Mobilgrease 28 is a supreme performance, high temperature, antiwear grease combining the unique features of a polyalphaolefin (PAO) synthetic base fluid with an organo-clay (non-soap) thickener. The wax-free nature of the synthetic base fluid, together with its low coefficient of traction compared with mineral oils, provide excellent low temperature pumpability, very low starting and running torque, and the potential to reduce operating temperatures in the load zone of rolling element bearings. The clay thickener provides excellent stability at high temperatures and Mobilgrease 28 has a high dropping point value of 260ºC. In addition, it resists water washing, provides superior load-carrying ability, reduces frictional drag, and prevents excessive wear. Tests show that Mobilgrease 28 prevents friction oxidation (fretting) and lubricates rolling element bearings under conditions of high speeds and temperatures. It has also shown superior ability to lubricate heavily loaded sliding mechanisms, such as wing flap screwjacks. Its consistency is between an NLGI No. 1 and No. 2 grease.

Mobilgrease 28 meets the quality level of U.S. Military Specification MIL-G-81322E, General-Purpose, Aircraft, and is approved against U.S. Military Specification DOD-G-24508A (Navy) for shipboard auxiliary machinery. It can be designated U.S. Military Symbol WTR and NATO Symbol G-395.

Mobilgrease 28 has been widely used for military and related applications, worldwide, for more than 30 years. This leading product is based on the synthesized PAO base stocks that were pioneered by the RandD arm of the company resulting in step-out performance not only in grease but in many fluid lubricants, too.

  • Mobilgrease 28 is one of many Mobil branded PAO-based products recognized around the world for innovation and outstanding performance. Synthetic products like Mobilgrease 28 represent ExxonMobil's, continuing commitment to using advanced technology to provide outstanding products. Close contacts between ExxonMobil scientists and application specialists and key equipment builders ensure that the products meet the needs of the latest aviation equipment designs.
  • Good resistance to high temperature stresses and excellent starting and low torque at low-temperature are two of the most important requirements of aviation greases.To meet this combination of needs our product formulation scientists chose proprietary synthetic base oils for Mobilgrease 28 because of their exeptional thermal/oxidative resistance potential, and superb low-temperature capability. Our formulators chose specific thickener chemistry and a prorietary additive combination which would maximize the benefits of the synthetic base oils.
  • Mobilgrease 28 meets the requirements of key military and commercial aviation specifications and has built up an excellent reputation for performance and reliability among users around the world. Mobilgrease 28 provides the following advantages and potential benefits:

  • Landing wheel assemblies
  • Control systems, screwjacks, servo devices, actuators, sealed-bearing motors and oscillating bearings
  • Helicopter rotor bearings on aircraft and on naval shipboard auxiliary machinery
  • It also can be used where superseded specifications MIL-G-81322 (WP), MIL-G-7711A, MIL-G-3545B, and MIL-G-25760A may be called for
  • Mobilgrease 28 also is recommended for industrial lubrication, including sealed or repackable ball and roller bearings wherever extreme temperature conditions, high speeds, or water washing resistance are factors. Typical industrial applications include:
  • Conveyor bearings
  • Small alternator bearings operating at temperatures near 177° C
  • High-speed miniature ball bearings, and bearing situations where oscillatory motion, vibration, and fretting create problems
