The Fuel Economy Improvement Effect of MoDTC with Low Viscosity Engine Oil under Hybrid Electric Vehicle

In order to confirm friction and fuel economy performance of engine oils, laboratory bench tests, motored engine tests and chassis dynamo tests with HEV under WLTP were conducted. The fuel economy improvement effect of reducing viscosity and MoDTC were confirmed under these tests. Moreover, MoDTC (std.) exhibited excellent fuel economy improvement effect compared to MoDTC (L) under low temperature condition particularly. Low viscosity oils formulated with MoDTC (std.) showed superior fuel economy performance even at HEV with relatively lower oil temperatures in this study.
