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 kind of oil is API SN?

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).

When did API SN start?

API began licensing oils against the SN PLUS classification on May 1, 2018.

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”).

Can I use API SN instead of SG?

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.

What does API SN cover?

Can I use API SN instead of Sh?

Can I use API SP instead of SL?

API SP will be fully backward-compatible with previous API service categories, including API SN PLUS, SN, SM, SL or SJ.

How to access session state in ASP.NET?

You can access session state using a custom RouteHandler. Update: if your API functions read from session, and don’t modify session, it might be a good idea to use IReadOnlySessionState instead of IRequiresSessionState. This ensures the session isn’t locked during the processing of the API function.

How long does it take to access session in WebAPI?

You can easily test this out for yourself by just putting Thread.Sleep (5000) in a WebAPI method and enable Session. Run 5 requests to it and they will take a total of 25 seconds to complete.

Can a session go hand in hand with REST API?

Yes, session doesn’t go hand in hand with Rest API and also we should avoid this practices. But as per requirements we need to maintain session somehow such that in every request client server can exchange or maintain state or data. So, the best way to achieve this without breaking the REST protocols is communicate through token like JWT.

When did API Start Licensing oils against SN plus?

API began licensing oils against the SN PLUS classification on May 1, 2018. As marketers consider developing oils that comply with the SN PLUS classification, they should keep the following points in mind:
