摘要:
Lubricated surfaces and lubricant compositions for lubricating a surface. The lubricated surface is provided by a lubricant composition including a base oil of lubricating viscosity, at least one metal salt of phosphorothioic acid, and an ashless, sulfur-free organophosphorus compound providing a metal to phosphorus weight ratio ranging from about 0.25:1 to about 1.0:1 by weight. The lubricant composition is substantially devoid of molybdenum.
