Used cooking oil is a common byproduct of cooking, and it is important to understand its shelf life in order to ensure that it remains safe for consumption. The shelf life of used cooking oil can vary depending on a number of factors, including the type of oil used, how it is stored, and how it is used. Generally, used cooking oil can be stored for up to 1-3 months at room temperature, but this can be extended to 6-12 months if stored in the fridge. It is important to note that the shelf life of used cooking oil can be significantly reduced if it is exposed to heat, light, or air, as these factors can cause the oil to become rancid more quickly.
Proper storage techniques are essential for maximizing the shelf life of used cooking oil. It is important to store the oil in a cool, dark place, such as a pantry or cupboard, to protect it from heat and light. Additionally, it is important to ensure that the oil is stored in an airtight container to prevent exposure to air, which can cause the oil to spoil more quickly. By understanding the factors that can affect the shelf life of used cooking oil and taking steps to properly store it, you can ensure that your oil remains fresh and safe for use for as long as possible.
Proper Storage Techniques for Used Cooking Oil in the Fridge
Storing used cooking oil in the fridge is a great way to extend its shelf life and keep it fresh for longer. When storing used cooking oil in the fridge, it is important to transfer the oil to a clean, airtight container to prevent exposure to air and odors from other foods in the fridge.

Additionally, it is important to store the oil in the back of the fridge, where it is cooler and less likely to be exposed to light.
Another important consideration when storing used cooking oil in the fridge is to ensure that it is kept at a consistent temperature. Fluctuations in temperature can cause the oil to spoil more quickly, so it is important to avoid placing the oil near the door or in areas of the fridge that are prone to temperature changes.

Tips for Keeping Used Cooking Oil Fresh in the Fridge
In addition to proper storage techniques, there are a number of tips that can help to keep used cooking oil fresh in the fridge for as long as possible.

This can be done by pouring the oil through a fine mesh strainer or cheesecloth into the storage container. Additionally, it is important to avoid mixing different types of oils together when storing them in the fridge, as this can cause them to spoil more quickly.
It is also important to keep an eye on the color and smell of the oil when storing it in the fridge.
