WIX Fuel Filter.......

[kcpolk]

About 10k miles ago I replaced the fuel filter on my truck with a Wix 33255 (per the WIX listing). Looking at the WIX web site the other day…. I noticed it said 33255 is a 12 Micron filter. Uh oh….. Dodge/Cummins says use a 5 Micron or better. Damn! Called their customer service…. Closed. Ok…. I hit the dealer on the way home for an O.E. filter. I changed out the WIX that night. I haven’t had any problems with the fuel filter or my truck, but the Micron rating concerned me. I called WIX today…. They said that a Micron rating is not a good way to rate a filter. They believe what they measure as 12 Microns, could actually be rated as a 5 Micron by the O.E. test???? Anyway, WIX assured me that their filter is just as good or better than the factory filter and no harm has come to my truck by using their products. I like the WIX brand… I run their 57620XP Oil Filters and their air filters no problem. I have seen several Oil Filter cut-a-ways and the WIX is really constructed well in my opinion. However, when it comes to the fuel filter….. I think I will stick with the factory filter….. just to be sure. Anyone else have any experience or thoughts on this matter?

I highly advise you run the 3 micron filter. Gents garage sells them. About $62

FUEL FILTER - NANONET - MOPAR ('10 - '16, 6.7L) - 68157291

Not going to use (or even look at) the WIX fuel filter. Sticking with Cummins 12v98 recommendations above. But i did buy some wix oil filters. I run 2 oil filters (full flow & bypass) so i think WIX is good enough for that

The fit of the filter has been the same since 2010 however the filter was improved big time in 13. Wix is telling you there generic answer To make you go away. I have great faith in the 13-16 oem version and have installed one after my oem filter on my 05

I wouldn't touch any fuel filter that says WIX on it. I have yet to find one that filters as good as it's cross. Wix also won't tell you their f/w separation ratings... uh oh!!! Then again they are the company that asked me if I knew how small a micron was and if a few difference in microns was actually important!!

Wix is junk!

 

[Jonsnow]

I'm sticking with Mopar filters just for the micron difference and to cover my own butt. I use to use NAPA gold oil filters,(which are WIX) on my 99 Cummins but one day I was comparing them to the Mopar filter and noticed the NAPA had 6 drain back holes and the Mopar had 8 and they were larger. Now I use only Mopar filters on my 99 and 2014.

Mopar for me.. at the end if the day, wix won't back up there claim " no harm will be done" when you have to drop thousands of dollars to fix the fuel system.

On another forum, there was a thread 'Wix Mistake'. It was about an owner who had used wix fuel filters. It had allowed water past the filter, and enter the engine. All said & done, wix would not cover the cost for a replacement engine. IIRC, the total cost was around $25-$27,000.00. Marketing is a huge tool, and they will go to great lengths to say their item will work on your application. I use Mopar or Fleetguard fuel filters only. An ounce of prevention is always better than a pound of cure. The Wix fuel filters may be lower in cost, but if one fails, was the savings worth it??

Fleetgaurd or oem for me

 

[CGordon]

Fleetguard or Mopar only! The truck is far to big an investment to risk saving a few dollars on.

I only run Fleetguard filters on all my vehicles. They are usually less money than Mopar and, at least with oil filters, you get the choice of upgrading to the Stratapore filters. I am not going to "gamble" on an expensive engine by using cheap products.

On the subject of By Pass oil filters: As per Cummins:

Cummins neither recommends or encourages the use of by-pass oil filters on the B engine because improper use... can result in low oil pressure... If a customer insists on the use of a bypass lubrication filter, it MUST meet the following requirements:

A. Oil flow restricted to 1 GPM by using a 2mm orifice in the by-pass filter supply.
B. A check valve in the supply line which only allows flow to the by-pass filter when oil pressure is above 30 PSI.

I wonder what the purpose of the check valve is for, my return flow in my bypass is slow enough it would never affect oil pressure unless there was a catastrophic failure with the oil pump.

I recently got scolded by the local ALL Crane mechanic. Our 9130 with 8.3 Cummins started acting up during a critical shutdown and the mechanics were several hours away on another job. The mechanic had previously showed me how to access the codes through the diagnostic port and a low fuel pressure code was showing up. I made a few phone calls and all we were able to source was a Wix primary and secondary fuel filter, so that's what was used. We were able to get the crane back up and running and continued on with the job. About 4 hours later the mechanic showed up. Dang near had a seizure when he saw the Wix filters on his equipment :-laf. Changed em out on the spot with a set of Donaldson's and gave me an extra set to hold onto in case we ever need them.

The output on the amsoil is pinhole sized. That's what maintains the pressure and why oil return is relatively slow as JR says. Still in one hour of hwy driving, it will pretty much filter 10-12 quarts. Amsoil says it flows 1 gal per 7-10 minutes

 

[NIsaacs]

I have used Napa/Wix more than any other brand on all my equipment for the past 40 years.

All the ratings/advertising on almost all filters are misleading to the point of deception , The 2013 (10) + OE filters are the best you can buy. That 2 stage rotating filter that on the engine is marvelously designed.

Those spin-ons with steel tops no thanks, Geeze how many Injectors ports are plugged from rust flakes that brake off the top, Now you see why I don't support those spin-ons after factory canister. Before OK after NO.

 

[AH64ID]

Shadrach,

Were did you find that info? I recall reading it but I am not really certain where, but it might have been in the brochure/instructions for the Fleetguard spinner which requires a min of 30 psi to operate.

The amsoil bypass orifice is smaller than 2mm.

I have only ran without the bypass a couple time and never noticed a difference in oil pressure with my actual oil pressure gauge. I did, however, see an increase in oil pressure when I went to a ball bearing turbo that uses a lot less oil than the stock HE351.

 

[Cummins12V98]

FYI for those that don't know.

MOPAR air, fuel and oil filters are ALL made by FleetGuard for our 5.9 and 6.7 engines. FleetGuard is Cummins owned filtration company.

Look on genosgarage.com they sell both and sometimes the Mopar is less expensive than the FleetGuard. genosgarage is owned by the TurboDieselRegister, great people to do business with!

For the frame mounter fuel water separator on the newer trucks you can buy Raycor if it's less money and still have OE filtration as they make the Mopar filter.

 

[AH64ID]

IIRC there are 3 companies that MOPAR contracts to build their filters and Fleetguard is one of them.

 

[JR]

I just went back over my notes from when I made my bypass filter and I drilled my orifice to .042" which should be just a touch larger than 1mm. I copied the size that is used on the Amsoil bypass system.

 

[Cummins12V98]

Are you just saying Mopar in general or are you saying 3 companies building Cummins filters for Mopar?
