Volatility
Good drivability is determined by volatility, or the measure of how gasoline changes from a liquid to a vapor. How your engine starts up, idles and runs defines the driveability of your car. A lot of external factors influence volatility — and, in turn, driveability. Chief among them are altitude and seasonal temperature.
To improve volatility, different blends of gasoline are created. In cold weather, we blend it to vaporize easily, enabling your engine to start quickly and run smoothly. In warm weather, we want the opposite. Gasoline is blended to vaporize less easily, preventing vapor lock and other hot-fuel handling problems.
