OK, none are f150's, but you might want to hear them anyway.
My moms boyfriends econoline has over 400,000 miles on it. I think it's a 98, i'm not sure what engine or anything. He's an air conditioning man, so its completely filled all the time(couldn't even get a door to fit in it), and it's his only vehicle. Never had a problem with it. His van before this was an 86 ford, he has no clue how many miles were on it, the person who sold it to him just said its rolled over once or twice. While he had that one, some how it ran out of oil and over heated. One of the valves were stuck for a little over a year when it finally blew a rod. He always says, just treat your car like a woman, and it'll last for ever.
Oh yeah, my brothers 86 ranger has probably 150,000 miles or more. He blew the speedo(and odometer) on it driving way over 85, the only problem is his pedal has only two positions and the engines always way to loud for some reason I guess. He towed a full size chevy van that got stuck in a ditch with a bunch bushes, the entire area was a sheet of ice. My next vehicles gonna have 4wd :).
My escorts not a truck, but at least its a ford. i've had it almost completely run out of oil twice and it never over heated. My first stupid mistake i'll never do again was forgeting to put the oil cap on when I changed my oil. After about a week I couldn't figure out why it always idled around 2000 rpms, so I looked under the hood and saw it was missing. I'm sure there was some oil in it since the light never came on, but it didn't register on the dipstick. My second dumb mistake was not having the drain plug on tight enough, and I guess it got knocked off becase I was driving home and one of the spark plugs had come loose and made the car shake real bad. Right as I pulled into the drive way, the light came on. I shut it off right away, and saw the trail of oil. I followed the trail of oil for a little over two miles to get my drain plug that had been run over a few times. Put some oil in it, put the wire back on and it ran as good as new. Yeah i know I was stupid to let those things happen, but atleast I'm learning when I'm young on an escort. Its got a 140,000 and the engine and tranny are perfect, except for the 1st and 2nd gear synchros. Not to mention I charge down the highway in 3rd going 70 just to see how fast people move out of my way. I think I have the same problem as my brother.
