In the present study, the effect of lubricating oils with Mo additives on the tooth surface failure of heat-treated and case-hardened spur gears was investigated using a power-circulating-type gear-testing machine. The lubricating oils used in this experiment are of six kinds, namely a base oil (SAE 90) and five lubricating oils that are made by adding the extreme-pressure additives of S-P, MoS_2, MoDTC, S-P-MoS_2, and S-P-MoDTC to the base oil, respectively. Consequently, it was found that all of these extreme-pressure Mo additives increase the endurance limit of pitting fatigue failure, though only MoS_2 additive decreases the load-carrying capacity for scoring. MoDTC lubricating oil with no particles increases the antiscoring performance in comparison to MoS_2 oil with particles, but the pitting fatigue failure for MoDTC oil is larger than that for MoS_2 oil.
