GF-6 is the newest
ILSAC engine oil performance standard aimed at improving fuel economy and enhancing engine capabilities for passenger cars. This new standard will replace the current ILSAC GF-5 standard. Every new level of standard is backward compatible with the previous generation.
GF-6 will provide low-speed pre-ignition (LSPI) and timing chain wear protection while improving piston cleanliness and fuel economy.
