Mobil 1 is better than any dino oil, however if you're going to change your oil every 2 or 3k there is no need to go with a synthetic really. If you go with Mobil 1, to get your money's worth out of it's higher cost, go to at least a 5 or 6k oil change interval, or more. This oil can handle that interval with ease.
I change every 3K, however. These oils turn black faster than conventional oils but they last longer.
