The size of an oil filter will not affect oil pressure, The oil pump, which is made up of enclosed gears driving the oil thru the engine passageways thru the bearings relys on bearing clearances to maintain oil pressure.

If the drainback valve has done it's job and kept the filter full, then there is NO effect on oil pressure. Actually your oil filter could be 5 gallon bucket sized! If the oil volume is sufficient, the engine oil system wouldn't know the difference.

Why?

Because "To the oil traveling thru the engine the filter presents itself as a larger passageway with more oil volume." ?

You're suggesting that a smaller volume filter; filters less? Hmmm.

If the filter and passageways are full then the size of the filter doesn't matter, only ''x'' number of ounces will be pushed by the pump anyway. Whether 8 oz are filtered thru 32 square inches of filter media or 8 oz are filtered thru 64 square inches of filter media- you still only have 8 oz of oil filtered. When I said setup scenario I meant the engine running an above average volume of oil, a larger filter would be right in line with this.....

The mopar would seem to be more about one size fits all; hence the bigger sizing?

I'm just banging on about this because i'm wondering if i really need a larger filter than the one i'm using and intend to continue using..
