I advise changing the fuel filter every oil change or at the least every other oil fitler change. Yes it adds to the price of service, but if it can extend the life of the injectors its worth it. I also do not buy filter from the parts stores, there are places to buy filters from in bulk for a lot less money then buying them when necessary from the parts store. A fuel additive like Howes Lubricant or Power Service, or purchasing a Biodiesel(preferably Soydiesel) will help lubricate and extend the life of the injectors that have very tight tolerances inside them.

Old Caterpillar Equipment used to say "Buy Clean fuel, Keep it clean" on the fill cap. Its more of a necessity then it ever was back then.
