In this study, we report on a basic study using oil film forming lubricant additives. With the aim of developing drivetrain lubricants having high efficiency for electric vehicles, we confirmed the effects of our newly developed additive and validated the working mechanism. The additive showed the effect of reducing friction in the mixed lubrication and improved efficiency of the reduction gear box and durability of parts. Furthermore, we confirmed that the friction reduction in the mixed lubrication is due to the prevention of metal contact between parts accompanying the improvement of the oil film thickness.
