Mobilgrease 28 is a wide-temperature, antiwear grease that combines the features of a polyalphaolefin (PAO) synthetic base fluid with an organo-clay (non-soap) thickener. 

 It is designed for the lubrication of plain and rolling bearings at low to high speeds, and splines, screws, worm gears, and other mechanisms where high friction reduction, low wear, and low lubricant friction losses are required. 

 It has a consistency between an NLGI No. 1 and No. 2 grease. 

 It has a recommended operating temperature range of -54ºC to 177ºC (-65ºF to 350ºF).
