That should not be stressed enough. The fuel injectors are probably the most finicky and problematic item on newer diesel engines.
One of the many ways the newer diesels try to control emissions is to ensure a more complete fuel burn. That's done by atomizing the diesel during the injection process. They achieve that by forcing the fuel through very small orifices at incredibly high pressures. On my Duramax, the fuel injection pressure can reach over 26,000 PSI.
The newer injectors are much more complex and highly engineered, therefore much more susceptible to bad fuel. Good fuel filters are the first line of defense. A frequent changing of the $30-40 fuel filter may save you the cost of replacing all the injectors ($3,000+). I have fuel filter changes at 5,000 mile intervals on my maintenance schedule.
