I am a frugal kind of guy, and I hate to waste money--but I am going to say that you need to change it. Its not that the oil is "bad," it just becomes diluted, usually by water formed by condensation when a combustion engine is not run at full operating temperature long enough to boil it out of the oil. I imagine this is probably the case in your circumstance with so little annual mileage on the car. The water can cause the oil to lose its effectiveness as a lubricant as well as render the additive package worthless.
