I would tend to agree with the above posts more so regarding the older mechanically injected diesels. However, the newer common rail fuel systems have a much higher incidence of injector failure. Certainly there are other failure modes than dirt and restriction, but if I had a common rail diesel I would consider performing a periodic injector cleaning as preventive maintenance, as well as considering extra filtration.
