I'm glad somebody came out and said that. Thanks doug60!
Having these two fuel filters here side by side the WIX 33585XE & the Fleetguard FS19856 and they are one in the same. You can not tell them apart without looking at the stamped named & model # on the top of the filters.

 

Each to their own, but Baldwin Filters are the best. I would not recommend WIX to anyone.

 

I agree to each their own so what special data do you have that Wix are garbage?

 

They why do they have different ratings?

 

Wix is a quality filter, with crappy ratings. They run everything in nominal, which is 50% efficient.. I prefer absolute, 98.7% efficient.

 

The filter thing is a continuous my brand is better than yours deal. Just like oil and air filters, and inatkes, and every other thing we buy. Just change your filters regularly and you will be good.

well, I have been running WIX filters in my truck and all my race motors for years and have had "ZERO" filter related problems.

So who on the board has had an engine failure that was proven to be the fuel filters fault?

 

with a sub-standard fuel filter (especially if it's not properly removing water from the fuel) the likely damage would be injector failure. since injector failure is fairly common with the CR's, it would be pretty difficult to pin the cause of failure on the filter you're using, but i would use the one that has the best micron rating, that is without a doubt a water separator as well.

 

I have run Wix-Napa air/oil/fuel filters for years with no problems. Fleetguard filters are high quality but not the only option.
oil-7620XE (synthetic media)
fuel-3585XE (7 microns)
air-2846 (rated at 675cfm!)

 

Lets see who can tell which filter is which....One is the WIX 33585XE from NAPA the other is the Fleetguard FS19856_P from Gino's Garage

 

They have different ratings because , they are rated differently.
I believe that if they were both sent to an independant lab, they would both perform the same.
It's just the corporate world screwing with us.


Ratings
Pore Size Rating is the pore size of the filter determined by the diameter of the particle that it can be expected to retain with a defined, high degree of efficiency. Pore size ratings are usually stated in Micrometers (µm). Ratings can be stated as either nominal or absolute.
Nominal filter ratings are an arbitrary value, indicating a particulate size range at which the filter manufacturer claims the filter removes some percentage. Nominal ratings vary from manufacturer to manufacturer and cannot be used to compare filters among manufacturers. Processing conditions such as operating pressure and concentration of contaminant have a significant effect on the retention efficiency of the nominally-rated filters. (Example: Depth media, such as Pall Life Sciences Glass Fiber media.)

Absolute filter ratings are a value associated with a filter that represents the size of the smallest particle completely retained. Complete retention is within the experimental uncertainty of a standard test method consistent with the intended filter usage. Among the test conditions that must be specified are test organism (or particle size), challenge pressure, concentration, and detection method used to identify the contaminant. (Example: Most membrane filters, such as Pall Life Sciences Supor membrane products.)

 

So because they look the same they must be the same???

If they were the same why would Dodge put out a statement that the fuel filter MUST have a 7 micron absolute (98.7%) rating, then either change the rating form nominal to absolute (based on who makes it), or WIX sell it as nominal.

Like I said, WIX makes a quality filter, they are of good construction, just lack sufficient filtration for my standards. Even there oil filters don't match up...

So are you willing to chance an expensive fuel system on a filter that doesn't meet OEM specs, when TSB's like this.. for a couple of bucks every 15K?


The FS19856 is the same filter as the FS19800E, just has a ULSD compatible o-ring.


That rating statement sounds like WIX BS to sell sub-standard filters. Why would they go out of there way to cover their nominal ratings when all other filter companies use absolute, and the OE standard in absolute... unless they are selling sub-standard filters.... you know the old saying, looks like a duck, walks like a duck, quacks like a duck.....

Run them all you want. I have run them before and they are fine in a pinch, but not something I would run on a regular basis.

If you think they are the same then send them to a lab... The only corporate that has influence on how WIX advertises is WIX, so why would hurt themselves?

 

My truck is a 2004.5.
Ive been following filtration since then.
If you do some more digging you will find that about 4 years ago.
Bosch recommended 5 micron fuel filtering for the common rail.
Dodge went with 10 micron.
The 7 mircron still falls short.
I run 3 mircron water/sep before the pump
Into the stock canaster / 10 micron
Into a 2 micron /water sep before the CP3.
I didnt wait for a TSB to tell be what to run.
Sometimes you have to read between the lines.
I confident in my filter choices.

 

I was going to switch to Amsoil fuel filter because I use their oil and oil filters. However their filter was backordered and glad I didn't use it. They are MORE expensive (even at preferred customer pricing) then the 7 micron from Cummins, not a lot by still it's like $3 less. So i'm sticking with the filter from Cummins. I don't run my fuel filter long anyways, maybe 8k miles max.

 

What filters are you finding that are 2 and 3 microns with water sep? The best rated F/W I have seen is the 5 mic baldwin, PF7977.

I do agree with you thou, which is why I run a 20 mic F/W, 5 mic F/W and a 2 mic. Thou I had read Bosch wanted 2 mic... which I guess the new Duramax has, and a REALLY small filter.. so it only lasts a few K.

Amsoil doesn't have their own fuel filters, its a WIX... so your better of anyways.

 

I was going to say 2 but I cant remember that far back.
33005 Wix 3 micron
The 2 micron is a Perma cool 8100
