What is the main use of red vapor pressure?

I checked, and it relates to volatility, but what is the main purpose of this indicator?
One of the methods for expressing gasoline volatility. Volatility is an important property of automotive gasoline. If volatility is too high, too much oil vapor will be generated during high-temperature operation, resulting in a loss of engine power, unstable operation, or even shutdown; this phenomenon is known as \"air lock\". On the other hand, it increases evaporation losses, leading to the contamination of the atmospheric environment by volatile organic compounds (VOC) and hydrocarbons (HC). If volatility is too low, insufficient fuel evaporation will result in difficulty starting the engine when it is cold.
