How long does it take for oil to burn off?

The time it takes for oil to burn off can vary widely depending on factors such as the type of oil, the temperature of the fire, and the amount of oil present. In a typical scenario, small amounts of oil can burn off in a matter of minutes, while larger spills or thicker layers of oil may take hours or even days to fully combust. Additionally, environmental conditions like wind and humidity can influence the burning process.
