API SQ and GF7 Engine Oils Are Coming!

Understanding the Transition: GF6 to GF7 and API SP to SQ Lubricant Standards In this episode, we explore the upcoming changes in engine oil standards from API SP to SQ and from ILSAC GF6 to GF7. We delve into the role of the American Petroleum Institute (API) and ILSAC in setting these standards and compare them with European practices. We trace the historical developments from GF4 to GF6, emphasizing their focus on emissions control and fuel efficiency. The video explains the evolving performance criteria, especially regarding LSPI (low-speed pre-ignition) with a new focus on aged oils. We break down the differences in viscosity grades under GF7a and GF7b, discuss fuel economy tests, and how formulation changes in existing oils can meet these new standards. 00:00 Introduction to New Engine Oil Standards 00:30 Understanding the Regulatory Bodies 01:06 Historical Context and Evolution 02:26 Performance Metrics and Testing 03:27 Detailed Changes in GF7 Standards 06:29 Formulation Changes and Market Impact
