Someone correct me here if you fee that I'm wrong. It seems to me that if you get good the advertised MPG's out the gate then you'll continue to get good to great gas mileage.

In contrast if your getting on the lower end of the MPG spectrum or should I say, crappy to partly good, then it may stay that way.

The issue comes when you take it back to the dealer and the tech says that the EB engines take 10K miles to break in. So now your stuck with a gas hog and no support on that issue alone.

To the OP, be patient if you can. Hopefully it gets better and WOW's you like mine has me.
