Summary:

This paper describes lubricant technology to enhance the durability of the low friction performance of gasoline engine oils which were formulated with molybdenum dithiodicarbamates (MoDTCs) as friction modifiers. This paper also describes an evaluation method which consists of three tests: (1) Our in-house rig test to simulate oil deterioration in an engine stand; (2) Quantitative analysis of MoDTC and ZnDTP in oils and; (3) A friction test (SRV). It was found that the low friction performance of fuel economy engine oils deteriorated primarily due to the consumption of MoDTC and ZnDTP. Calcium salicylates had better durability of low friction performance than calcium sulfonates. Furthermore, sulfurized compounds enhanced the durability. Based on these findings, an experimental oil was formulated. Since this oil achieved a durability of 10000 km in the engine stand test, it was concluded that the durability performance was improved through the lubricant technology by approximately 6000 km
