I can't recall how much fuel I had in the tank whenever I changed my fuel filters, but I do know I always filled up the main filter with diesel or some additives to ensure a smooth start. I used to use the clear pre-filters to judge how clean my fuel was. Changing them no sooner than 60,000 miles was not uncommon with clean, fresh fuel.
