Api crude oil grades explained

The American Petroleum Institute (API) is the only national trade association that represents all aspects of America’s oil and natural gas industry. Our more than 600 corporate members, from the largest major oil company to the smallest of independents, come from all segments of the industry. API FA-4 oils are designed to provide enhanced protection against oil oxidation, viscosity loss due to shear, and oil aeration as well as protection against catalyst poisoning, particulate filter blocking, engine wear, piston deposits, degradation of low- and high-temperature properties, and soot-related viscosity increase. API FA-4 oils are not interchangeable or backward compatible with API CK-4, CJ-4, CI-4 with CI-4 PLUS, CI-4, and CH-4 oils. Refer to engine manufacturer recommendations

Light Crude Oils Light crude oils have a high API gravity >35, they will produce more of the value products such as gasoline, kerosene and diesel. Examples: Asgard Condensate, Copper Basin, Kerapu. The term “API Gravity” refers to the “American Petroleum Institute Gravity, which is a measure that compares how light or heavy a crude oil is in relation to water. If an oils “API Gravity” is The service rating of passenger car and commercial automotive motor oils is classified by the American Petroleum Institute (API). The program certifies that an oil meets certain Original Equipment Manufacturer (OEM) quality and performance standards. The service rating is shown in the API "Service Symbol Donut" on the product label.

API FA-4 oils are not interchangeable or backward compatible with API CK-4, CJ-4, CI-4 with CI-4 PLUS, CI-4, and CH-4 oils. Refer to engine manufacturer recommendations Crude oil is considered "heavy" if it has long hydrocarbon chains, or "light" if it has short hydrocarbon chains: an API gravity of 34 or higher is "light", between 31-33 is "medium", and 30 or below is "heavy". Classifications or grades 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). Extra heavy oil has an API Crude oil is classified into various grades according to density (heavy vs light) and sulphur content (sour vs sweet). The lighter and sweeter the crude, the higher the price it can be sold, because refiners can produce higher yield of high quality refined products from it. Density is measured by API gravity,

Refer to engine manufacturer recommendations Crude oils that are light (higher degrees of API gravity, or lower density) and sweet (low sulfur content) are usually priced higher than heavy, sour crude oils. This is partly because gasoline and diesel fuel, which typically sell at a significant premium to residual fuel oil and other "bottom of the barrel" products, can usually be more easily and cheaply produced using light, sweet crude oil. The light sweet grades are desirable because they can be processed with far less sophisticated

Crude grades Crude oil comes in hundreds of different varieties or "grades." These grades are valued differently by refiners based on their crude qualities .

The first three groups are refined from petroleum crude oil. The first three groups are refined from petroleum crude oil. Old motor oil and even some newer blends (when used in older engines) can cause harm to your engine. That's why it's important to understand API ratings. What are API ratings, how are they Motor oil or engine oil is also rated on how well it holds up under severe service conditions in the engine. The API service rating is an oil rating system that specifies how well an oil performs under severe engine service. The American Petroleum Institute (API) service ratings are related to automobile warranty standards. The small engine maker determines which of the ratings are acceptable to meet their engine protection standards.

Crude's classification as either “light” or “heavy” depends on the oil’s relative density, based on the American Petroleum Institute (API) Gravity. This measurement reflects how light or heavy a crude oil is compared 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. Crude grades Crude oil comes in hundreds of different varieties or "grades." These grades are valued differently by refiners based on their crude qualities .
