What Are Two Ways to Increase a Fuel's Octane Rating?

Answer

The octane rating of gasoline tells you how much the fuel can be compressed before it spontaneously ignites. During WWI, it was discovered that you can add a chemical called tetraethyl lead (TEL) to gasoline and significantly improve its octane rating. In addtition, mothballs increase fuel octane and were used during World War II. Naphthalene was the active ingredient in mothballs and octane ratings of gasoline were 60 to 80.
