Newer Dodge ram owners

I have an '06 and change the filter every other oil change; 10,000 miles. It's as black as sin when I take the old one out. Since I have a plastic tank, I assume the filth is from the fuel.
I imagine it's as important to change it on the newer trucks as well as it was on the older trucks. But $63 each and there are TWO??!! Yeow!! That hurts.
I'd follow the owner manual for recommended fuel filter changes. I'd also look into installing an aftermarket filter that doesn't cost as much to change and ahead of the factory filters in order to extend their lives.

I have changed mine twice going by the dash monitor. I went with the "NanoNet" filters at Genos garage. I also lengthened the front drain hose so it can be pulled down and reach a plastic bottle when draining. The sensor in the rear filter is removed and reused. Old rags, a lot of paper towel and a plastic trash bag help with the rear filter. The front cover will amaze you each time you remove it. Amazed that it didn't break even after being properly torqued. Genos also has good tech advice.

Diesel fuel is not nearly as 'dirty' as it was back 20 years ago. Now all gas stations are required to have fiberglass tanks, so you do not get the fluffed off steel, such as might have been found in a 30 year old tank that was installed back in the 60's.

Changing the fuel filter is normally not required that frequently now. Did you ever cut one open with a screwdriver to see if it trapped any dirt? Chances are it was pretty clean.

Yes I know - $15 bucks to protect a $15,000 engine. . Still it really is a waste of money to put that many fuel filters over a 5 year period.
