Deep Frying: How Long Can Oil Last?

Oil can be kept in a deep fryer for up to six months, but it's recommended that it's changed after eight to ten uses. However, some people change their oil after five or six uses, or even after two to four uses. It's important to strain or filter the oil after each use and store it in a cool, dark place.

Oil should be changed after 6-10 uses

Some people may consider reusing the oil for much longer as an economical option. However, this can be harmful to health and cause diseases. It is also important to note that even though the oil may be strained and cooled in the fridge, it will still contain some of the cooked substance, and recooking stuff over and over is not healthy.

One user says they keep the oil in the fryer and take it out to filter it after it's cool. They use the fryer once a month and change the oil a couple of times a year. Another user says they use their oil about ten times and never take it out of the deep fryer. It usually sits between uses for about 2-3 weeks and is always ok. They let it cool down, then put the lid on the pan and cool it overnight. They then pour it through a fine mesh sieve into a large mason jar, seal it and put it in an upper cabinet. It is in the dark most of the time and away from heat, and this seems to work out fine for them.

Oil should be strained or filtered after use

Some people choose to keep the oil in the fryer and take it out to filter it after it has cooled. However, it is recommended that the oil is removed from the deep fryer after each use.

Oil should be stored in a cool, dark place

To store oil correctly, you should remove it from the deep fryer after each use, strain it, and store it in a cool, dark place until the next time. This could be in a washed and dried one-litre pop bottle, or a large mason jar. It is important to note that even strained and cooled oil will still contain some of the cooked substance, and recooking this is not healthy.

Oil should be stored in a sealed container

To store oil correctly, pour the strained oil into a one-litre pop bottle that has been well washed and dried. Keep the filtered oil in a cool, dark place until the next use. Food residue left in the oil will give it a bad taste, so it is important to keep it away from heat, not over the stove or oven.

Some people choose to keep the oil in the deep fryer and take it out to filter it after it has cooled. This is not recommended as the oil will still contain some of the cooked substance, and recooking stuff over and over is not healthy.

Oil should be discarded after six months

Oil should be removed from the deep fryer after each use, strained, and stored correctly until the next time. It's important to keep the filtered oil in a cool, dark place, as food residue left in the oil will give it a bad taste. To do this, pour the strained oil into a well-washed and dried one-litre pop bottle.

Some people keep the oil in the fryer and take it out to filter it after it has cooled down. This method doesn't appear to do any damage, but it's important to note that even strained and cooled oil will still contain some of the cooked substance, which is not healthy.

It's also worth considering the rising cooking oil prices. While it may be tempting to reuse oil to save money, consuming rancid oil can lead to health issues that will cost more to treat in the long run.
