My '99 F-150 has 124,000 on it and still gets 16 mpg back and forth to work. Ive see older E-Series vans with Triton engines with over 300,000 on them with no problems (one of them was a work van that had almost 500,000 on the original engine).
The days of vehicles being worn-out at 100,000 miles are long gone. If my brother's '92 F-150 can last 220,000 miles (and still going), my F-150 should be able to last 200,000 miles NO PROBLEM!

Thumbs up

My 97 f150 has 117,00 miles. The motor & tranny are in great shape. I'm having the usual problems associated with a old truckl. Its vacuum lines had dry rotted & many sensers have gone out. Other than this its been a ok truck. My old company van has over 250,000 miles now & its motor & tranny are its strong points. The vans body & front end are shot but the 5.4 runs great. Its still going around 500 miles a week with no problems

Except for fluid changes since the first tuneup isn't for 100k (which I'm less then 1000 miles away from) I'd say they're designed to go the distance.

I'm picking up a new F150 this week (hopefully, waiting on the bank to finish a home refi) and one of the reasons why is the continued reliablity I've seen out of the 5.4. Granted a lot of it has to do with proper maintenance, but that's not a big sacrifice to make considering the benefits, safety, and peace of mind you get from driving a well maintained vehicle.

I had a 94 4 cyl ranger, got 220k out of it. A lot of that was city mileage. All I replaced on it was the fuel filter, TP sensor, tires, and 1 set of plugs and wires.

My Grandpa's 78 Ford pickup got 336k before the odometer stopped working. He replaced 1 alternator on it. Before it just absolutely quit running, about 3 yrs ago, it never leaked a drop of oil or tranny fluid. I'm not too worried about any of Ford's products.

What does the IAC look like. I know it is an Idler Air Contrller. Someone gave me a description and there is like two or three parts on the engine that looks like it. On a 2000 F150 5.4, if I think it is what it is, it's on the right hand side of the butter fly valve manifold.

I'd be curious to know which grade of oil the 5.4's noted in this thread with high miles used. 5W20, 5W30, 10W30, etcJon

Mine was always serviced by Ford until I got it so I'm sure it had 5W30 in it all along. 102k miles, with another 1000 coming this weekend.

My '02 E250 keeps going.

Now at 219,000, engine still strong, no problems. Stay on top of maintenance. Best vehicle I've had in almost 60 years of driving.

Way to go!

Hope my 5.4 will go that distance as well. Using Mobil 1 5W-30. Mostly highway miles.
