To make the point of the effectiveness of heat-treating the cylinder walls, the AERA-Engine Builders Association issued a technical service bulletin some time ago that warns engine shops about the potential for chattering as the carbide teeth of the boring tool pass over the hardened portion of the Duramax cylinder walls. With careful and routine service - and a mindful driver, I'd expect many more miles than is indicated by GM's conservative rating.
Perhaps at least K-miles? The plastic mudflap extensions show they spent a lot of time being bowed by the wind in hot weather.

If you want to know how long a Duramax engine will run, you should expect it to last as much as , miles before needing any major repairs. But, of course, this number can vary depending on how well the engine was maintained and driven throughout its life. While GM made several different generations of the Duramax diesel truck engine between and , some years were better than others for this particular model. However, there is nothing inherently wrong with buying new either because plenty of people do so every day without issue aside from price.
Driving Line also laid out each Duramax generation specs so read on! Older models of GM trucks that have the Duramax engine and Allison transmission are still valuable.
With arguably the best plug and play horsepower potential on top of hp being offered right out of the box , a stronger, six-speed Allison to back them, and an emissions-free engine last in its class. These trucks still incorporate ride friendly IFS, a quiet Bosch common rail injection system, and are very reliable. The to model years of HD and trucks featured a new body style, vastly improved interior, and the first version of the Duramax LMM engine to have an exhaust after-treatment process that required fuel for it to function.
With this being said, lower mileage numbers are present starting with these generation models because a more extensive EGR system is implemented, with diesel particulate filter and catalytic converter needed to meet stricter emissions standards established by government regulations.
The GM trucks are the most capable tow rigs. They have beefier independent front suspension, asymmetrical leaf spring design, and an LML Duramax engine with diesel exhaust fluid also known as Urea injection. Subtle to major issues surface due to added complexity of emissions controls and after-treatment systems. It may not display this or other websites correctly.
