After about 6k miles I noticed my oil pressure would hold at about 22 PSI. I'm too busy to change the oil so I rolled with it until I changed the oil and about a week ago (1/29) and the oil pressure has been holding steady at 38-40 PSI. What is going on here? Why did I lose oil pressure after only 6k miles? I drive 130 miles roundtrip to work 7 days every two weeks. I'll try to post photos of the filter cut open as soon as I bring my cutter home from the hangar.
