How Reliable Is the LBZ Duramax?

The LBZ Duramax is one of the most reliable diesel engines GM has ever produced, known for its robust build, impressive power, and minimal emissions restrictions.

With its strong internals and lack of a diesel particulate filter (DPF), the LBZ offers excellent longevity and performance. However, like any engine, proper maintenance is key—regular oil changes, fuel system care, and monitoring injector health can extend its life. Looking to enhance or maintain your LBZ?
