In Table 1, the lubricating oil shown in test number 5 is the lubricating oil of this example, in which iron halide FeCf3 is added to the phosphoric acid ester of the extreme pressure agent, but the lubricating properties are different from those of the conventional R12/alkylhenzene type. It was found that the wear amount was less than that of the previous model, and the performance was very good.
