can used cooking oil go bad?

Oxidation can occur when the oil is exposed to heat, light, or air, so it’s important to store used cooking oil properly to prevent this from happening. If you’re not sure whether your used cooking oil has gone bad, there are a few things you can check. First, take a look at the oil. If it has changed color, become cloudy, or has a strange odor, it’s best to discard it. You can also taste the oil. If it tastes rancid or bitter, it’s definitely gone bad and should be thrown away. Finally, you can check the smoke point of the oil. If the oil smokes when you heat it, it’s a sign that it’s too old and should be replaced.
how long can you keep used cooking oil?
Used cooking oil can be kept for various durations depending on the storage conditions and the type of oil. If stored properly, most cooking oils can last for several months or even longer.

what is the healthiest oil for deep frying?
