Not so.

More restriction through the filter INCREASES oil pressure (with no other changes). To support this claim I offer you two examples:

Power steering system - there is a built in check-valve to provide restriction, without it the pressure is not there. My car validated this when the check valve went south I lost power assist.

High blood pressure - caused by restricted arteries (mainly). Have not had personal experience yet.

This is one of those thing that goes against "conventional wisdom".

So it seems I'm switching to Bosch.
