I had previously had a problem with low oil pressure on startup, with a Fram filter. Consulted with various volvo forums to see if my oil pickup was dirty or if my oil pump was going bad, but they said that it was using low quality oil filters.
An oil filter should have a 1 way valve so that when you shut off your engine, your oil does not seep out of your lines and cause low oil pressure on startup which of course causes more wear on your engine. The fram filters I was using did not have those valves or at least had very poor iterations of a valve. My Volvo has made it to 300,000 miles and hopefully with these high quality filters it should last until a million.
I don't even think these are any more expensive than the store brands, and an ounce of prevention can save you a lot of money in engine repairs.
