Abstract:

With the continued modernization and improvements being made in the automotive industry, a new level of performance is required for engine oils. Engines are being built to be more durable, while also being designed for better fuel economy and to meet higher emission standards. The current GF-5 engine oil standard does not meet all the new requirements, specifically those of the USA Corporate Average Fuel Economy (CAFE) which will require the average fuel economy to be 54.5 MPG by the year 2025. While oils with lower viscosities can meet these fuel economy requirements, the oil must also maintain the engine durability, hence the need for the GF-6 performance levels.

Along with performance needs, the engine testing needs have also undergone a lot of recent changes. Older engine tests have been replaced with updated versions and brand new tests have been developed that will all need to be accounted for in the ILSAC GF-6 specification. Because of the significant number of new tests and requirements the GF-6 standard has seen numerous delays and is not expected to be finalized until Q2 of 2020. This poster will go deeper into the needs for the new GF-6 specifications along with the reasons why it has taken so long to achieve.
