So I just got home from a long trip, 1450+ miles. I had to replace both O2 sensors when I got home due to 1/1 stuck rich and thus throwing 2-3 codes. I figured I'd change the fuel filter since I was doing maintenance. I bought the truck used, and did not know what fuel filter was in there. I went to the dealer and bought a Mopar fuel filter. I figured I would have gotten the MOPAR 68157291 NANONET two stage fuel Filter (5 micron outer/3 micron inner), instead they gave me the MOPAR# 68065608AA (5 microns at 98.7%) filter. The one they gave me has the two filters, one inside of the other. I'm not sure what the exact differences are between the Nanonet and the one they gave me are.... ? I read the Nanonet filter is the better filter. I removed the filter that was in there when I bought the truck, turns out it was the single filter style WIX# 33255 (12 micron at 100% / 5 micron at 98.7%. Filter looked good. Normal fuel color on the outside, and super clean filter media on the inside, so I assume there was not many miles on it. Glad I swapped it anyways after reading some bad reviews about WIX not filtering water out and not meeting Ram/ Cummins spec.

Couple questions...

Why did the dealership not give me the Mopar Nanonet filter? I suppose the dealership feels the Mopar 68065608AA is good enough for warranty?

What is the main reasons to go with the Nanonet vs. the Mopar filter they gave me?

They did tell me the filter was going to be $86 +/- but they gave me a car club discount around $68 for the filter.

Not sure why the dealer gave you what they did. Maybe they did not have the Nanonet filters. Here is a link to Geno's garage with fuel filters. Geno's generally beats dealership prices, even with shipping. Geno's is top notch to deal with. The Nanonet filter has a lower micron rating. Dealer may have thought, you would not know the difference.?

I know geno's have them, and which ones are better. I expected the dealer to give me the better filter, but I did not know the part number difference until I got home. Maybe he wanted to clear out older inventory? Maybe he did not know any better. I have seen the nanonet filters listed for '13+ trucks, maybe he thought they only fit the '13+ trucks, and is not the correct one/ better one for my '12. Honestly I think he just did not know any better. For the last few hrs I've been looking up all the micro differences and such and can't find the micro limit for the filter they gave me. I know it has two filters, but I can't find what each filters down to? I'll buy them from Geno's from now on, as they are cheaper, and I'll get what I want. I swear the customer has to be the parts expert, the labor guru, and the warranty enforcer. :banghead:

For this first fuel filter change I wanted to go back to the dealer for 1: it's on file I bought the filter there. 2: I wanted to see what they wanted to charge retail for them, and with the car club discount. Still a rip off. No surprise there.

Correct you are. Many times the owner is MORE knowledgeable than the person behind the counter. Like the car parts commercial, the parts guy taps on his key board, and you hope he gets you the right part???? Unfortunately, many dealers place their 'bottom line', ahead of customer satisfaction.

Do you know the micro limits of the two stage Mopar filter they gave me? #68065608AA

I just see the 5 micron at 98.7%

I assume that means, at 98.7% capacity it is still filtering down to 5 microns. What I can't find is what each filter micron is. I assume the inner filter is the 5 micron, but then what is the outer.... 10, 12 micron?

MOPAR 68065608AA fuel filter: It is a 5 micron filter, and that is all that Geno's catalog give for a description. I have used the FS43255 Fleetguard fuel filter, which is also a 5 micron rating. Now using the Mopar 68157291AA Nanonet filter. In an article in TDR magazine, the Mopar Nanonet filter is the same as the Fleetguard FS53000 Nanonet fuel filter, just a bit lower in cost. (hope I typed that correctly, Bi-Focals, you know)

Found this, it might help: https://www.cumminsfiltration.com/html/en/about_us/newsroom/corp_news/corp_story62.html

I see Genos has the nanonet Mopar filter cheaper then the Fleetguard, so the next time I'll just buy from there. Like I said I wanted the dealer to have it on file when and where I bought a fuel filter at. Less dealer questions later on. However since they can't give me what I expected to receive, especially since they said retail was around $89 (which is also why I expected to get the nanonet) they can keep their extremely high price lower quality parts. I'll stick with Geno's. When I was at the parts counter I opened the box and seen it was a two stage filter so I thought I was getting the nanonet filter.... upon closer internet picture searching the nanonet filter has a blue color inner filter media. Lesson learned I guess.

have you read or seen any mpg difference with the different micron filtering filters? The WIX was in the truck when I bought it and I regularly see 14.8-15.2 mpg mix in town/ hwy, and I got 17.1- 17.5mpg on my 1450 mile trip. Seems better then I read for a full emissions '12 truck.

No, I have not heard about mpg differences between filters. A new filter would be less restrictive than one that has been in for a while, IMO. Have you looked at the dual filter kits? I have the Cat/Cummins Dual Filter kit, and so far, I am well pleased.

