How often should I change fuel filters?

Like RAS42 says, cheap insurance against injector damage. I change my fuel filters at every other oil change, and don't forget the transmission fluid change either. 30K miles for regular service, 15K miles for severe service such as towing. Mercon SP/LV is now available as a generic instead of being only available at the Ford dealer, still pricey at $6 a quart with the 5R110 automatic tranny taking 19 quarts to flush and fill.

I replace every other oil change so 6k it is, and I run syn oil also. I have a lift pump (AD2-165) with a water sep and filter and replaced the factory position with a adapter and I run a CAT filter in that position also. cant have enough fuel filter IMO and the fuel need to be clean because you never know when you get a bad batch

From memory, I think Ford revised their manual for that engine and now requires every 5000 miles for the 6.0 liter...had one and did it all the time. Check one of the Powerstroke websites. That engine is very troublesome.

Ford's recommendation is to change the fuel filters at 10000 miles if towing. That is what I do with my '06 F350. No fuel issues!

It's usually a really good idea to follow OEM specs on maintenance items. IOW what does the book that came with your truck says about changing your fuel filters? Any more is usually a waste and any less is usually a danger.

Something that many people don't understand is new filters don't filter better than old filters. In fact it's the other way around.

From some of these posts on here I'm beginning to see why people say diesels are so much more expensive to maintain. :R

Change mine every 10,000 miles. I would not let go past a year though. Cheap maintenance.

I have a 06 PSD, drain the filter on the rail in a cup.if you have no water and fuel is clean I would not change it.Your IH dealer has the filters for 50.00

I change fuel filters every 15K miles, second oil change, but I am very careful where I buy fuel.

my local station, I have reviewed their tank check schedule and it appears to be up to std. The local ambulance system buys fuel from this station and has had no fuel related problems.

on the road, I buy only from major fuel station, where the 18 wheelers buy, because just one batch of bad fuel and those truckers get bad fuel, your station would be on their list in about one day, as having a reputation for bad fuel, you would be out of business.

also I use only Baldwin fuel and oil filters

I change the 3 fuel filters in our Sierra annually or every 10K whichever comes first. As for the ole Dodge, she gets a new fuel filter every 25K.

Happy camping!!! See y'all down the road!!!:)

I change each summer and around 6000 miles.

Depends on your fuel. I'd at least drain the filter on the frame rail under the drivers seat, takes a 6mm allen. I had a 2005 6.0, at that time they recommended 15K on fuel filters, IIRC. They'll be black at 15K. The frame rail filter isn't too bad, and the secondary filter on top of your engine next to the oil filter is easy.

Go to an International dealer and buy your filters there. Exact same thing, half the price. Ford wanted almost $80 for the filter set of two, IH was $32 the last time I bought them a few years ago. Probably about $40 by now. You'll have to do a little research to get the IH part number, they can't help you if you go in there and ask for fuel filters for a Ford 6.0.
