    A good spot would be under the kitchen sink where it won't get used accidentally and its greasiness won't be a problem for food packaging nearby.

    Why do you not pour used cooking oil out down the sink drain or in the yard?

    Because over time, oil poured into a sink can create a clog, especially when it is done repeatedly over time. It could also damage your soil and plants.
  • Question
    What is the shelf life of olive oil?
    Community Answer
    It can be as long as 3-4 years for an early harvest, high-polyphenol olive variety that has been filtered and packaged in a well-sealed tin or dark bottle, but that's not always the quality of olive oil you'll be using, so it's best to buy your olive oil in small quantities and use it within 6 months.

  • Question
    Is it safe to use cooking oil manufactured 3 years ago?
    Community Answer
    The answer to this question relies on several facts about the storage of/state the oil is in. For example, if the oil was stored in a cool, dry place in an unopened container, it may be okay for consumption. However, if bacteria has entered the container then the consequences could be disastrous. Since common cooking oils (like canola oil) are relatively cheap, it is always a better idea to start with fresh/newer oil than to try to reuse questionable oil.
