It is defined as the equilibrium partial pressure exerted by a volatile organic liquid as a function of temperature as determined by the test method ASTM D 2879. [ 1 ] The true vapor pressure (TVP) at 100 °F differs slightly from the Reid vapor pressure (RVP) (per definition also at 100 °F), as it excludes dissolved fixed gases such as air.
Reid vapor pressure (RVP) is a common measure of the volatility of gasoline and other petroleum products. [1] It is defined as the absolute vapor pressure exerted by the vapor of the liquid and any dissolved gases/moisture at 37.8 °C (100 °F) as determined by the test method ASTM-D-323, which was first developed in 1930 [2] and has been revised several times (the latest version is ASTM D323 ...
The oil crises prompted the first shift towards energy-saving (in particular, fossil fuel-saving) technologies. [5] The major industrial centers of the world were forced to contend with escalating issues related to petroleum supply. Western countries relied on the resources of countries in the Middle East and other parts of the world.
In addition to high oil prices, from year 2000 volatility in the price of oil has increased notably and this volatility has been suggested to be a factor in the financial crisis which began in 2008. [63] The perceived increase in oil price differs internationally according to currency market fluctuations and the purchasing power of currencies.
The higher the gasoline volatility (the higher the RVP), the easier it is to evaporate. The conversion between the two fuels occurs twice a year, once in autumn (winter mix) and the other in spring (summer mix). The winter blended fuel has a higher RVP because the fuel must be able to evaporate at a low temperature for the engine to run normally.

The international dependence of energy resources exposes countries to vulnerability in every aspect of life — countries rely on energy for food, infrastructure, security, transportation, and more. In the Scottish Independence debate, energy independence is a key argument in favour of Scottish exit.
