When it comes to an oil change, ensuring you choose the right API classification is essential. Typically, an API SJ through SM engine oil would include some friction modifier. API Engine Oil Classification Look to your owner's manual. "Light" vs. "Heavy" Crude Oil Crude oil's classification as either “light” or “heavy” depends on the oil’s relative density, based on the American Petroleum Institute (API) gravity. The current and previous API Service Categories are listed below. Service fill oils for gasoline, light-duty diesel and heavy-duty diesel engines. 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.. Classification according to the API degree: Light crude oil: API gravity higher than 31.1 °API … Vehicle owners should refer to their owner's manuals before consulting these charts. API’s Engine Oil Licensing and Certification System ... Engine Oil Viscosity Classification, also play a critical role in defining the program. Therefore, the API maintains such diverse categories as API standard on precision thread gauges, compression-ignited engines (diesel) and oil. Oils may have more than one performance level. Breakdown of new and old classifications is included Includes bibliographical references (page 2) Caption title "Filing code: 1525 (P-401)." In this brochure the API Service Categories are summarised in easy to use charts. This defines whether an oil is suitable for gasoline or diesel engines. API Engine Service Classifications. The API SN category is an improvement over the API SM category in the following areas: For example the Iraqi Basrah Heavy oil has an of API Gravity of 23 (which place it as medium) yet it is being traded as heavy oil. Both a crude oil's viscosity and its API (American Petroleum Institute) degree are important parameters for classification. (2) Not required for Non-ILSAC viscosity grades. The classification is based on the results of the JASO T 904:2006 clutch system firction test. And SA is not hard to find mixed in with SM on the shelves at c-stores and others. Since 1930 there have been 12 different classifications of motor oil. • Main drivers for engine oil classification and specifications • Relevant industry groups and bodies • Specification overview – focus on Europe and North ... Oil marketers base oil suppliers ATIEL API JASO Additive companies ATC API, ACC Specifications ACEA API… API Engine Oil Classifications brochure . API’s outreach covers not only the oil and gas industry, but also any industry that has an impact on the petroleum interests. Classifications are made based on the sulfur content as well. The first of these was classified as SA, with further releases going up through the alphabet. This breakdown is based on the refining method and the base oil’s properties in terms of, among other things, viscosity and the proportion of saturates and sulfur content. The determination of whether a crude-oil blend is light or heavy is not always according to its API Gravity number. Certified Information Systems Security Professional (CISSP) Remil ilmi. The current and previous API Service Categories are listed below. API Engine Oil Classifications For Service Fill Oils Footnotes (1) Not required for SAE XW-16 and 0W-20. It specifies the viscosity grade required for your car's engine. Old motor oil and even some newer blends (when used in older engines) can cause harm to your engine. As shown above, API "SA" oil was the first in the API Service Classification for gasoline motor oils. Search. When you are choosing a transmission or gear oil you might be wondering what GL-4 and GL-5 mean and what the differences are between these two classifications. Official classifications. API Engine Oil Classifications brochure pdf 6.54 MB. The American Petroleum Institute (API) engine oil classification system was set up as a joint effort by API, ASTM (American Society for Testing and Materials) and SAE (Society of Automotive Engineers). Monitoring and Enforcement Program. Crude oil with low content of sulfur means ‘sweet’ and the presence of … API’s oil classification system API stands for American Petroleum Institute. (5) If API CI-4, CJ-4, CK-4 and/or FA-4 categories precede the “S” category API (American Petroleum Institute) specifications are often seen on oil containers and they show the minimum standard of oil that can be used in an engine. Informs automobile operators that API changed its classification system for motor oils. API has been testing packaged and bulk engine oils under its Aftermarket Audit Program (AMAP) since 1994. The recommended correct oil to use for all gasoline engines, in any year, is the classification SM. 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. Oils may have more than one performance level. Gasoline engines: The service level category contains two letters. Here's all you need to know about the API (American Petroleum Institute) engine oil classification and why is it adopted as one of the most common standards across the globe. Bitumen derived from oil sands deposits in Alberta, Canada, has an API gravity of around 8°. 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. Almost every lubricant used in plants today started off as just a base oil. Crude oil's viscosity can vary from a low-viscosity liquid to up to tar-like, nearly solid form. The API cautions that any oil with a classification of SE should not be used in engines built after 1979. The American Petroleum Institute (API) has categorized base oils into five categories (API 1509, Appendix E). Since 1924, the American Petroleum Institute has been a cornerstone in establishing and maintaining standards for the worldwide oil and natural gas industry. That's why it's important to understand API ratings. West Texas Intermediate (WTI) crude oil is a good example of sweet crude oil, while oil from Canada and the U.S. Gulf Coast tends to be sour. The designation API GL-1 denotes lubricants intended for manual transmissions operating under such mild conditions that straight petroleum or refined petroleum oil may be used satisfactorily. Stage Design - A Discussion between Industry Professionals. That's right, motor oil … The newest oils are the SN, brought out in 2011, and the SN Plus released in 2018. The new system is designed to promote improved communications between engine oil users, suppliers, and manufacturers. Get Free Api Engine Oil Classification now and use Api Engine Oil Classification immediately to get % off or $ off or free shipping. Medium oil is defined as having an API gravity between 22.3 °API and 31.1 °API Heavy oil is defined as having an API gravity below 22.3 °API.
