I sold my 1999 F-250 7.3 to a friend & it had 175,000 miles before it got stolen & destroy.

 

Sorry to hear about your loss but I am look for trucks with over 300k.

 

301k on mine no real problems

 

Both my 6.5's have over 300k on them. The 95 has 302k and lost its first trans and my 94's odometer quit working right over 300k miles ago.

 

I know of two 1994 F350 Crew Cab Dulies with the 7.3L IDI Factory turbo with over 300,000 original (even the factory crushed down pipe) miles on them.

Mine's not going to make it, oil pan gasket, and valve cover gaskets leak.

 

Current truck 430,000 miles with original turbo and hg. Sold 2000 GM 6.5 with 520,000 miles great results on oil samples and still running strong ALL original except ip and 1 trans, I was tired of replacing ip's.

 

I know of 7 dodge diesels that have over 300,000 miles and have never been opened up.
My old 85 Ford 6.9 diesel has 234,xxx and the speedo hasen't worked it 12 years so I am sure that is well over 300,000 Biggest repair on that motor was a intake gasket caused from overheating the engine. Runs good uses a little oil but outside of that its cherry.

 

I have my 95 CTD with 368k on it. Pulling the motor this week for the first time. To change all the lower gaskets to stop oil leaks. I think the KDP got the front cover as it just started leaking bad.

 

My 99 just cracked 330k yesterday

 

I'm a daily driver of a truck I bought new, It's an 05 with 266700 close to 300. Pan and head never been off of it. Oil changed every 5000 miles along with air an fuel filters several times in between the oil change. I just sold an 06 with 240k. I believe anything you properly maintain will go for as many miles as you want.
