This my personal input. I have three Cummins power Dodge truck. 1991 with 340,00 miles. 1996 with 240,000 miles. 1998 24 valve with 170,000. and all are still going strong.
It all depends on the conditions in which you run the engine how you service it. if you do all your regular serviceing i have seen the with over 800k on the original engine and still going strong and i have worked at a Dodge dealer for 5 years. i have also seen some that have not been looked after not make it to 150k. with proper maintnce the engine will be the last thing to go on those trucks.
200,000-300,000
Most likely a 5.9 liter cummins turbo diesel 12v
Depends how well you take care of it , I have a gas engine from 1968 probably out lasted most diesels from that time . You get what you put into it just like anything else in life A diesel tends too last twice as long.
AnswerI have an 03' powerstroke 7.3 with 560,000 original miles on the engine and tranny, and she is still going strong.
Any diesel fuel is unleaded. There are summer and winter diesel in some countries. Diesel on cars work till 400000 - 500000km if the owner takes care. On ships it may last 50 years. If you are asking about a diesel engine running on unleaded gasoline (petrol) it will only run for a manner of minutes, if at all.
A well maintained car would last you 350,000km to 400,000km. But do expect to change a few parts.
200k miles is not a problem with normal maintenance.
They get great fuel economy. Diesel vehicles get 20 to 30 percent better gas milleage. A well maintained Diesel Engine is known to last a very long time. They are better for the environment because they burn less fuel.
Assuming it's properly maintained, there's no reason it shouldn't last 200,000 miles or so before any major service
