How to Store Oil

All of the oil remains liquid when kept at room temperature so it is best to store oil in a cool, dark and dry place, such as your pantry. While different oils have different store methods.
Oils that are high with monounsaturated fat will keep up to a year, while refined olive oil, which has the highest of monounsaturated fat, can last a few years. Extra virgin and virgin olive oils will keep about a year after opened. The shelf life of most other oils after opened is usually six-eight months. Do not store oil in that pretty jar in the kitchen window or keep it on the shelf next to the stove.
One important reason to store oil is keep it from oxygen. The only measure you can take is storing oil in jars and then using a food saver device to extract oxygen from the jar. Even that isn't fool-proof.
