What does API SN mean?
What does API SN mean?
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. 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.
What is the difference between API SN and API SN plus?
API SN Plus is a supplemental standard to the API SN specification, which introduces oils for LSPI (Low Speed Pre-ignition) mitigation. 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”).
What does API SN plus motor oil mean?
What is “API SN PLUS”? API SN PLUS is a new motor oil specification developed for turbocharged engines that is being developed in response to automakers request for motor oils that protect against Low-Speed Pre-Ignition (LSPI).
Is API SN plus backwards compatible?
The API SN Plus specification was created to quickly combat issues that come with newer TGDI engines and Low-Speed Pre-Ignition (LSPI) concerns. This new category is fully backwards compatible with API SN, because the “Plus” adds additional testing for the LSPI problem.
Can I use API SN instead of API SL?
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. However, you have to pay attention to the year of construction of the engine. API SN to SJ are for the most recent cars, API SH to SA for the older cars.
Can I use API SN instead of API SH?
SN oils provide higher levels of performance than all the other “S” oils. API Categories SA through SH are obsolete, and oils labelled SN can be used in their place.
Can I use API SN plus instead of SN?
Marketers with licensed SN PLUS oils may use SN PLUS in the lower half of the API Donut. Oils licensed by API as API SN with SN PLUS and Resource Conserving and ILSAC GF-5 are eligible to display the API Certification Mark Starburst.
Can I use API SN instead of SG?
The “S” series is composed of SA, SB, SC, SD, SE, SF, SG, SH, SJ, SL, SM and SN. SN oils provide higher levels of performance than all the other “S” oils. API Categories SA through SH are obsolete, and oils labelled SN can be used in their place.
Can I use API SP instead of SN?
API SP will be fully backward-compatible with previous API service categories, including API SN PLUS, SN, SM, SL or SJ.
Which is better API SN or API SL?
As explained earlier, the higher the letter, the more recent and a higher specification would supersede the lower ones. API SN to SJ are for the most recent cars, API SH to SA for the older cars. In this case, you need API SL, so an API SJ, lower, cannot be good. SM and SN supersedes SL so both oils can be used.
Is SP better than SN?
GF-6B oils replace 0W-16 oils. API SP replaces all API SN. This includes a timing chain wear test and fuel economy improvement test when using very low viscosity oils, among other tests.
What do you need to know about API SN?
Resource Conserving requires further properties like: The requirements of API SN with the Resource Conserving supplemental category are identical to the requirements of the ILSAC GF-5 standard. In order for an oil to meet the requirements of API SN or API SN/Resource Conserving it should satisfy the following test criterias:
When does API service SP need to be licensed?
Starting May 1, 2020, API Service SP may be licensed for use in the upper portion of the API Service Symbol “Donut,” and oils meeting SP with Resource Conserving requirements may be licensed to display “Resource Conserving” in the lower portion of the API Service Symbol in conjunction with API Service SP in the upper portion.
What are the new API standards for lubricants?
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.
When do new API standards go into effect?
API will accept applications for products meeting the new standards for a period of time prior to May 1, 2020 and will process applications as they are received, but the right to claim API licensing against the new standards will not be allowed until May 1, 2020.
