New N63 Engine - Worse gas mileage?

Hi All,

I recently went through the engine replacement nightmare, fortunately during the last couple of months on my CPO. My replacement did not was not really related to the BANG settlement. First I had my valve seals replaced, then on my way home from that repair, "something" failed and I had metal shavings clogging my vanos sensors. BMW had been providing me a rental car for 4 months prior to getting a new engine. Finally, about 4 weeks ago, they let me know that a new engine came in and they were going to install it. I've had the 2013 X5 5.0 for about 2 weeks now and everything seems to be performing just fine with one exception. I've noticed that my MPG is lower by 1-2 MPG. Prior to the engine replacement i was getting about 14-15 MPGs. Now, I am getting 12-13 MPGs. My driving has remained consistent. as with the old engine. If anything, my driving right now is more conservative as I feel like I need to break in the engine. So spirited driving has been virtually non-existent.

Is this something I should be concerned about? Or just a slightly annoying anomaly?

Thanks
