Abstract
A lubricating grease composition including the combination of an oil base, a thickener, and bismuth preferably in the form of a bismuth carboxylate. The grease has excellent film strength, improved “anti-washout” capabilities, and, depending on the thickener used, may have no dropping point, meaning that the oil will not separate out at elevated temperatures.
