3833573: The Effect of Friction Modifiers Under Ultra Low Viscosity Engine Oils Kenji Yamamoto, Kouichi Takano, Shinji Iino, ADEKA Corporation, Tokyo, Japan
Electrified ICE equipped vehicles are considered to be important to reduce the CO2 emission for coming decades. Since HEV are operated under low temperature more frequently, the effect of ultra-low viscosity engine oil for FEI would be more significant. Ultra low viscosity engine oils such as 0W-8 are introduced to Asian market in 2019 with JASO GLV-1, and these viscosity grades are under discussion for implementing ILSAC specification as well. The effect of friction modifiers with those ultra-low viscosity engine oils are significantly higher than with conventional viscosity grades because of their more frequent contact of surfaces. In this study, friction reduction performances of several friction modifiers with 0W-8 and 0W-20 formulated with GF-6 additive technology are evaluated under bench tests and motored engine friction tests. As a result of study, MoDTC exhibited significant friction reduction performance compared to other FM technologies especially with 0W-8 viscosity grade.
