PENNZOIL LITHIUM COMPLEX GREASE WITH MOLY is a heavy duty, extreme pressure, high temperature grease formulated with a lithium complex thickener and high viscosity base oils. It contains molybdenum disulfide for optimum load carrying capabilities and reduced sliding friction. The molybdenum disulfide has a natural affinity for metal surfaces and provides residual dry film lubrication in the event that the grease itself is lost. The amount of molybdenum disulfide meets the requirements for Caterpillar off-highway equipment and the American Association of Railroads Specification AAR-M-929-69.*
