The day I switched from paper filters to synthetic and saw my oil pressure jump 8 psi
I was working on a 2012 Cummins ISX last Tuesday for a local fleet guy out of Tulsa. Old engine, but it had a weird low oil pressure reading at idle that just bugged me. I pulled the factory paper oil filter and swapped in a Wix synthetic filter (XP series) I had on the truck. Literally fired it back up and the gauge read 8 psi higher at hot idle, from 22 to 30. The paper filter was collapsing a bit under pressure, restricting flow. Took me 20 minutes total and the guy thought I was some kind of wizard. Has anyone else seen a big swing just from the filter media change?

Paper filters choking is real, my old Ford did the exact same thing.

You ever seen a car just give up halfway up a hill? My buddy's truck did that with a paper filter, sputtered and died right at a stoplight. He switched to a reusable one after that and never looked back.
