I know since you have read this article so far, the obvious question you would like an answer to is, "How long can you retain oil in a deep fryer?" Without any further ado, let me get this clear for you. Based on how much oil you use in the fryer, the prescribed range for storing it in a deep fryer would be a few days or a few weeks. As such, up to three months after the date of original use, used oil can be stored and still be ideally suited for use.

However, keep in mind that it is only applicable if precaution has been put in place to guarantee that you keep the oil in a cool, dark area (perhaps in a fridge) or frozen. It is the suggested period during which it is edible. In particular, anything slipping outside of this timespan may be called dangerous.

For deep frying clean vegetables, use the oil around six to eight times before changing it. On the other hand, for fatty meats, fish, or breaded items, use the oil two or three times. There is also no one-size-fits-all solution to understanding when to replace the oil in a deep fryer.

Before you need to change the frying oil, ask yourself:

How often do you use it? (daily, weekly)
Do you fry bready items? (it leaves a lot of debris in the oil)
Which type of oil do you use? (refined peanut or vegetable oils last more)

What do you fry in it? (potatoes will affect it differently than fish)

I would recommend you retain oil in a deep fryer for up to three months. Let the device and oil cool for two hours after preparation. Then drain the oil through a strainer or cheesecloth into a bowl. Place a lid on the jar for the optimal output, then refrigerate. There are certain precautions that you may want to take before determining when to change your oil.

Signs to Watch for in Oil that Requires to be Changed

Here are some situations where you might have to change the oil in the deep fryer as soon as possible. I have listed all the possible scenarios I could imagine. If you notice any of these, throw the existing oil and use fresh oil for your next batch of snacks.

The oil is hot, and you see foam on the surface.
Too much smoke from the oil.

You get the smell of fish even though you do not fry fish.
The oil is too dark in color compared to the original.

In conclusion, a smart way to conserve both time and resources is to reuse the cooking oil. If you use the oil many times, you can get more uses per bottle of oil you buy. It saves you time by not having to go as much to the supermarket. If you reserve oil in the deep fryer at the start of cooking, you can directly start frying.