Yes that is the one I believe I am leaning towards buying. I thought about buying the Mopar severe duty kit, until I just read a thread that all those replacement filters are on back order/ not being made anymore. Leave it to Fiat to make such good decisions :banghead:

UPDATE:

After alot of searching I came across a Cummins site with lots of good info. One such important bit of info is that Cummins now recommends Nanonet filters be used. So I would venture to say that Cummins may not warranty any fuel related claim filed if they find any fuel filter used with out nanonet technology.

Looks like I'll go back to the dealer and ask them why they are selling me (anyone) a fuel filter for a Cummins 6.7 that does not meet Cummins fuel filter spec. :spank:

The dealer will sell you whatever filter came in the truck stock unless you specify otherwise. I will suggest to the customer the upgrade options for any given filter when I am selling them.

Cummins doesn't deal with the warranty on Ram engines at all. Chrysler/Fiat purchases the engines with no warranty backing from Cummins. Have asked our Cummins Rep. about warranty issues and he has told me to get ahold of the Ram dealer.

You sound like you work at a dealership.

I was talking to my friend ,who is a salesman, and we were both sitting at the parts desk when I asked for the fuel filter. I was explaining to my friend how the fuel filter is a two stage filter, outer filter down to 5 microns, and the inner down to 3 microns. I was explaining to him how important fuel filter were on these new diesels. He is a car guy, and doesn't know much when it comes to trucks. All of this was in front of the parts guy who was shaking his head in agreement.

Like I said lessoned learned. Just another example of how the end user/ consumer needs to know everything from buying/ selling, to repairs, to warranty, to parts, to service. It doesn't matter which field or expertise is involved. I did not know the part number of the nanonet filter, I knew to look for a two stage media filter.... I did not know the inner color of the media is Blue on the nanonet filter from all my reading. If I had read that just once in all those fuel filter threads then I would have know this was not the filter I was expecting to get, nor the filter I kept babbling on and on about.

Ram may in fact buy engines with out a warranty from Cummins. I am not sure if that is true or not, but I'll regress to your info as true till I find out otherwise. I do know that Ford bought Navastar Diesels and due to all the warranty claims from end users would file warranty claims to Navastar. Navastar got fed up with it, since they only sold the engine no electronics, and it was Fords "reprogramming" of the soft ware and electronics for the engines that pushed them out of their power design limits.... So the years and years of back and forth fighting is why they broke up. The same may or may not be true for the FCA/ Cummins joint venture.

speaking in terms of Wix filters. I run one in my ram but I think I'll be changing that when its time to something else.

I used to run all wix on my 60 series in my big truck. I switched everything but 1 filter to Detroit filters which are made by Donaldson to Detroit specs. I picked up throttle response, fuel mileage, oil pressure and overall performance. My family has run wix for 30+ years. I personally won't be going back to Wix.

Does anyone know who makes the filters for ram? is it fleetguard?

I don't know what the difference is on the filters you purchased, although I will be interested to hear any results, better fuel mileage, throttle response, so on.

Fleetguard makes the Mopar filters, and Cummins owns Fleetguard.

I lost 3 injectors in my 07 5.9 when I bought it new. All were covered under warranty and I had no problems from the dealer, which is the same dealer I went to this time when I bought this '12 (used). I attributed my injector issues to ULSD and poor filtering fuel filters. So I am super aware of fuel fill ups, mpg, and filter changes. I could tell when I had a injector failing as I would lose 2-3mpg, and the problem was the dealer would not replace it till it failed. When it did fail it sent the truck into limp mode, and always needed to be towed into the dealer. In fact that was the main reason I bought a Duramax. I have since come back to Cummins (another story). After a couple full tanks of fuel I should be able to report any mpg change with the Mopar filter compared to the WIX that was in it.... if any change at all. I have a insight now too, so I payed attention to Fuel rail pressure before the switch and should be able to see any change there too. Maybe a increase of fuel pressure with the smaller micron filter, but maybe not. Maybe it gets it's reading some place else.

I may pull this Mopar filter out, bag it in a zip lock, and keep it for winter use. My truck sits for days at a time, and the 5 micron rating vs. 3 micron rating will help guard against fuel gel causing filter issues.

Dealers want to dump the old part number. I had the same issue when I got mine and told them I want the nanonet not the old one.

Just look up a filter for a 2013+

Do you know the micro limits of the two stage Mopar filter they gave me? #68065608AA

I just see the 5 micron at 98.7%

I assume that means, at 98.7% capacity it is still filtering down to 5 microns. What I can't find is what each filter micron is. I assume the inner filter is the 5 micron, but then what is the outer.... 10, 12 micron?
No, that means that it filters out 98.7% of all particles 5 microns and larger. I honestly do not recall the overall rating on the outer filter on these. And I don't think that WIX filter even hits 5 micron...The Wix 33255 is only listed as a 12 micron filter according to their own site. 5 is barely ok, Bosch wants 2 micron absolute (100% @ 2 microns) for the CP3 - in practice a 2-3 micron filter works really well because we're actually pumping most of the fuel through the filter multiple times before the CP3 sucks on it.


But yeah, for a GOOD chunk of information, Cummins Fleetguard/Cummins Filtration - they're VERY clear about whats going on and they really are doing the research and testing.
