Studies on lubricating oil are underway. As a fuel saving measure using lubricating oil, I! i! Lowering the viscosity with the intention of reducing friction loss, and (2) adding a friction reducing agent with the intention of reducing *t* loss under mixed lubrication and boundary lubrication are being considered. Particularly in the recent years of excellent fuel-saving oils, the addition of friction reducing agents has become essential, and many types of compounds have been developed to date and have achieved success.

能の低下が完全に起こらないとは言えなかった。Among the developed compounds, organic molybdenum compounds are particularly effective and most commonly used. The present inventors have also studied the use of this compound for many years, and as a result, they have confirmed that the addition of a molybdenum compound has an excellent fuel saving effect. However, during the course of the study, the following problems were discovered. That is, many molybdenum compounds exhibit excellent effects in fresh oil before deterioration, but as the oil deteriorates during engine operation, the fuel saving effect is gradually lost. The present inventors have found that, among molybdenum compounds, molybdenum dithiocarbamate is less likely to suffer from a decrease in fuel efficiency performance due to deterioration, but it cannot be said that the decrease in fuel economy performance due to deterioration has not yet completely occurred. There wasn't.
