This answer was rated:

What is the averag life expectancy of a duramax? What type of problems would be expected at 261000 miles? How could you maximize totalfuel economy? Whats would the pros and cons be of a desiel vs gasoline engines be?

Greetings and Welcome to Just answer.

It is not uncommon for a Duramax to go 400000 miles plus with proper maintenance. I +have seen several that were used for RV hauling with 500000 + and going strong. Adding a chip or driving it hard will not lead to a long life.
