It is recommended to use air tight container for storing oil for long time.
Answer:
It is recommended to use air tight container for storing oil for long time because:

⇒ This can make the oil rancid (a foul smell).
⇒ Thus, it is advised to use air tight container for storing oil to prevent it from exposure of air.
