The load carrying ability of the lubricating oil base is substantially increased by the inclusion therein of the minor proportion of the extreme pressure addition agent, which is one whose effectiveness is dependent upon its ability to react chemically with the metallic surfaces to be lubricated, while the inclusion of the corrosion inhibitor does not substantially decrease the extreme pressure proportions imparted by the extreme pressure addition agent. The lubricating oil base may be of mineral, animal, vegetable or synthetic origin or may comprise a mixture of mineral and non-mineral oils. Those fatty acids, such as oleic acid, which are oily ...
