Mobilgrease 28 is a supreme performance, wide-temperature, antiwear grease designed to combine the unique features of a polyalphaolefin (PAO)
synthetic base fluid with an organo-clay (non-soap) thickener. Its consistency is between an NLGI No. 1 and No. 2 grease. It offers outstanding
performance over a wide temperature range. The wax-free nature of the synthetic base fluid, together with its high viscosity index compared to mineral
oils, provide excellent low temperature pumpability, very low starting and running torque, and can help reduce operating temperatures in the load zone of
rolling element bearings. The clay thickener gives Mobilgrease 28 a high dropping point value of around 300?C, which provides excellent stability at high temperatures. Mobilgrease
28 resists water washing, provides superior load-carrying ability, reduces frictional drag, and prevents excessive wear. Tests show that Mobilgrease 28
lubricates effectively rolling element bearings under conditions of high speeds and temperatures. Mobilgrease 28 has also shown excellent ability to
lubricate heavily loaded sliding mechanisms, such as wing flap screw jacks. For more than 30 years, Mobilgrease 28 has been the multi-purpose grease of choice for military and related aviation applications, worldwide.
