The trip computer MPG tracker does not seem to be accurate. (High MPG was a key factor in deciding to get the Kicks, so that is my default screen when I'm driving.) I reset it every time I fill up. I drive mostly highway type miles. I'll be getting average MPG of 39 or more on the screen. Then, when I fill up, it turns out I got 36.5 - 37 MPG. I'm still happy overall, but disappointed that I didn't really get the nearly 40 MPG the trip computer told me I was getting. Also, it seems that the trip computer MPG reading goes up a bit when I'm driving a bit more aggressively, which doesn't make sense. Thoughts?
