Does motor oil go bad from sitting?

Motor oil can only last for a certain period of time. That's why it comes with an expiry date. For this reason, oil goes bad with time just by sitting in the engine. Over time, it becomes less viscous thus less efficient in maintaining proper lubrication between moving components.

What color should synthetic oil be?

Is it worth it to get synthetic oil?
