How often can I use cooking oil
The number of times you use the same cooking oil depends on the type of food you are preparing. When frying breaded or battered foods, a lot of debris will accumulate in the oil. When this debris is heated up several times, it may affect the quality of the oil. Reuse the oil a maximum of 3 or 4 times and make sure to clean the oil as much as possible before heating it up again. For other items like potato chips, the oil can be reused 8 times.
