While automotive companies are eager to develop electric vehicle, many studies of fuel economy improvement by internal combustion engine are still going on now. Development of fuel economy engine oil is among them. To apply low viscosity base oil for engine oil contributes to reduce viscous resistance and then improves fuel economy. In that case, fuel economy performance can be enhanced by using proper friction modifier. In this paper, Molybdenum Dialkyldithiocarbamate which is widely used for friction modifier in fuel economy engine oil is introduced.
