First tank of gas = 11.17 mpg.

[crabman]

The car claimed 12.9 but the math at the pump says, uhuh, 11.17. lol Cant hardly wait to see what I get after the break in period ends and I can stop babying it.

highway man, like 380-400 lol

[mrkbbd]

that's not bad for break-in at all as others have said. I was in the 8 range for the first few tanks. The service indicator is based more on gallons used than miles driven, so mine indicated it wanted the break-in service around 700 miles.

There's something wrong if you are getting 13mpg on the highway unless you are taking the highway to heaven.

Do you ever go above 3K rpm?

[4corners]

I'll trade any of you my 328xi that gets 24.7 mpg for your M3.

Wow, you must know the secret password to the increased fuel economy mode in idrive! A little better than half my cars mileage for the tank was on the freeway coming home from Seattle and the rest in town. I drove with light to at most moderate throttle, nearly all in sequential with shifts occurring anywhere from low rpm up to 4k or so. Kind of as you would drive a stick when in traffic and with no hurry. I didn't use cruise on the freeway as I like to vary the speed quite a bit in the early miles so I probably lost a little there but it wouldn't have been much. I'm pretty sure my numbers have nowhere to go but down too.
