I have 4500 miles on my X1I am getting 27+ MPG driving approx 70% freeway (but in traffic) I use the eco mode almost all the time. BTW, I had my dealer change the Auto stop start to last use mode. They can do that, it is a software change. I just get in and start it and the feature is automatically disabled. Which is the way they should have set it up to begin with.
My average speed is 40 MPH.
