Hmmm. A range of different answers. See I believe that synthetics are better and maintain their chemical properties longer than conventional, but I dont think filters are meant to do their job for as long as some of these synthetics are supposed to last. I've read several different articles on synthetic lab testing but nothing on filters. I hear the motorcraft one that came from the factory is the best one. I agree changing oil regulary is cheap insurance to keep the motor in tip top shape but I dont see the point in spending money on an oil change if the filter and oil are perfectly fine. Does the oil life monitor actually read the life through a sensor or calculate based on miles and driving style? It sounds like based on what I've heard, Ill just stick with ford recommended oil and filters every 5k.
