I found my oil pressure raised 20 psi with my last Mobil 1 filter....
That suggests less flow.... so I went back to AC/Delco
What were/are your oil pressures with the Mobil 1 and AC/Delco filters? I use the Mobil 1 filter and at operating temp get low 30s psi at idle and mid 40s psi at highway speed. I don't consider those pressures to be overly flow restrictive.

Puzzled about this one...the new Mobil 1 filters are supposed to have better flow with excellent filtration and don't have the K&N nut that extends below the car that risks contact with something in the road.
