For instance, viscosity, wax content, sulfur, and acidity are important to crude oil transportation and refining, while API Gravity is important for crude oil trading and pricing. What Is API Gravity? API Gravity is a measure of how heavy or light crude-oil is compared to water (density of crude oil / density of water). Both a crude oil's viscosity and its API (American Petroleum Institute) degree are important parameters for classification. Crude oil's viscosity can vary from a low-viscosity liquid to up to tar-like, nearly solid form. Classification according to the API degree: Light crude oil: API gravity higher than 31.1 °API (less than 870 kg/m³) The API of crude oils varies typically between 10 and 50, with most crude oils falling in the range of 20-45. Using API gravity, the conventional crude oils can be generally considered as light (°API>30), medium (30>°API>22), and heavy (°API<22). Note that the relationship between °API and specific gravity is not linear. American Petroleum Institute (API) gravity is the measure of the weight of crude oil. API gravity is a measure of the weight of a crude oil in relation to water. “If an oil’s API Gravity is greater than 10, it is lighter than water and will float on it. If an oil’s API Gravity is less than 10, it is heavier than water and will sink.” API gravity and viscosity API (American Petroleum Institute) gravity is a standard parameter that determines the transportability of crude oil via pipelines G Model APCATB-15168; No. of Pages 13

Heavy crude oil is highly-viscous oil that cannot easily flow to production wells under normal reservoir conditions. It is referred to as "heavy" because its density or specific gravity is higher than that of light crude oil. Heavy crude oil has been defined as any liquid petroleum with an API gravity of heavy crude oil present special challenges compared to light crude oil.
