I have a 95 Dodge 12 valve diesel and the owners manual recomends changing the fuel filter every 12,000 miles. I think that is excessive. What is a realistic miliage change interval for a fuel filter on this engine?

 

I usually run mine around 15,000 or when I notice a loss of fuel pressure on my fuel pressure gauge.

 

It's not miles that determine when to change it, it's fuel pressure.

I have had to change mine as soon as 2,000 miles and as long as 10,000.

 

Personally, I generally do the fuel filter at around 10k. It is quick and easy, and not that expensive.

The quality of your fuel source, and how clean the tank is probably also have a good bit to do with how long they will run before getting restrictive.

 

easy.. every 2nd oil change..

that way you do not forget and can just do it while doing oil..

 

Every oil change. Cheap insurance and I get the Baldwin 7977 Filter for $8.

 

15 to 20k for me, been good so far.

 

Wow that is cheap. Just paid $28 for a WIX. Every other oil change here.

 

$28? Youch. Is that for the 6.7?

 

Every other oil change for me.

 

Every 10K or whenever I see a drop in post-filter fuel pressure.

 

I usually change mine in September and then again in the middle of winter when it gells on me.....

 

Every other oil change here too.

 

every 2 years or 20,000 miles, whatever comes first actually i check my fp and if it seems low i change it.....the last change was over 2 years ago

 

I change both my fuel filters every other oil change.
