This is your car, you can do whatever you want, but most people (like me) believe oil change between 5-6 k miles is highly desirable and for the peace of mind. The problem with long oil change interval is the oil filter will be saturated with all the dirt and debris and they may flow back into the engine. The way you maintain your car may hurt the re-sale value, but it is your car.
