Autoignition temperature is another name for ignition temperature. This is defined as the lowest temperature needed for the oil to combust without flames or sparks.
A flash point of a liquid is the minimum temperature needed for a flammable mixture to be created in the surrounding air. The flash point of oil can vary by oil type, but the average is 600 degrees Fahrenheit.
If the oil is smoking or boiling, it is an indication that the oil is close to igniting and poses a fire risk.Learn more about Cooking
