API Standards Committees are made up of subcommittees and task groups that works and maintain these standards. [10] [11] API also defines the industry standard for the energy conservation of motor oil. As of 2020 API SP is the latest specification. It supersedes API SN. SP specifies more stringent engine oil performance requirements for spark ...
Crude oil is classified as light, medium, or heavy according to its measured API gravity. Light crude oil has an API gravity higher than 31.1° (i.e., less than 870 kg/m 3) Medium oil has an API gravity between 22.3 and 31.1° (i.e., 870 to 920 kg/m 3) Heavy crude oil has an API gravity below 22.3° (i.e., 920 to 1000 kg/m 3)

West Texas Intermediate (light blue) alongside other selected North American oil benchmarks. West Texas Intermediate is used primarily in the U.S. It is light (API gravity) and sweet (low-sulfur) thus making it ideal for producing products like low-sulfur gasoline and low-sulfur diesel. Brent is not as light or as sweet as WTI but it is still a ...
The clear cut definition of light and heavy crude varies because the classification is based more on practical grounds than theoretical. The New York Mercantile Exchange (NYMEX) defines light crude oil for domestic U.S. oil as having an API gravity between 37° API (840 kg/m 3) and 42° API (816 kg/m 3), while it defines light crude oil for non-U.S. oil as being between 32° API (865 kg/m 3 ...
Engine oil which has been tested and meets the API standards may display the API Service Symbol (also known as the "Donut") with the service categories on containers sold to oil users. [21] The latest API service category is API SP for gasoline automobile and light-truck engines. [22] The SP standard refers to a group of laboratory and engine ...
An API well number or API number is a "unique, permanent, numeric identifier" assigned to each well drilled for oil and gas in the United States. [1] The API number is one of many industry standards established by the American Petroleum Institute. Custody of the API Number standard was transferred in 2010 to the PPDM Association.
API TC is a certification for two-stroke oils, awarded by the American Petroleum Institute. It is given after the product passes through stringent tests that determine the level of detergent performance, dispersion, and anti-oxidation. It is the only remaining, not revoked classification of the API Two-Cycle motor oil specifications (TA, TB, TC ...
