations. Thus, have any of you been able to compare what the touchscreen displays versus your calculation(s) at the pump?
