How to tell if peanut oil(never used) is still good to use?

I have stored peanut oil(never used) in a cool place for the past 4 years. How do I know if it's still good? I don't want to purchase new oil if don't have to but I want my turkey to awesome!! Help!!! Thanks

Is there no use by date on it? I would not use oil after the useby date cos it will have gone rancid.
