Frying oil can be reused several times, but how long it stays good depends on a variety of factors, including the type of oil, how often it is used, and what is being fried. Oil can be reused anywhere from two to eight times. However, it is important to note that frying oil takes on the flavour of whatever it is used to fry, so it is best to keep oils used for savoury foods separate from those used for sweet foods.
To extend the life of frying oil, it should be strained and stored in a lidded container in a cool, dark place. It is also recommended to refrigerate stored oil. Oil should be allowed to cool completely before being strained and stored.
There are several signs that frying oil has gone bad and needs to be disposed of. These include the oil becoming dark or dirty, smoking before reaching frying temperature, foaming at the top, or developing a rancid or musty smell.

Oil can be reused until it starts smoking, turns dark, or adds nasty flavours to food
Oil can be reused several times, but it's important to know when to stop. There are several tell-tale signs that your oil has exceeded its lifespan and needs to be replaced.
The lifespan of frying oil depends on several factors, including the type of oil, how often it is used, and what is being fried. Frying oil can be reused anywhere from two to eight times. In a high-volume fast-food restaurant, oil may need to be changed every week or two, whereas a less busy home fryer may only need to change the oil every few months.
To extend the lifespan of your oil, it is recommended to use oils with a high smoke point, such as canola oil, sunflower oil, peanut oil, or avocado oil. Additionally, filtering the oil after each use and storing it in a closed container in a cool, dark place will help to prolong its usability.

Next, label the container. Include the date, what the oil was used for, and the number of times it has been used. Then, store it in a cool, dark place until you're ready to reuse it.
Oil takes on the flavour of whatever it's used to fry. So, if you've used oil to fry fish, it probably won't be good for frying sweet foods next. You can go in reverse, though—oil used to fry sweet foods can be used for savoury foods next time.
Frying oil can be reused anywhere from two to eight times. There's no hard and fast rule for when oil is no longer suitable for frying, so it's important to pay attention to your oil and detect any changes. If it's become dark or dirty, if it's smoking before it reaches frying temperature or foaming at the top, or if it's taken on a different smell (besides the food it's been used to fry), it's probably time to dispose of it.

Oil should be cooled completely before straining
Allowing oil to cool completely before straining is an important step in the process of reusing fryer oil. This is because fryer oil can be very hot, and straining it while it is still hot can be dangerous. It is best to let the oil cool down completely before attempting to handle it.
Once the oil has cooled, it is ready to be strained. This can be done using a cheesecloth set in a fine-mesh strainer, or simply by itself using a strainer. The oil should be strained into a clean container, such as a glass jar or the original container it came in. It is helpful to use a funnel during this process.
Storing the strained oil in a sealed container will help to extend its shelf life. It is recommended to label the container with the date, the type of oil, and the number of times it has been used. The oil should be stored in a cool, dark place until it is ready to be reused.
By following these steps, fryer oil can be reused multiple times, reducing waste and costs. However, it is important to monitor the oil for any signs of spoilage, such as a change in colour, smell, or texture, as this will indicate that it needs to be discarded.

Oil can be strained using a cheesecloth set in a fine mesh strainer
To strain oil using a cheesecloth set in a fine mesh strainer, first allow the oil to cool completely in the frying vessel after you're done frying. Once it's cooled, strain the oil through a cheesecloth set in a fine mesh strainer into a clean vessel, such as a glass jar or the container it came in. It is helpful to use a funnel for this process.
Straining oil in this way helps to extend the lifespan of the oil, and it can be reused several times before needing to be discarded. However, it's important to note that frying oil takes on the flavour of whatever it was originally used to fry, so it's best to keep this in mind for future frying projects. For example, oil used for frying fish probably won't be suitable for frying doughnuts next.
Additionally, the lifespan of frying oil depends on several factors, including the type of oil, how often it is used, and what is being fried. Oil can be stored in a sealed container in a cool, dark place for up to three months. Refrigerating the stored oil can also help to maximise its longevity.

Oil should be labelled with the date, what it was used for, and the number of times it has been used
Labelling oil with the date, what it was used for, and the number of times it has been used is a good practice to ensure the quality and safety of the oil for future use. Here are some reasons why this practice is beneficial:
- Oil Degradation Over Time: Oil can degrade over time, even when stored properly. Labelling the date when the oil was first used and the number of times it has been reused can help track its degradation. Oils have different shelf lives, and knowing how long it has been since the oil was purchased or first used can help determine if it is still safe to use.
- Type of Food Fried: Different types of food can impact the quality of oil differently. For example, frying breaded or fatty items can shorten the lifespan of oil compared to frying non-breaded vegetables. Labelling what the oil was used for can help you make informed decisions about reusing it for specific types of food.
- Oil Quality and Safety: Oil can go rancid due to various factors such as excess heat, exposure to sunlight, or age. Labelling the date and use of the oil can help identify if it has exceeded its recommended shelf life. Additionally, used oil may develop off-flavours, a foul odour, or a darker colour, indicating that it needs to be replaced.
- Maximizing Oil Usage: By labelling the number of times the oil has been used, you can better determine when it is time to replace it. This is especially useful if you are frying different types of food that have varying impacts on oil lifespan. For example, oil used for frying non-breaded vegetables can typically be reused 6-8 times before replacement, while oil used for breaded items or fatty meats may need to be replaced after 2-4 uses.
- Consistency in Food Quality: Using oil that is within its recommended lifespan and suitable for the type of food being fried can help maintain consistent food quality. This is especially important in restaurants or commercial settings, where the quality of fried items can directly impact customer satisfaction and the reputation of the establishment.

Frequently asked questions
Frying oil can be reused anywhere from two times to up to eight times. It depends on the type of oil, what you're frying, how well you've strained it, and more. There's no hard and fast rule for when oil is no longer suitable for frying; instead, pay attention to your oil and detect any changes. If it's become dark or dirty, if it's smoking before it reaches frying temperature or foaming at the top, or if it's taken on a different smell (besides whatever foods you've fried in it) that is rancid or musty, then it's probably time to dispose of it.
To extend the life of your fryer oil, you should filter it after each use. You can use a sieve, a coffee filter, or even a silica hydrogel like Britesorb C935 to remove particulates, free fatty acids, and soaps. You should also store your oil in a cold, dark, airtight place.
Do not pour fryer oil down your sink drain. You can solidify it and then throw it in the trash, transfer it to a closed container and then toss it, or recycle it.
