Who has owned Cummins / Fleetguard filtration?
I know their air filtration division is Nelson who Cummins bought because I remember doing business with "Nelson" before they changed.
What does Dodge use on their engines? You can't guarantee its a Fleetguard product...
I feel your engine's long life is a function of a better air filter more than a oil filter. Most engine oil filters are so loose that anything will work and its keeping the oil TBN and wear metals in line more so than the oil filter.
I think you'd better quit while you're (sort of) ahead here. You missed the point entirely on the cutaway photos of the Fram and NAPA filters.
Hint: Pleat count is somewhat critical to filtration capacity. Also, your blathering about Fram/Cummins etc is clearly a not so eloquent backpedal. I also use Fleetguard oil filters exclusively, Mopar air filters and Fleetguard and Racor fuel filters on my 2014 Ram. Racor incidentally, is the O.E. supplier for the rear frame mounted fuel filter.
"You missed the point entirely on the cutaway photos of the Fram and NAPA filters."
NO - I got it exactly right - there is substancial difference in the filters because the media area (IE pleat count) are differnet as well as the length. You need to compare 2 of the same filter in the same condition to make a real comparision. Who knows if the person making those pictures didn't rig the photos by distoring the end caps and moving the pleats over?
I applaud you for using the OEM filters.
You may not like the looks of the Fram filter, but it was doing its job and pleat distortion is a funcion of flow and media velocity and those were not too bad looking. The amount of media in that flter may be all that is needed for the application and they save consumer cost by designing the filter pack that way. End caps don't mean a thing if the media passes the integrity test in the end.
