But why use it if it barely makes a difference to MPG?

I drive in Los Angeles, a lot of freeway traffic - sometimes flowing, sometimes not. Using EcoPro my fill up calculations were usually around 27.5 (sDrive 28). I'll have my first big fill-up this weekend since the X1 was serviced for low coolant and the trip computer was reset. Right now the trip computer actually shows an even 28 for the 200 or so miles on the current tank of gas. If that holds up - goodbye, EcoPro. And we'll see if the coolant problem ever resurfaces.
Really? After about 4000 miles, I got around to trying Eco Pro with my temp gauge, and discovered it immediately runs up temp from about 215 deg f to 225 deg f.

So I guess we both found out Eco Pro mpg has a cost.

BMW's already have high heat efficiency factored in.
