api sm vs sn

API has drafted and circulated for comment user language for the new API SN Plus ‘supplement.’ The user language defines the category and will become part of API 1509 — which describes the voluntary API Engine Oil Licensing and Certification System and explains to marketers how different API marks are licensed and displayed for the consumer. API SN | ILSAC GF-5 Engine Oils PSC offers Engine Oils that meet or exceed the requirements of ILSAC GF-5 & API Service SN with Resource Conserving. Where only API SM is claimed these oils are typically high HTHS (≥ 3.5cP) SAE 10W-40, 15W-40 and 20W-50 based on API Group I or Group II base oils. I have a new Craftsman lawn tractor (model 917.28856). Since 1924, the American Petroleum Institute has been a cornerstone in establishing and maintaining standards for the worldwide oil and natural gas industry. However, you have to pay attention to the year of construction of the engine. API continues to license engine oils against API SM and it is considered to be a current specification. When purchasing oil, the oil has a quality level (API Service). API SP with Resource Conserving matches ILSAC GF-6A by combining API SP performance with improved fuel economy, emission control system protection and protection of engines operating on ethanol-containing fuels up to E85. If you have a vehicle which was built after 1994, you should check in the categories from CD to CJ-4. short answer is no, API classifications are backwards compatible I think you might find it hard to find an SF,SG,SH or even an SJ rated oil SL was a classification released in 2001 so if they recommend SF,SG,SH,SJ, and SL then SM or SN or the next one which I believe is SN Plus should be ok var sm = new sn_ws.RESTMessageV2("","get"); //Might throw exception if message doesn't exist or not visible due to scope. While API SP is backwards-compatible to previous API service categories, motor oils will still be able to be licensed as meeting the API SN PLUS, SN, SM, SL or SJ categories. Let’s see by category how it works. Few examples to illustrate what would be the best: - Example 1: Car from 1987 and you only have two available oils, one with API SH, the other one with SL. It is for 2-stroke or 4-stroke engines. If an automotive owner's manual calls for an API SJ or SL oil, an API SM oil will provide full protection. The SN standard refers to a group of laboratory and engine tests, including the latest series for control of high-temperature deposits. For example, if we have an oil with specification SN, it can also be used for vehicles which request API SM, SL and SJ; it is backward compatible. For both, the letter S or C is followed by another letter. In some cases oils meeting API SM also carry an Energy Conserving claim to show that the oil has been formulated to improve fuel efficiency. There are many different categories/types, such as SG/CD, SF, SM, SA, SB, SC, SE, to list a few. Generally speaking, the best would be to follow the recommendation of the table. For recent oil, the higher specification will supersede the lower letter grade. The Netherlands 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. The primary weakness if the API system is the inability to position one approved products as an upgrade to another. SM et SN remplacent SL ainsi ces deux huiles peuvent être utilisées. Gasoline engines: The service level category contains two letters. In some cases oils meeting API SN also carry a Resource Conserving claim to show that the oil has been formulated to improve fuel efficiency. The concentration of magnesium in the fifteen API SN PLUS samples examined by PQIA ranges from 373 to 1,445ppm, with an average of 691 ppm. Specifications from SA to SH are considered obsolete, meaning that you cannot get any official license from the API. If you want to have more details about API and their lubricant program, check there website. Conditions SL: Current For more information on API SM, contact your Lubrizol representative. Category S is for “Spark Ignition”, for Gasoline and category C is for “Compression Ignition’, for Diesel. 6902 PJ Zevenaar Тесты по износу для API SM/SN жестче, чем для API SL. SM and SN supersedes SL so both oils can be used. SN CURRENT Introduced in October 2010 for 2011 and older vehicles, designed to provide improved high temperature deposit protection for pistons, more stringent sludge control, and seal compatibility. This defines whether an oil is suitable for gasoline or diesel engines. Today when I purchased oil, all the available viscosities and brands were SM. var response = sm.execute(); //Might throw exception if http connection timed out or some issue with sending request itself because of … BTW: NL854000562B01, Copyright © 2020 - 2021 Rymax Lubricants Масла API SL сильнее и лучше защищают от износа, чем масла API SN.Это не так. Technical questions API Service Level Category . - Example 2: Car from 2003 and you have different oils available: API SJ, SM or SN. This leads to API SM being seen to a wide range of lubricants of different performance levels and viscosity grades. 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 … Можно посмотреть таблицу с тестами для различных стандартов API. API SN is the latest specification to which motor oils intended for spark-ignited engines should adhere since 2010. It is important to note that although there is a clear increase in the amount of magnesium in API SN PLUS samples tested and lower levels of calcium, and that calcium is an antagonist and magnesium helps mitigate LSPI, it would be inappropriate to … Below are all the categories in Diesel. SN: Current: For 2020 and older automotive engines: SM: Current: For 2010 and older automotive engines. As for the S category applies: the higher the letter, the more recent and it is backward compatible. The higher the letter, the more recent the technology of the oil. It is mainly for passenger car, as most of the cars in US are Gasoline and not Diesel. If the engine is too old, modern chemistry might not be adapted or compatible with old engine designs and materials used to make the engine. API SN with Resource Conserving matches ILSAC GF-5 by combining API SN performance with improved fuel economy, turbocharger protection, emission control system compatibility, and protection of engines operating on ethanol-containing fuels up to E85. Licensed from May 1, 2018, API SN Plus is a new API classification that can be … In theory, both SH and SL could be used. API SN to SJ are for the most recent cars, API SH to SA for the older cars. SM is a later designation, probably due to some additive being removed. If for example an engine requires an API CG-4 and you have only a CI-4 oil available, CI-4 will cover the needs of CG-4, as stated in the table. API SN PLUS is the interim spec within the lubricants industry that supplements the API SN category for gasoline engine oil performance. Oils that satisfy API Service Category SN are superior in performance to those meeting API SM and earlier and can effectively lubricate engines calling for those Service Categories. SM: GF-4 . Mobil Special Oils are available in two multi-viscosity grades: SAE 15W-40 and 20W-50. As explained earlier, the higher the letter, the more recent and a higher specification would supersede the lower ones. API is mentioned on our Technical Data Sheet. For diesel engines, the latest category usually - but not always - includes the performance properties of an earlier category. SAE 5W30 API SN/ SM / SL GASOLINE ENGINE OIL is an advanced full synthetic engine oil designed to keep your engine running like new by providing exceptional wear protection, cleaning power and overall performance. It helps bridge the gap between current ILSAC GF-5 and future ILSAC GF-6 specifications. In this case, you need API SL, so an API SJ, lower, cannot be good. Shell Helix Ultra SN 5W-30 Fully synthetic motor oil – The next oil generation for engine cleanliness. As also explained earlier, more modern oils are not necessarily adapted for older engines. This will help to keep motorcycles running clean and protected in extreme operating conditions like racing. If I was going to use non-synthetic, I'd use CG, CH, or CI oil rated for diesel crankcases bought right off the Walmart shelf. If you read the table properly, the car needs an API SF.
