ABSTRACT:
An improved transparent lubricating oil composition, e.g., useful as a high severity metal cutting oil, comprises a major amount of oil of lubricating viscosity; a minor, effective amount of at least one sulfur-containing compound; and a minor, effective amount of elemental sulfur. Both the sulfur-containing compound and the sulfur are present in amounts to be soluble in the composition and the combination of sulfur-containing compound and elemental sulfur is present in an amount effective to improve the extreme pressure properties of the composition.
Improved methods of metal working using such compositions are also disclosed.
