The flash point is the temperature at which vapor will ignite in a flame. The temperature where it ignites with no flame is the autoignition temperature. Liquids can vaporise at well below their boiling point, gasoline will vaporise readily at room temperature or below.

The vapor point of each gasoline will differ from others since the actual components in gasoline will differ. The gasoline vaporizes at the vapor temperature. If raised to the flash point, and oxygen is available, KABOOM.

They have different octane numbers. The higher grades of gas have more octane in them. That makes the gas less explosive under pressure. So you're able to use the gas in high compression engines(generally also high performance engines) with maximum effectiveness. It stops what's called "knock" when the gas detonates before it is supposed to. If you put it in a car that doesn't need it(or isn't tuned for it) then it could actually hamper that car since it will explode at the wrong time in that car also(too late instead of on time).
