Oil analysis tells me that the good oil I use along with a decent store bought filter is still doing ok at 6000 miles and that's good enough for me. That saves me plenty of oil changes with the fleet that satisfies me, with a couple cars well over 200k miles like that and still running fine. They owe me nothing.
