23,000 miles to date.....average 15 mpg......city, winter fuel, some short trips.......doing the same with my 2000 Yukon XL, I was just under 15 Mpg.

I took a day trip from Boston to New York last week......72 MPH on cruise......29 MPG for 475 miles.....

No problems whatsoever on anything on the X5
