yeah keep it maintained. i had an 01 f250 4x4. it was my work truck. never got into the motor and it had 276000. it would still tear the tires loose from the pavement. used about a quart of oil every 5000 miles. had the trans built at 197000. now i m working with a 99 f350 that wasn t maintained very well:dang:

We have one that I service at the shop that has 300k on it with no real problems. It even got totalled out once when it was hit by a plane. :D Im serious Still going strong

my 2000 has 142,000

My '01, 7.3 has 399000. Runs great.

oh wow jam thats awesome news!

my 2000 has 316k and still blowing smoke :yeah:

Update. Ran up to North Dakota, just hit 400395. :tu:

The guy next door had a 95 F-350 that he used/abused for a construction company that had 450K +. It was used very hard but very well maintained. He replaced a tranny,rear end, and transfer case but the engine was never apart.

my 1999 has 299,431 miles still lins like new no leaks no problems the only thing i replaced was turbo and a few sensors im not easy on it either i just take care of it. still has the origional tranny never been rebuild 6 speed stick. And thats why im a ford man

Yea every 7.3 i have been around has been a good one never really heard of any short lived egines if taken care of, only other option for a long life engine is the 12 valve cummins either way they both are bullet proof in my book.
