Gasoline can be ignited by even a tiny spark at temperatures as low as fifty below zero, but it merely evaporates at temperatures up to about four hundred seventy five to five hundred F. At that temperature, it ignites spontaneously.
That is what you ignite if you were to try to light hot cooking oil in the pan. The smoke point for olive oil is about 193 C. The ignition point (called the flash point) is higher than the smoke point. You have to get enough organic vapor into the air to sustain combustion. For olive oil This is around 225 C (437 F).
