What is the difference between GF5 and GF6 engine oil?

[LucasLee]

Introduction to the differences between GF5 and GF6 engine oil: Viscosity grade: The viscosity grade of GF5 engine oil is 1000, while that of GF6 is 5000. Performance aspects: GF6 has undergone many improvements compared to GF5, including fuel economy and fuel efficiency, engine durability, wear protection, prevention of low-speed pre-ignition (LSPI), reduction of timing chain wear, turbocharger deposit control, and sludge reduction. Additional information: Strict emission and fuel economy regulations drive changes in passenger car hardware system design and engine operating conditions, placing higher performance demands on lubricants, including new dimensions of hardware protection, which means OEMs require more powerful engine oil.
