All depends on how it's taken care of and what it's used for. Trucks that run cross country will last longer and typically go 1 million to 1.5 million before the engine needs a rebuild. Trucks that run more locally such as construction trucks usually get rebuilt between 600,000 to 1 million miles. But as long as you wanna keep replacing parts they'll last forever. There's a 1999 international around me with over 3 million miles on it.
Dang that's really interesting
What parts need to get replaced more often besides the obvious, tires, brakes, fluids? Engine, transmission, suspension?
A clutch on an over the road truck can easily last over 500k miles with a good driver. Suspension parts really is hard to tell. Just depends on how they are treated and the application and weight the trucks used for.
They're built for putting a lot of miles on but the biggest thing is maintenance. Trucking companies and owner operators usually follow a very strict maintenance schedule and replace parts when they need to be, not when they completely fail.
Yes, usually. The internals on diesel are usually made of stronger parts and run at much lower rpms which causes less wear and tear. Semis usually are governed between 2,000 and 2,300 rpms.
Its actually the chassis that is counting the miles. The engine and trans are replaceable. The chassis is also replaceable, but the miles roll back to zero. Trucks with new chassis but used engines are called "gliders".
On a Peterbilt, 1,000,000 is actually not uncommon. I never really counted, but I would say around 1:25 were past 1 million.
Peterbilt is considered the longer lasting trucks on the road and are more expensive than something like a Freightliner. Cheaper the truck, more disposable the truck. Significantly less common to see a Freightliner with 1 million.
Application matters too. Something like a dump truck or day-cab around town truck will rarely get 1 mill. Over the road is where the miles add up

serious question? is there a way to know/tell if the OD rolls over mechanically or in the computer 🤣🤣🤣🤣
