If you're gonna do short trips, the synthetic will handle it better. This was proven in the SAE paper which described the Aunt Minnie test, where a car was driven for 5 years doing very short trips and all on the same batch of oil! In the beginning of the test it was 3 mile trips but then it was even less than this in the last half. I believe the oil went 7000 miles and they tore the engine down and found no significant wear.
