My dd is a late 99 f250 4x4 7.3l with 274k on it as of now. It has 3.73 years and the 4r100 auto trans. I get 15mpg average, but I have gotten up to 18mpg on long trips empty. The only weak link on the 7.3 is the 4r100. Mine is still factory original and still good, but my truck never pulled over probably 6k lbs before I bought it at 234k, and was never ran hard, and the guy had the dealer take care of any little issue. He even took it to the dealer to get it detailed. I had a friend that worked at a ford dealer and still have one that does. They say on average the hot shot guys go 200k on a 4r100 and 1 million miles before rebuild on a 7.3 if all has been serviced well. The only 7.3 from 99-03 that has any issue is the 02-03 if they are hopped up a lot because they changed to powdered metal connecting rods in 02 and they are not as strong, but no need to worry if you leave it relatively stock.

I'm knocking on 300k in my personal truck, and it doesn't use or leak a drop of oil or fuel anywhere. I helped my friend move his tools when he quit the ford dealer, and that specific truck was actually in the shop. It was a green crew cab f350, a 99-01 model, that the back seat was converted into a sleeper. The truck had 1.2 million miles on it at that time about 9 years ago. I would go to the dealer and send you a printout on that truck, but the dealer has been bought out and moved since then. It had a new factory trans every 200k and the motor was replaced with a factory reman at 1 million miles and no telling how many hrs as he also slept in the truck. Will mine do that? Probably not because I don't run the highway in a pickup for a living. Could mine make it that far? I would think so. If you take good care of a good product it will last a long long time, but you might not be able to grasp that as GM has yet to make a decent Diesel engine( the duramax is an Isuzu and it has had its share of problems like head gaskets and injectors just to name a couple). I am glad that I mad you laugh though. Means you probably had a better day than mine. And just so we don't leave anything out, the cummins 5.9 is a proven million mile motor if taken care of. I realize many will not understand how a motor can last that long, but go talk to some truckers that drive 100-200k a year and ask them how long a well maintained diesel will last.

red chevy comes from my first pickup a 1/2 on with a 350 cid. I have nothing against a d-max but im very far from hung up on them too.

7.3 is a good motor will last a long time if cared for no doubt the part I laugh at is averaging 1,000,000 miles. Sure a few make it but it is no where near the average... more like the one in a million

If it weren't for the fuel economy I would not have bought it.

Maybe I used a double neg, not sure.

25 mpg was my cut off. If I didn't think I could average 25 back and forth to work I was going to buy another car. I feel like the price to buy a ecodiesel or any other none base motor option 1/2 ton is somewhat comparable. Im definitely saving some money on fuel, and while there are some other higher cost associated with it, such as oil changes you can do them pretty reasonably if you do them yourself. I was chaning my oil at 5k in my 5.3 and is what I would do in any other gas half ton. Ram requires some spendy hi grade oils for the ecodiesel and recommends a 10k change interval not sure if I will follow that yet or not, but will likely push it further than 5k.

I know of a coupe 6.0s 300k never been worked on. The truth it ford 6.0 was first
Diesel with emissions ford tried to get ahead of the new emissions laws coming out. It was a learning curve. But look at them now. 6.7 ford best diesel out
