I'll be able to tell you for sure in a week. I'm still at 3/4 tank and I do not want to extrapolate the numbers or trust the iDrive display just yet.
I do have to say though, the mpg on the display dropped quick as soon as the car began to adapt. Still though, I'm fairing good. It might also be attributed to the fresh oil and tranny fluid.
