The highest mileage one I had was a 95 with 290K miles. I bought it at the auction for parts. It still ran strong, but the tranny was slipping. I get a lot of them now with over 120K miles. It seems that as long as you don't over heat them they will last a while. From my experience, the Zetec is a much longer lasting engine than the Duratec. I've only had a couple of Zetecs with less than 100K on them with any major engine troubles, but I've had quite a few Duratecs with a mess of different terminal engine problems with less than 100K. Go figure!
