Who makes the MOPAR filter is a toss up, might even be a Fram for all anyone knows
we do know that the oil at the dealership is a Shell oil product, PENNZOIL
All the ones Ive looked at appear to be built by Purolator and have a similar thread end bypass as the FL820S Motorcraft (That also fits our trucks). However they are not the same and dont even share many parts. The base plate for instance is a completely different design.
The oil in both bulk (assuming the dealer participates in the Mopar Oil Purchase Program) and bottle form is "Shell's Premium Conventional" aka Pennzoil Yellow Bottle.
