Mobil 28 gun grease in easy-to-use quarter ounce container re-packaged by Pilots HQ. Why buy a whole tube for nearly thirty bucks when you do not need that much? This synthetic grease with clay thickener, often used on aircraft wheel bearings can withstand high temperatures (-65F to 350F) and will make your trigger and gun operate very smoothly, reducing friction, wear and even corrosion. Mobilgrease 28 synthetic grease is the same grease used by Geissele Triggers, Ruger, as well as many others. 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 300C, which provides excellent stability at high temperatures. Mobil grease 28 resists water washing, provides superior load-carrying ability, reduces frictional drag, and prevents excessive wear. Tests show that Mobil grease 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.
