Based on some fairly sound oil analysis that I have seen, I would not go beyond 7500 miles or 1 year IF I were keeping the car for a long period of time, ie if I were liable for anything that happened to the engine.
If I were selling at warranty end, I would likely do the 15K.
Nice fiction, that 15K or 20 K oil change interval.
