Mobilgrease 28 is a superior performance wide temperature antiwear grease designed to combine the unique properties of a polyalphaolefin (PAO) synthetic base fluid with an organo clay (non-soap) thickener. Its consistency is an NLGI No. 1 and No. It is between 2 greases. It offers outstanding performance over a wide temperature range. The paraffin-free nature of the synthetic base fluid provides excellent low temperature pumpability, very low starting and running torque, combined with a high viscosity index compared to mineral oils, and can help reduce operating temperatures in the load zone of rolling bearings.

The clay thickener gives Mobilgrease 28 a high dropping point value around 300ºC, which provides excellent stability at high temperatures. Mobilgrease 28 is resistant to water washing, provides superior load carrying ability, reduces friction resistance and prevents excessive wear. Tests show that Mobilgrease 28 effectively lubricates rolling bearings under high speed and temperature conditions. Mobilgrease 28 has also demonstrated an excellent ability to lubricate heavily loaded slip mechanisms such as vane screw jacks.

Mobilgrease 28 meets the requirements of key military and commercial aviation specifications and has built an excellent reputation for performance and reliability among users worldwide.
