What is the highest api oil rating

The service rating of passenger car and commercial automotive motor oils is classified by the American Petroleum Institute (API). The program certifies that  The API SN rating is equivalent to the new GF-5 oil rating by the International The specification calls for a high quality synthetic base stock with additives that 

You can't really use the API specifications to measure the quality of an oil as many of the top end ester based oils meet API SL rather than the latest API SM  28 Dec 2018 API SN PLUS, which is defined as a “classification,” identifies oils that meet API SN and are also formulated to provide additional protection  1 Jan 2009 When purchasing oil, the oil has a quality level (API Service). the top-of-the-line motor oil was rated SG, so that's what Ford called for. 1 Aug 2019 The story behind API's engine oil certification. additive qualities in addition to the SAE viscosity classifications already in use. API There are tests to measure an oil's performance in higher temperature parts of the engine.

The API SN rating is equivalent to the new GF-5 oil rating by the International The specification calls for a high quality synthetic base stock with additives that  5 Nov 2015 Data Sheet. But what does API SN or API SL/CF mean exactly? For recent oil , the higher specification will supersede the lower letter grade. For example Gasoline (or Petrol) Engine Service Classifications. Below are all  The API's current highest rating for motor oil is SM. This oil is intended for all gasoline engines currently in use and has been the standard since 2004. For diesel  In the USA, the API oil classification system provides a simple designation for Cooled EGR creates increased demand on the engine oil through higher oil  13 Oct 1995 It also says never to use non-detergent oil, or oils labeled API SA, SB, Oils with higher service classifications may be substituted for oils with 

When you see a W on a viscosity rating it means that this oil viscosity has been tested at a Colder temperature. The numbers without the W are all tested at 210° F or 100° C which is considered an approximation of engine operating temperature. In other words, a SAE 30 motor oil is the same viscosity as a 10w-30 or 5W-30 at 210° (100° C).

Licensed from May 1, 2018, API SN Plus is a new API classification that can be used alongside API SN, API SN with Resource Conserving and ILSAC GF-5. It was developed in accordance with OEMs request for motor oils that can protect from the potentially catastrophic effects of Low-Speed Pre-Ignition (also known as LSPI, more info here ). API Introduces Three New Gasoline Engine Oil Standards, ILSAC GF-6A, GF-6B, and API SP API’s Lubricants Standards Group approved by letter ballot the adoption of two new ILSAC specifications, GF-6A and GF-6B, and a new API Service Category, API SP. 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. Generally speaking, oil with an API gravity between 40 and 45° commands the highest prices. Above 45°, the molecular chains become shorter and less valuable to refineries. [4]
