OMG!!! Fuel mileage alMost doubled!
 
Ours just turned 10,000 miles and at just over 10mpg we were not impressed with the mpg. Almost to the mile after hitting 10k our M started saying 18-20 mpg on the dash so I checked it on the last tank and the calculator gave it 17.4!

Hum..... I wonder if it's a break in procedure? Did you look in your owners manual?

10ish' mpg = sports, M mode. 17mpg = grandpa mode.

how do you drive it? I had 22k miles on my 2010 M and it never changed...

I thought my mpg changed but then I realised I was reading the average speed number :rofl:

Reads like "new math" or, funny arithmetic...but, glad the OP got off the 10 mpg. :yikes:
Hard to understand "10 mpg", and doubt it "improved" that much overnight.

I've been driving our '02 Vette, as a daily driver, for the past several weeks: lots of trips up and down our 4 mile mtn road, errands in town, etc.,
and a few ballz out rip runs up on the BlueRidgePkway; last tank gave 19.2 mpg.

Must be the avoirdupois of the X/M?

F Cars do better than "10".
