on the 6.0 hey reccomend every 10-15k. if you dont get a speedy response here try the 7.3 forum.
the reason to change the filter is to keep good quality fuel and not put a restriction in the fuel system causing the pump to over work or have a pressure drop across the filter starving the injectors

the 7.3 is a little more tolerant than the 6.0... it all depends on how **** you are with your truck. the 6.0 injectors are alot more picky

I change mine annually - makes it easier to remember. Just put a note on my calendar as a reminder.
How long filters last has as much to do w/ where you buy fuel as much as the mileage. I buy fuel only at places that sell a lot.

Ford recommends 10,000 miles for severe duty driving or 15,000 for "normal" conditions. I just changed mine every 10,000 miles or once a year whichever came first.
