Has your diesel truck suddenly lost power or feels like it won’t accelerate like it normally does? If so, your truck may have entered what’s known as derate mode.

Modern diesel trucks are cleaner and more efficient than ever before. But that cleaner performance doesn’t just happen inside the engine — it’s largely due to the exhaust aftertreatment system working behind the scenes, including the DPF (Diesel Particulate Filter) and DEF (Diesel Exhaust Fluid) systems.

Diesel engine services can do wonders for your truck. From an old truck that needs some TLC, diesel engine service can turn it into a truck that can compete with brand new trucks.
