Looking at GF-6 The GF-6A standard encompasses oil that ILSAC designated to be backward compatible, which means GF-6A covers the current API SN oil viscosities of 0W-20, 5W-20, 5W-30, and 10W-30. SN PLUS: Current: On November 9, 2017, the API Lubricants Standards Group approved the adoption of SN PLUS, a new classification that may be used in conjunction with API SN and API SN with Resource Conserving. The latest American Petroleum Institute (API) specification, API SP, took effect in May 2020. The API SN PLUS motor oil specification is intended to complement API SN and ILSAC GF-5 and aimed at addressing the increasing impact of Low-Speed Pre-Ignition in … The designation for this supplement appears at the bottom of the API Service Symbol, but it does not impact ILSAC GF-5 or the API Certification Symbol ("Starburst"). LSPI (a kind of ‘knocking’) is a known risk with these types of engines. SN: Current API SN PLUS RESOURCE CONSERVING. As explained earlier, the higher the letter, the more recent and a higher specification would supersede the lower ones. a supplemental standard API SN Plus is a supplemental standard to the API SN specification, which introduces oils for LSPI (Low Speed Pre-ignition) mitigation. API SP . An engine oil with the right formulation helps to prevent LSPI. Service fill oils for gasoline, light-duty diesel and heavy-duty diesel engines. As did ILSAC GF-6, the latest spec from the International Lubricants Standardization and Approval Committee. Low-Speed Pre-Ignition (LSPI) is an abnormal combustion phenomenon observed at low engine speeds in which the fuel/air mixture in the combustion chambers ignites before spark timing. This requirement contains an additional element to protect the engine against ‘LowSpeed Pre-Ignition’ (LSPI). The API SN PLUS specification was requested by the automobile industry to protect passenger vehicles from low-speed pre-ignition (LSPI). Total is ready for the initial available upgrade of API SN Plus and will have all appropriate TOTAL QUARTZ products certified as API SN Plus before the official launch date. Performance Plus® Synthetic Blend 5W-20 SN Plus/GF-5 is a high-performance synthetic blend engine oil designed with superior Group II+ base oils and high-quality additives to: provide better low-temperature performance and protection and meet or exceed the demands of gasoline and propane engines in passenger cars and light duty trucks. Before the October 1, 2010, introduction date, oil marketers may license API SN oils as API SM. Oil companies changed their additive packages in such a way that would prevent the fuel-oil mixture from combusting and thus preventing the uncontrolled combustion. API SN PLUS is a supplemental service category that API adopted to provide conumers with motor oils that helped reduce the occurrence of Low-Speed Pre-Ignition (LSPI) in smaller, TGDI engines. API SP. These are the new proposed seals for the latest API specification, "SP", which will equate to the ILSAC GF-6B specification. The GF-6 specification is currently in development, and is intended to be backwards compatible with GF-5, but in the meantime, the industry will release API SN PLUS. “API SN Plus Resource Conserving, which includes modifications to address issues specific to TGDI engines, further demonstrates API’s recognition of the need and reaction with a more timely solution for the marketplace, which is a contrast to the protracted development process for … The American Petroleum Institute (API) has announced that May 1, 2018 will be the first licensing date for API SN Plus. According to API, SN-PLUS are formulated to provide API SN performance and additional protection against low-speed pre-ignition for engines with direct injection and turbocharging. Presentations. Its GM dexos1 Gen 2 specification took effect Aug. 31, 2017. It occurs in today’s advanced engines and … SN-PLUS oils can effectively lubricate engines calling for API SN, API SN with Resource Conserving or ILSAC GF-5. API SN Resource Conserving. Engine oil requirement, specially developed for TDGI engines. API Engine Oil Classifications brochure . API SP will be fully backward-compatible with previous API service categories, including API SN PLUS, SN… The SN PLUS Service Category was introduced as a supplement to API SN specification in 2018 to mitigate low speed pre-ignition (LSPI) events in Turbocharged Gasoline Direct Injection (TGDI) engines. Designed for modern petrol engines, SynPower 5W-30 meets the ILSAC GF-5 fuel efficiency specification and the GM dexos1™ GEN 2 specification. MPM has the products with the API SN Plus specification for you: The current MPM portfolio contains two products with an ‘SN Plus’ specification: Why API SN PLUS? FORD WSS-M2C961-A1 Properties and Specifications. In addition to the API, the ACEA (the association of European car manufacturers is currently also assessing the addition of a standard LSPI test in the next ACEA requirement. API SN Plus is still being defined, but Shell believes that its dexos1 Gen 2 formulations will meet its requirements. ILSAC GF-6A. ADD OIL (M) SDN BHD: 4S PROFESSIONAL: 5W-30: SP: Resource Conserving, SN PLUS: GF-6A: ADD OIL (M) SDN BHD: 4S PROFESSIONAL: 5W-40: SP: Resource Conserving, SN PLUS MPM has the products with the API SN Plus specification for you: The current MPM portfolio contains two products with an ‘SN Plus’ specification: API CJ-4 oils exceed the performance criteria of API CI-4 with CI-4 PLUS, CI-4, CH-4, CG-4 and CF-4 and can effectively lubricate engines calling for those API Service Categories. Such LSPI events can cause engine knocking, decreased efficiency, and in the worst case, catastrophic failure due to cracked pistons. Starting October 1, 2010, oils that have passed the tests for API Service Category SN at the limits shown in Table G-5 and are properly licensed by API may display API Service SN in the upper portion of the API Service Symbol. It is the combination of direct injection PLUS turbo charging (TGDI) that has necessitated the requirement for specifications like API SN PLUS. API SN PLUS API Service Category SN PLUS was introduced in May 2018 as a supplement to API SN and ILSAC GF-5 to ensure that engine oils properly protect against low speed pre-ignition (LSPI), a severe engine performance issue that affects gasoline direct injected (GDI) … It also meets the latest API SN PLUS specification and is suitable for use in GDI/TGDI (Gasoline Direct Injection and Turbocharged Gasoline Direct Injection) engines where it protects against engine wear and Low Speed Pre-Ignition (LSPI). API SP Resource Conserving. Sign up … The American Petroleum Institute introduced a supplement to their API SN specification – called API SN Plus – that also includes tests to verify that the oil protects against LSPI. As soon as this supplemental category is defined and the testing protocol for the API SN Plus license is available, Shell will seek API SN Plus approvals for the following products and expect to claim API SN Plus for them on first use date: What is Low-Speed Pre-Ignition? Click for more details. It is meant for 1995 and older engines. LSPI is the spontaneous ignition of the fuel/air mixture prior to spark-triggered ignition. For the most part, it mirrors API specifications. This new supplemental specification, known as API SN PLUS, includes the testing protocol for API SN and a special test for LSPI, the API Sequence IX test. API began licensing oils against the SN PLUS classification on May 1, 2018. SP is the API’s newest service category. In addition to the API, the ACEA (the association of European car manufacturers is currently also assessing the addition of a standard LSPI test in the next ACEA requirement. Specifications from SA to SH are considered obsolete, meaning that you cannot get any official license from the API. API SN PLUS is a new standard (!)
