Depends on maintenance. With the use of cheap, non-diesel rated oils and irregular oil changes 200,000 miles would be about all you could hope for. With proper maintenance, good oils like Shell Rotella T, or Amsoil synthetic, gentle driving, and a few add-ons like a good bypass filter and fuel water separator, 400,000 would be expected and 500,000 not unlikely.
The Mercedes petrol engine will last about 300,000-400,000 miles. If the factory maintenance schedule is strictly complied with.

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.
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.
some mercedes last 3 years but some expensive ones last 20 years
The Ford power stroke 7.3L diesel is one of the most reliable engines in production. Many will perform well over 500,000 miles.
I have seen 5.9L Cummins at 750,000 + miles. One I have seen actually had over 1,000,000 miles.
ANY engine (gas/diesel) lasts long as long u take a GOOD CARE of it, I just sold my 1997 camry with 363,000 miles on it and guess what? ORIGINAL engine, sounded like a DREAM. Good fuel, oil, and correct maintenance will tell everything. Due to the fact that a diesel engine uses compression to ignite the fuel rather than a spark plug they must be built much stronger than a gasoline engine. They therefore normally last much longer but they also cost more to build and buy.
