Background/Additional Information:
The ILSAC or International Lubricant Standardization and Approval Committee, see website www.ilma.org/resources/ilac_finalstd0l 1404. pdf and
http://www. performance oil technology.com/ilsacandgfoils.htm for a history of the API, SAE, and JASO that now are all part of the International
Committee ILSAC. The ILSAC website has the complete explanation of the new GF-4 standards which were set on January 14, 2004. What is most
important is the GF-4 ILSAC standard meets the latest U.S. Governments standards for fuel economy and long term emissions system performance and
durability. It is very important that all dealers are using the correct oil in our vehicles. We are aware that dealers are purchasing engine oil in bulk and
they need to contact their suppliers to ensure the engine oil supplied meets the proper GF-4 standards. You can use the following Oil Manufactures
websites for more information.
