Choosing the Most Reliable Diesel Engine Today

Are Duramax engines reliable?

Not only are Duramax 6.6l diesel engines highly fuel-efficient and more durable than other types of diesel engines, they also deliver more torque. This provides increased hauling capacity and capability, and is especially beneficial when crossing mountain ranges and during the course of long-distance hauls.

To date, aside from failing Duramax 6.6 engine fuel injectors, Duramax engines have had no noticeable recurring problems or failures. This incredible durability is one of the main reasons why these engines are endorsed by reputable associations such as EUROMOT.

As a matter of fact, properly maintained Duramax 6.6l engines can easily achieve a mileage of anywhere between 350,000 and 500,000 miles. One 2005 GMC has even remained in excellent condition even after 750,000 miles.

Does the 6.6 Duramax have a turbo?

It does. An engine is considered to be turbo if it's outfitted with a turbocharger. Turbochargers are cutting-edge components that allow diesel engines to achieve lesser emission levels, increased power outputs, and better fuel efficiency.

A turbocharger works by forcing more air (and proportionally more fuel) into the combustion chamber than atmospheric pressure ever could on its own. This boosts the diesel engine's efficiency by increasing the density of intake gas and thus allowing more power per intake cycle.

The sturdy construction and high quality of Duramax engines means that diesel engine turbocharger failures are not only extremely rare, but also easy to diagnose by any dependable diesel engine repair shop.

How much horsepower does a Duramax 6.6 have?

Like all successful industries, the diesel engine manufacturers keep improving their products and producing improved engine models all the time. It goes without saying that Duramax 6.6l engines are no exception to this rule.

Comparison of horsepower and torque levels in different Duramax 6.6l models:

  • 2001 - 500 lb-ft of torque and 235 horsepower
