API Announces Plans for SN PLUS in Donut

Last Monday at the annual meeting of the Independent Lubricant Manufacturers Association (ILMA) in Orlando, Kevin Ferrick, Sr. Manager of the API Engine Oil Program, announced that a proposed supplement to API Service Category SN dubbed SN PLUS will be licensable for use in the API Service Symbol donut when SN PLUS is approved by the API Lubricants Group.

The SN PLUS supplement to API SN is intended to identify oils that meet API SN and provide additional protection against low-speed pre-ignition in turbocharged direct injection gasoline powered engines. OEMs sent a letter to API stating "Low speed pre-ignition is of concern to all the companies (OEMs) listed below and there is an immediate need for preventive action to reduce/eliminate the occurrence of oil derived low-speed engine pre-ignition. This is needed to protect the numerous turbocharged direct injection engine powered vehicles on the road today that are experiencing and being damaged by LSPI.  

A letter dated July 20, 2017, from Ron Romano of Ford Motor Co., chairman of the ILSAC/Alliance LWG, to Kevin Ferrick of the American Petroleum Institute stated "I'm writing this on behalf of the companies copied below to formally request that the American Petroleum Institute (API) develop a supplement to the existing ILSAC GF-5 Standard to include Low Speed Pre-ignition (LSPI) protection. We request this supplement include all the performance requirements presently in ILSAC GF-5 plus the Ford Low Speed Pre-ignition Engine test with a maximum average number of events of 5. SAE 0W-16 should be included in this supplement." Those other companies included FCA US LLC, Toyota Motor Corporation, Mitsubishi Motors Corporation, Honda Motor Co. Ltd., Nissan Motor Co., Ltd., General Motors Co., Mazda Motor Corporation, Daihatsu Motor Co., Ltd., Subaru Corporation and Suzuki Motor Co., Ltd. "Low speed pre-ignition is of concern to all the companies listed below and there is an immediate need for preventive action to reduce/eliminate the occurrence of oil derived low-speed engine pre-ignition. This is needed to protect the numerous turbocharged direct injection engine powered vehicles on the road today that are experiencing and being damaged by LSPI. Due to delays in the development of ILSAC GF-6 we feel it is necessary to incorporate LSPI protection into a category/standard as soon as possible." "We request first licensing of this supplemental category/standard by January 1, 2018. We feel this is achievable since the Low Speed Pre-ignition Test has already been developed and approved to be published as an ASTM procedure and candidate testing can start immediately."

Licensed marketers will be able to use the Service Symbol Donuts below to help consumers identify SN PLUS motor oils.
