GF-6 Passenger Car Automotive Specification

GF-6 is an automotive specification for passenger car motor oils (PCMO) that was developed by ILSAC* (International Lubricants Standardization and Approval Committee). This specification is intended to:

Lower Viscosity Grades

Recently, improvements in engine hardware and manufacturing technology have allowed the use of lower viscosity grades in passenger car vehicles while maintaining engine durability. Additionally, the demand for better fuel economy has increased both end user and OEM interest in low viscosity engine lubricants. This has led to an increase in the use of 5W-20 and even 0W-20 viscosity grades over the thicker 10W-30 and 10W-40 grades. The trend to lower viscosities will continue with the introduction of a new viscosity grade in GF-6.

Actively Working on GF-6

Chevron Oronite has already tasked its chemists and engineers to the work of meeting or exceeding industry and customer expectations for the implementation of GF-6 for passenger cars.

* ILSAC was formed in 1992 by AAMA (American Automobile Manufacturers Association, representatives of DaimlerChrysler Corporation, Ford Motor Company and General Motors Corporation) and JAMA (Japan Automobile Manufacturers Association) to define the need, parameters, licensing and administration of lubricant specifications. Together with the Tripartite system (API, SAE and ASTM) they formed EOLCS (Engine Oil Licensing and Certification System). ILSAC oils often carry the API Service Symbol (Donut) including the Energy Conserving designation and/or API Certification Mark (Starburst).
