"Two of the new standards, ILSAC GF-6A and GF-6B, are the latest in a line of more stringent performance specifications put forward by the International Lubricant Standardization Advisory Committee (ILSAC), and a third standard, AP SP, is API's latest engine oil performance standard. API SP includes all of the ILSAC requirements while at the same time provides performance requirements for oils that do not fall under ILSAC-member recommendations. The new standards specify more stringent engine oil performance requirements for spark-ignited internal combustion engines. All three of these standards can be licensed under API's Engine Oil Licensing and Certification System beginning May 1, 2020."
