6.7L Cummins Air Filter Revision...53034051AB is now 68517554AA

I'm surprised you don't change on hours vs miles considering your usage.

Someone at RAM is more educated in air filtering than I am, so I go by the 30k maximum interval as spelled out in the diesel supplement.

Keep in mind.........White Lightning is really going through a LOT of air in 30k miles.....with a lifetime average mpg of 10.15 mpg.

 

[JR]

What you do obviously works well so there's no argument there from me. Their service intervals also have to cover a wide range of driving conditions. My avg mpg is not all that far off from you, but to achieve the same 30k miles my engine hrs are without a doubt substantially higher than yours. Lots of lower speed towing and very few highway miles.

Saturday, at 363,224 miles, 917 idle hours, and 6,349 drive hours, White Lightning received:

• 3 gallons of 5W40 Delo 400 XSP synthetic
• DBL 7349 oil filter
• Fleetguard FS 53000 underhood fuel filter
• MoPar 68197867AB rear separator
• New fangled MoPar 68517554AA air filter
• greased the front drive shaft
• greased all front end parts
• replaced two LED CM SK bed lights
• checked and set tire pressure
• installed some new Diode Dynamics DD6679 White fog lights

The revised air filter will get a workout bright and early Monday morning.

We will see how it does soooon!

I just ordered some fuel, oil, and air filters from Genos, and I was able to get the Fleetguard air filters that I like. Hope I actually get the Fleetguard. I hope have to settle on Mopar fuel filters however.

 

[bcbender]

I have three of the old style on my shelf, so at 30K mile change intervals, I may never have to buy another air filter

I also have 2 of the older style on the shelf so by the time I need to buy one, the supply chain should be corrected?

 

[Tuesdak]

I just opened my Genos package and the Fleetguard air filter is the old style yellow media and all. Looks like the Wix air filter is identical to the Fleetguard visually. Only the printed name on the filter can you tell them apart.

 

[gsbrockman]

White Lightning is currently at 403,342 miles, 1,017 idle hours, and 7,047 drive hours.

It received an oil change with a DBL7349 oil filter, three gallons of Rotella T6 5W40 synthetic, Fleetguard under hood fuel filter, MoPar rear separator, and I also greased the front end parts and front driveshaft.

I‘ve been running really hard the last few months. This last oil change lasted 13,847 miles and 35 days and 241 drive hours.

GS have you ever done a oil analysis on WL? Curious if it would say you could run longer especially with the type of use it gets.

 

[JR]

Ram should break into the 21st century and use an oil algorithm like every other manufacturer has used for a decade or longer. It would be very beneficial to guys like Greg who max out on miles well before they do on hours, or vice versa.

For this they would need an oil temp and oil pressure sender - what Cummins avoid like the plague to put on our engines.

I believe GM has a separate sensor just for oil quality. What it measures I am not sure.

Maybe Ram/Cummins just know that oil life isn’t a big deal on these motors? At a minimum it should give you a scale based on all 3 parameters, hours/miles/age.

I do believe it will shorten the life based on fuel dilution thou, but that’s not really an issue since 2013.

 

[gsbrockman]

GS have you ever done a oil analysis on WL? Curious if it would say you could run longer especially with the type of use it gets.

I’ve not performed any analysis on WL to date. You do bring up a valid point, though....

Based on RAM’s 15,000 mile, 500 hour, six month rule......I figure I’m safe, although regular analysis couldn’t hurt. My truck is bone stock....so it can’t hurt itself.

 

[AH64ID]

@gsbrockman you could likely run 500 hours on a OCI, which would approach 25-30K miles. Not sure how many idle hours you had last OCI but your moving average was 57 mph.

 

[JR]

Ford looks at fuel consumption (gallons used), ambient temps, idle time, and avg speed off the top of my head for their algorithm.
Our Explorer doesn't have a real oil pressure sensor either but I'm not sure what they have on the Super Duty.
In the case of our Explorer the oil change light could go off anywhere between 5k miles (extreme driving) up to 12k miles (mostly highway, minimum idling)

 

[AH64ID]

My brother thinks his ‘17 F-250 Powerstroke also has a way of knowing air intake quality. He always feels his OCI is shorter when he does a bunch of dusty driving, but maybe it’s just the hours/avg speed.

 

[Tuesdak]

I believe GM has a separate sensor just for oil quality. What it measures I am not sure.

No sensor. (The low oil level sensor doesn't count.) GM's software is biased on engine revolutions and other factors subtract from it. Like extreme heat, cold short trips, etc. Towing with higher average temps that oxidize the oil... It has a maximum mileage that will trip the oil change light. You get to make sure it doesn't go over 1 year. Other than the "timing chain disaster" where GM had to cover it up by revising the OCI in the software it's pretty accurate. We were doing 5000 mile oil changes on the GM pickups in the fleet and when the 1999's came out with the OCI system the light would be tripping around 5000 miles. The 2008 Duramax of ours would trip just under 10,000 miles and come to find out this was the mileage limit in the ECM. Oil samples verified the system worked esp. the changes that tripped "early".

The system won't figure out you are using B99, lost viscosity because of B99, coolant leaks, or the air filter "imploded" and you got a lot of dirt in the oil ... That 2008 air filter was quickly redesigned to put a plastic "X" looking stop in it to support the element. Later manuals also have a mileage limit for said air filter set at 50K. The failed one below was removed at 57K miles and less than one year old. Wonder why the restriction gauge never showed anything.

The center element was "loose"...

Fram CA10261 is less than $20 at WalMart or the Zon and claims to serve all years of 6.7L Cummins Rams. It looks identical and claims to be exact replacement for the Cummins/Fleetguard AF37684.. Is it only Ram with Cummins that are so picky about what specific air filter is acceptable???

I wish I had a nickel for every time I've hear that with products, services, etc...

Fram ok for some things, but I only use OEM filters or technically proven replacements with superior qualities (ie Fleetgaurd, Donaldson, Racor).. I personally would not risk the 10k engine with trying to save a buck there.

Do you wish to replace the air filter every single year? FRAM say to replace their air filters every year on their website.

Also as an update: Wix has gone to their own "Not Fit For A Purpose" design that experiences media being sucked in as the "re-imagined" plastic mesh ain't up to the task. There is a 1/4" gap between the media and sucked in plastic in the photos below.

I believe that to be a blanket statement. I have seen this recommendation from vehicle manufacturers as of late.

On the subject of air filters. Here is some real bean counter engineering. Hauling a load of stone, 27k Gross, coming up a hill and under boost and I get a DING! Service air filter message. Hmm.
Turns out it wasn't the air filter but the cheesy cardboard tube Fiatsler chose to run in the passenger side fender well. I'm not certain of the exact sequence but the obvious is it collapsed and sucked itself into the dang air box. And the good part, it broke the clamp on the inlet of the turbo due to the engine suddenly being starved of O2 and trying to suck itself inside out. Inside of the clamp was rusted to hell and brittle but you'd never know it by looking at the outside of the clamp as installed.
