    in your experience (or someone elses) how many miles can a 6.6 be expected to run (stock no chip or under 10%) before you are looking at major repars?
    I'm looking at trading trucks looking specificaly for a 2001-2002 duramax and wondering if some of these relatively cheap fleet trucks are worth it or if i will have problems soon if i buy a truck with 200,000-250,000 miles on it.
    Will a 6.6 go 300,000- 4000,000 miles with average maintance before needing a major overhaul/rebuild/ replacement?

    I just purchased a 2002 duramax and it has 182,xxx miles on it and still runs strong, I also was leary about it before I bought it but after looking and talking to other owners I felt comfortable as long as it has not been abused

    A Duramax is a strong and reliable motor and will last a very long time if taken care of.
