<p>The present invention relates to lubricant compositions containing phosphorus and sulfur free organotungstates. The organotungstates are defined as either the reaction product of a mono-or diglyceride and a tungsten source, or as the reaction product of a secondary amine, a fatty acid derivative, and a tungsten source. These compositions exhibit improved antiwear, corrosion, and antioxidancy properties, particularly in low phosphorus and low sulfur environments.</p> |
