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.
