On cars that I've used non-synthetic I always change the oil at 3-4k, maybe 5k max for cars like my mom's that don't get driven hard at all. On my Turbo I run synthetic with a quality filter and change both every 5k, that's how you get 250-300k out of an engine. Manufacture recommendations will get you through the warranty, then it's about shot.
