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.
