In 1970, along with the SAE and ASTM (American Society for Testing and Materials), they established the API Service Classification System to define the performance level of a given oil, unrelated in the main, to oil viscosity.The API requirements S for Spark Ignition (petrol) and C for Compression Ignition (diesel) can be briefly described as follows. Oil specific gravity = 141.5 131.5 + ° API = 141.5 131.5 + 36 = 0.845. That's why it's important to understand API ratings. Though API values do not have units, they are often referred to as degrees. And just like kilometers and miles, neither is … API Classifications API Oil Service Categories. CI-4 - … If an automotive owner's manual calls for an API SJ or SL oil, an API SM oil will provide full protection. It reunites different actors in the production, refinement, distribution and many other activities around ptroleum. The greater the API, the less dense the liquid. API stands for American Petroleum Institute. Using motor oil that meets all automobile manufacturers’ warranty requirements is a key factor in developing repeat customers and safeguarding against unhappy customers with damaged engines. Conversion calculator API - specific gravity Crude oil viscosity as function of gravity - Viscosity at 20°C/68°F and 50°C/122°F for more than 120 crudes is shown as function of specific gravity@15°C/60°F JASO-MA oils don’t contain friction modifiers. API SP . Density, specific gravity (SG) and API gravity* values are used to monitor quality during the production of crude oil, and to establish its price in trading. In 2010 the American Petroleum Institute introduced a new engine oil category under the name API SN and a new supplemental category called Resource Conserving. Since 1924, the American Petroleum Institute has been a cornerstone in establishing and maintaining standards for the worldwide oil and natural gas industry. This application describes the fully automatic measurement of density, SG and o API of light crude oil at 15 °C and heavy crude oil at 90 °C and 50 °C. A specific gravity scale developed by the American Petroleum Institute (API) for measuring the relative density of various petroleum liquids, expressed in degrees. Our lubricant products are marketed under the brand name of AP Oil and SINO (literally signifying Singapore Oils). In the oil industry, specific gravity is a common quality specification for finished products. Does it matter? API gravity = 141.5/SG – 131.5. Low prices, Fixed delivery price for UK and EU countries. Our float switch product line lists the specific gravity (SG) which the device will be able to float. They both can be used to measure the gravity of a fluid, such as hydraulic oil, in the same way that miles or kilometers can both be used to measure distance. Prior to that, in the days of API SG (1989) many manufacturers already had put a 0.10% (1000ppm) limit on Phosphorus. Determine the oil gradient. From there, it moved to SB, SC, SD, and so on (skipping only SI and SK). The API Engine Oil Licensing and Certification System provides a simple designation of letters and numbers that allows engine manufacturers and oil marketers to clearly provide users with the information they need to ensure that the proper oil … The following Nulon products are suitable for the specification API SG.

AP Oil International Limited, formerly known as Huan Chew Oil Trading Pte Ltd, we have three lubricant blending plants (two in Singapore, one in Vietnam) producing a wide range of lubricants for automotive, industrial and marine applications. Think of it this way, when cars were first built, the oil they required needed an API SA Service Classification. So the API gravity of West Texas Intermediate is said to be 39.6 degrees. Gasoline engines: The service level category contains two letters. The API SN category is an improvement over the API SM category in the following areas: High temperature deposit protection for pistons; Better sludge control Density is defined as mass per unit volume of a fluid. API gravity moves inversely to density, which means the denser an oil is, the lower its API gravity will be. Liquids with a density lower than water, which includes most crude oil grades and petroleum products, will have a specific gravity between 0.0 and 1.0. API gravity is graduated in degrees on a hydrometer instrument and was designed so that most values would fall between 10° and 70° API gravity. API Gravity - API gravity express the gravity or density of liquid petroleum products. 1. API CJ-4 oils exceed the performance criteria of API CI-4 PLUS, CI-4, CH-4, CG-4, and CF-4 and can effectively lubricate engines calling for those API Service Categories. JASO MA – This was the standard for single unit engines where the wet clutch, gearbox and engine used the same oil. API gravity = (141.5/Specific Gravity) – 131.5. API SN Engine Oil Category. : MN7405-5 * These numbers are for comparison purposes … rev-1 lubricants. The American Petroleum Institute (API) is the only national trade association that represents all aspects of America’s oil and natural gas industry. So if you buy an engine oil meeting only API SA, it's an engine oil formulated for use in vehicles built in the 1920s. The American Petroleum Institute established API gravity as a measure of the density of petroleum liquids relative to water. This defines whether an oil is suitable for gasoline or diesel engines. API SP will be fully backward-compatible with previous API service categories, including API SN PLUS, SN, SM, SL or SJ. Performance specification The product meets the following specifications: ♦ API SG/CF-4 ♦ GB 11121-2006 SG, GB 11122-2006 CF-4. SP is the API’s newest service category. Always check your owner’s manual for the manufacturer’s recommended oil viscosity grade, API service classification and any builder approval. ♦ Low volatility, reducing consumption of engine oil ♦ Good compatibility with rubber, effectively protecting sealed material against leakage.

However, for crude oil grades, the API … Our more than 600 corporate members, from the largest major oil company to the smallest of independents, come from all segments of the industry. The relative density of petroleum liquids can also be uncovered by using API gravity value: RD at 60 o F = 141.5 / (API gravity + 131.5) A key formula for establishing barrels of crude oil per metric ton. While it is not traded on a market like Brent Crude or West Texas Intermediate (WTI), it is often used as an oil marker for Asia and Australia.. Have to do an oil change so wondering if I should switch? When using CJ-4 oil with higher than 15 ppm sulfur fuel, consult the engine manufacturer for service interval. API Service Level Category . The American Petroleum Institute gravity, or API gravity, is a measure of how heavy or light a petroleum liquid is compared to water: if its API gravity is greater than 10, it is lighter and floats on water; if less than 10, it is heavier and sinks.. API gravity is thus an inverse measure of a petroleum liquid's density relative to that of water (also known as specific gravity). Wondering if the API classification really matters. American Petroleum Institute: API SG. Specific gravity and API gravity are both measurements of density. 1. n. [Enhanced Oil Recovery, Heavy Oil] A specific gravity scale developed by the American Petroleum Institute for measuring the relative density of various petroleum liquids, expressed in degrees.API gravity is gradated in degrees on a hydrometer instrument and was designed so that most values would fall between 10° and 70° API gravity. Full Synthetic 0W-40 High Performance Engine Oil (SYN0W40) Full Synthetic 5W-20 Fuel Conserving Engine Oil (SYN5W20) Full Synthetic 5W-30 Long Life Performance Engine Oil (SYN5W30) API hydrometers were developed for crude oils and are defined at 60 F. The specific gravity (SG) also was defined at 60 F as the density of a fluid at 60 F referred to the density of water at 60 F. Thus, direct conversion between the API gravity and specific gravity is possible. For automotive gasoline engines, the latest engine oil service category includes the performance properties of each earlier category. The density of crude oil and liquid hydrocarbons is usually reported in terms of specific gravity (SG) or relative density, defined as the density of the liquid material at 60°F (15.6°C) divided by the density of liquid water at 60°F.
