How often should you dispose of fryer oil?

Over time, fryer oil can degrade and become less effective for frying. How often you should discard the oil will depend on several factors, including the type of food you're frying and the volume of oil you're using. One indication that it's time to discard the oil is if it smokes at lower temperatures than before. Additionally, if the oil has turned darker in color, has an unpleasant odor, or has a thick, foamy surface, it's likely time to discard it. Properly disposing of used fryer oil not only ensures the flavor and quality of your fried foods, but also helps maintain the longevity of your fryer.
