Turbocharger

The turbocharger increases engine power by pushing large amounts of air into the engine’s cylinders.

The finned parts inside the turbocharger turn at extremely high speeds and are subjected to extremely high temperatures. They are lubricated and cooled by engine oil. If the engine oil is not replaced at the specified intervals, the bearings may seize or emit abnormal noise.
