In order to meet the rapid development of China’s passenger cars and increasingly strict regulations of fuel consumption limits, passenger car motor oils (PCMOs) formulated to improve the fuel economy of passenger cars, are needed by more and more OEMs. The presentation focuses on the effects of base oils, viscosity index improvers (VII) and friction modifiers on the fuel economy performance of engine oils by conducting the high frequency reciprocating rig test (HFRR) and engine torque test. The test results indicate that PCMOs with PAO base oils, VII of PMA and MoDTC can significantly improve the fuel economy of PCMOs.
