Cooking oil, whether it’s vegetable oil, olive oil, coconut oil, or any other type, has a shelf life. The shelf life of cooking oil varies depending on the type of oil and how it is stored. Generally, most cooking oils have a shelf life of one to two years when stored in a cool, dark place away from heat and light.
