Store the oil to be reused in cooking or deep frying for no longer than three months and avoid re-using the oil for deep frying more than once or twice, as the smoke point of used oil is reduced after multiple uses. Avoid pouring your used deep fryer oil down the drain or tossing it in the trash.
Refrigeration does not affect the quality or flavor of other olive oils. Olive oil will keep well if stored in a sealed container in a cool, dark cupboard for about one year. If unopened, the oil may keep for as long as two years. Unlike wine, oil does not improve with age.
