The highest kilometer 7.3 I know of in my area is 400,000kms (249,000 miles) which is reaching the upper limited for the lifespan of the 7.3. When you have a truck that spends all its life on the west coast the truck is always pulling or decending grades. A grade less than 10% is for sissys

A 7.3 or 6.0 or Cummins seeing over half million miles is the biggest frigging laugh. That is 800,000kms there is no way the truck will last that long you would have rebuilt the truck 2 times.

I will keep a truck till 300,000kms (186,420 miles) because the truck is worn out. There will be a laundry list of stuff need replacing or rebuilding. The engine is on that list doesn't matter if its gas or diesel. The average person that uses their truck daily puts on 20,000kms (12,428 miles) a year.

When I buy a diesel truck I always plan on doing engine repairs when the truck reaches the 200,000km (124,290 mile) mark. You can count on a PSD rebuild costing 7-8 grand CND.

Ya I own a diesel I don't plan on resale value. I buy a diesel because I want one. The fuel economy is a little factor but the trucks I buy are heavy so getting 12mpg is what I usually get.

Choose what ever why do you have to justifying a diesel. If you want a diesel buy one.

The V-10 will do the same job your climbing the 10% grades with a trailer the same speed as a PSD.

 

There are many, many 7.3 owners in that forum with over 500k (MILES), and several that I've heard of over 1 million. None have been rebuilt. You can call it a laugh all you want, that don't make it that way. My father in law had over 400,000 on his Lincoln Town Car with a 302. The only thing done was the front of the motor (timing chain, water pump, etc.). Engine still ran like a beast and burned very little oil. International built the 7.3 to be a high mileage engine, that's why they're in school buses, garbage trucks, etc.

 

Oh please, that's for sissys. I put on(in a slow year) 30k a year and those are hard hauling miles(most on the highway, but still that's pulling at the min. my small 12.5k horse trailer).


Shoot, you must have had some bad trucks if your expecting to do an engine repair at 124k, I have had numerous trucks last long after that and with no engine repairs. Even my girlfriend's cavalier(which has a crap engine in it) has lasted(and is still going) at 200k without engine repairs and I promise that engine wasn't designed for longevity.

 

Holy cow...I'm doing 30,000 MILES a year in mine.......

 

Let's just keep this civil It was going so well ...

 

i have a 6.9 with over 300,000 diesels will run forever if they are maintenanced right. A diesel truck may be higher in price but they will run forever and pull anything you put behind em.

 

Your not the only one.

 

I put down just over 20k last year myself...

EDIT: Oh, and sorry fellas -- had to raise the BS flag on that one.

 

Hey, you know what they say: "if it quacks like a duck..."

 

I've got 14,500 miles on mine, bought it first week in May 2005.
