New engine technologies are constantly being developed and introduced in order to meet increasing customer demands and government regulations. In many cases, improved engine oil performance is necessary to facilitate the implementation of new engine technologies. In order to meet increasing customer demands for performance, durability, and fuel economy, the engine builders are introducing hardware and operating cycles that place increasing demands on the engine oil. Each new North American Gasoline Engine Oil Performance Category has been developed with specific performance targets and improvements in mind. This paper will primarily focus on the initial steps in the development of engine oils for the GF-6 passenger car engine oil category in North America. GF-6 is scheduled to be introduced during the 1st quarter of 2015 and will supersede GF-5 and previous categories. It will also be backward compatible and will provide improved performance relative to GF-5 in many respects.
