11,000 miles with no problems other than 2 dealer recalls. I have noticed that my 2.5 tends to use a little oil, a little less than a quart between changes at 3 to 4k intervals. So keep an eye on oil level. I have also heard that Purolator or Motorcraft filters might be best for the 2.5 duratec due ot the presence of an anti-drain back device. No big deal as Purolators are easy to find and generally only about 1 or 2 bucks more than a Fram. Other than that, just a lot of fun driving.
