ILSAC GF-6

Legislation to reduce emissions and improve fuel economy have been driving changes in passenger car hardware system design and engine operation, which places increased demands on the engine oil. These factors, combined with the demise of some of the engine tests used in ILSAC GF-5, were the key drivers for the new ILSAC GF-6 passenger car engine oil standard, which took effect on May 1 2020.
