The more FFA an oil contains, the quicker it will break down and start smoking. [2] [3] The lower the value of FFA, the higher the smoke point. [4] However, the FFA content typically represents less than 1% of the total oil and consequently renders smoke point a poor indicator of the capacity of a fat or oil to withstand heat. [4] [5] [6]

The technical definitions vary between countries so the United Nations created the Globally Harmonized System of Classification and Labeling of Chemicals, which defines the flash point temperature of flammable liquids as between 0 and 140 °F (60 °C) and combustible liquids between 140 °F (60 °C) and 200 °F (93 °C).
Virgin olive oil is a lesser grade of virgin oil, with free acidity of up to 2.0%, and is judged to have a good taste, but may include some sensory defects. Refined olive oil is virgin oil that has been refined using charcoal and other chemical and physical filters, methods which do not alter the glyceridic structure. It has a free acidity ...
Another fun fact: Before lube hit the market, people often used Crisco, olive oil or Vaseline in its place, notes Wider. Though plenty of lubes are available now, Purdy says, it’s still possible ...
The autoignition temperature or self-ignition temperature, often called spontaneous ignition temperature or minimum ignition temperature (or shortly ignition temperature) and formerly also known as kindling point, of a substance is the lowest temperature at which it spontaneously ignites in a normal atmosphere without an external source of ignition, such as a flame or spark.

The flash point is the temperature at which oil vapors will ignite but are not produced in sufficient quantities to stay lit. The flash point generally occurs at about 275–330 °C (527–626 °F). [56] The fire point is the temperature at which hot oil produces sufficient vapors they will catch on fire and burn. [56]
