Fuel filter last more than 14000 miles

Had my fuel filter changed today and it had more than 14,100 miles on it. No problems with it.

I take it that it is the OEM Filter? Did you happen to cut it open and see the insides? That's not too bad, 14K.

What's the recommended interval? Wait for an 'idiot' light?

I think the recommended interval is about 7500 miles or so.

255k+ on mine and only changed the filter twice

A little too long for me, but if it works for you, that's good.

Last time before was about a 13000 mile stretch. I did not get to cut into it. Been running Standyne, but apparently my fuel has been pretty good. Some reason I thought GM recommends every 15000 miles, maybe not.
 
So long as you are monitoring with a DP gauge or fuel supply gauge there really is no reason to change a filter until it is needing to be changed, bad fuel can happen any time mileage does not come into play so long as you are running quality fuel unless the filter media has a life limit, is inferior, or a defect in the filter itself fails mechanically in some way there therotecially is no reason to change it.
 
FF life monitor on a DMax is 15k and every one I've cut open at around that mark is pretty damn dirty. I usually change between 12 & 15k. It's a 2 micron unit so it doesn't take much to restrict it. They are pretty pricey but far cheaper than any of the downstream components.

X2 on life being 15K and being dirty. Mine was while towing over 50% of the miles. Always carry a spare fuel filter as they can plug anytime. I wouldn't push a filter much past 15K as GM redesigned them several times to help prevent injector failure. Maybe you are getting lucky with clean fuel, but, this is the exception rather than the norm as most diesel isn't that clean. Some of my filters didn't make 500 miles before plugging.

I pushed the factory 2008 air filter to 50+K miles and the result was the filter imploding and letting dirt through. The redesigned air filter has a plastic "X" on it to prevent filter implosion debris from going all the way into the intake tube.

You guys are right. I must have been thinking about the oil interval, not the fuel filter interval. Sorry for the confusion. I always changed more often than necessary just to be safe anyway.
 
Yeah, I bet the No. 1 fuel cleans the tanks and keeps the lines flushed better. Seems the Kerosene I have seen is pretty clean. The pumps are probably filtered under the hood of the pump housing???? I have seen some pumps being worked on and they had a filter. Seems more stations subcontract the pump maintenace today vs years ago. Warmer climates the fuel also seems to drop out darker "sediments" from the fuel getting much warmer I think its asphalt ???? derivatives of the fuel.

And I also can imagine the dangers of bad fuel up there causing life endangerment (or at least a really really bad day) such that stations avoid the stigma of a bad fill as best they can.

Doesn't GM recommed 15K miles or once a year for minimum maintenance. I totally agree on bad fuel being kinda random but can get you anytime especially if you travel and happen go to a poor station without knowing it.
 
FWIW, I change the filter on the Duramax yearly, works out almost perfectly to 15-17k. Just did it the other day, and this thread reminded me I have to go reset the idiot light, LOL.

Herein lies the problem, a 2 micron filter only is too fine for an all in one setup, GM in it's infinite wisdom to protect components and save a buck went with solo filtration which means that it has to be changed far too frequently, the 2 micron particulate that comprises fuel is not that much, but since the single filter catches all above 2mic all of it gobs up the filter at same time completely plugging the filter faster, I don't know if the OEM filter has a built in bypass but if it does and since DP is not monitored on the filter , you are dumping raw fuel to the engine direct.

With a dual or even a 3 filter setup of ever decreasing size you aren't early heavy loading the single filter, Racor, Baldwin, & Wix engineeiring who I talked to say more filters the better overall let a large 20 or 30 micron do teh heavy work as that is what you will find the majority of your trash to be sized at. Not having real estate for a 3 filter setup , I went with a 2 filter setup, got a good deal on a Racor Marine setup "on the bay" to act as my 10 micron nominal primary, but any filter say a generic "goldenrod" diesel fuel filter (gas filter won't work) from tractor farm or other farm supply would work also and inexpensive, feed that into your expensive oem style 2 micron for Dmax 5 mic on 6.5s.

The Nicktane Cat filter IMO is just a bigger trash can bucket able to hold more garbage than the GM one, save some coins and plumb in a prefilter. Another risk is that when filter media gets fully plugged and if you have no way to monitor the DP across the media the you can "hole" the filter and the raw fuel makes it's way to the downstream fuel system and the media itself can become a contaminant as the media shreds.
 
I do not think that the OEM GM fuel filters are 2 micron. I thought they were 10 micron. I run 2 nicktane setups in my 2006. I run 2 micron CAT tall can on the rear, and run the CAT 2 micron short can in front in place of the OEM filter. I change the rear filter every year, and the front filter every other year. I cut the cans every time, and there is never any evidence of a problem, or any issues with them plugging up. I go to the same station every time to fuel up. And I run fuel additive in every tank. I have not had any fuel related issues as of yet.
 
The original GM (Racor) filters were 5 micron. Somewhere around 2 years or so ago they went to 2 micron. I suspect that had more to do with LB7 injector problems haunting them than anything else. I''ve run nothing but the factory location, Parker/Racor replacement filter for 205 k and 40 k before that on the LLY with a grand total of 1 problem and that involved gelled fuel at -25* ambient. So no, I'm not at all concerned about the FF design at all.
 
True Mike. :thumbsup: I remember reading that the OEM's back around 2006/2007 were 10 microns. But I could be wrong.
