I have about 235,000. and still runs like a champ, but we don't push it too hard and use mobil 1.

I have a 2001 with 225,000 on. It's an everyday work truck and personal driver. Rebuilt the tranny and put a new clutch in it, runs great though. My mechanic has an 02 with 460,000 on it!!!

I have a 2002 4.2 with 230,000 miles on it all it's had done is intake gaskets clutch and alternator. By far best truck I've ever owned, I'm a mechanic and sad to say I neglect it every single day and she just keeps goin been waiting for the motor to go kind of disappointed she hasn't ready to drop a fresh one in and tweak her up a bit. I'll never sell my old ford.

125K on ours. I'm planning in the future to replace the intake isolator bolts and clean the intake runners and EGR ports at the same time. Other than that, it's running strong.

I was getting near 200K when I got rid of mine. The engine was still running strong, the body was rusted too far along to keep it.

Holy cow! I would have to be 300 years old to rack up that mileage on mine - it only has 17,500!

I'm at 158,300. Engine seems very strong although I've been working on some intermittent drive-ability problems. I'm sure I'll overcome them soon.
