Others who got the low coolant level alert - were you using EcoPro often? I was.

I have stopped using EcoPro and am watching my mileage, which at the moment seems to be holding up real well. If I don't start to notice a significant drop in MPG, I'll lay off the EcoPro, even though it's not substantiated that the low coolant level phenomenon is related to sue of EcoPro. 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.
