Today I ask the same question to a injection company and thay told me every other oil change!! I wasn't having any problems. I was just calling to see if
diesel fuel could contain a bacteria in it and would fuel additive improve my fuel millage, They said yes to both but the bacteria would apear black in the
fuel filter holder and would require a different additive. I told them that their was rust in mine and they said that it needed to be cleaned and new filter change. also said that the filter housing is 500.00 to replace if neglected. I look through my owners service guide and the normal change is at 30000 mi. severe change at 15000. call ford for a filter and they told me $54.00 nearly had a wreck! somewhere on this site someone posted that International sold same filter for less. When to the international house and sure enough same filter for 14.09. different box but same exact part. This just blows me away!! thay had four of them and I bought all four for just 2.00 more then I would of paid for one at Ford. They also said to change the
fuel filter every oil change or no more then the second oil change. While I was there ask if the air filter was the same he said yes $11.20 bought two of them. you will pay 29.00 each at Ford!! Not going back to ford for any service parts.
OIl filter is also the same. From now on 5000 mi I will replace
fuel filter and every fill up will get the additive.
Paid way to much to neglect a 14.09 fuel filter.
