How many miles on the paper filter, what oil are you using?
For many miles I took my truck to the dealer who installed
the Mopar paper filter. My oil pressure was just like yours,
but what disturbed me the most was the coal-black color of
the oil shortly after a change.
Judging by the bad feeling I was getting from my dealer after
reading through the receipts and seeing zero consistency in
the oil they were using, sometimes synthetic, sometimes no
mention, sometimes 5w-20, once they wrote 5w-30.
While I was told they used only Pennzoil synthetic, 90% of
my receipts just said "oil".
I switched to Pennzoil Ultra Platinum (PUP) 5w-20 and Royal
Purple oversize 20-820 filter, saw the same oil pressures but
the oil began to look newer longer.
Currently using Red Line 5w-30. Now that increased the oil
pressure. I have to be running it pretty hard and hot to see
pressures in the high 30's. Mostly it now runs from 40psi to
60-65 psi.
Most of all my oil is looking progressively cleaner for longer
periods with each change.
Looking back in time I can't help but wonder if those paper
filters were simply clogging up and going into bypass, leading
to the black oil. And I mean solid black at 500 miles.
I'm betting you new filter is allowing greater flow as well as
greater filtration. Might need to change something else to see
a change in pressure, but IMHO 35psi at hot idle is pretty
normal.
