You can read and read and research and research oil until the cows come home and the bottom line is, if you use the correct grade oil and change it like recommended for your situation your car will run probably longer than you're going to want to drive it. Brand really doesn't matter as long as it meets the mfg's requirements. Filter? As long as it's changed as required, what brand probably doesn't matter there either.
