It seems to me the mileage based oil change is the more sensible method rather than a time based change interval? I'm not knowledgable about the chemical properties of oils, either petroleum based or synthetic, but I wouldn't think the oil breaks down while sitting in the oil pan over time. It's the wear and tear on the oil while lubricating moving parts that is the primary factor.
