MOBIL 33 GREASE Mobilgrease 33 is a high-performance lithium-complex grease designed for general-purpose aircraft use. Its consistency is between the NLGI grades 1 and 2. Mobilgrease 33 utilizes a 100% polyalphaolefin base oil and premium additives which ensure outstanding lubrication performance over a wide temperature range and operating conditions. Mobilgrease 33 is a true multipurpose aviation grease intended for use in highly loaded anti-friction bearings, gears, and actuators as well as instruments, high speed bearings (though not recommended for wheel bearings), and general airframe lubrication, over operating temperatures from –100ºF to 250ºF (–73ºC to 121ºC). It can be used in all applications for which the aircraft manufacturer specifies U.S. Military Specification MIL-PRF-23827, Type I (Grease, Aircraft and Instrument, Gear and Actuator Screw, Grease thickened with metallic soap), Boeing BMS 3-33B (Grease, Aircraft, General Purpose), and Airbus AIMS09-06-002/SAE AMS3052 (Grease, General Purpose, Airframe, Low Temperature Range, Lithium Thickened). Mobilgrease 33 is listed in the Qualified Products List of Airbus, Boeing, and the U.S. Military for these specifications. The NATO Code Number for Mobilgrease 33 is G-354. Meets Boeing BMS 3-33 and MIL-PRF-23827. Before using Mobilgrease 33, review Boeing Service Letter BMS 3-33 General Purpose Aircraft Grease. The actual Service Letter number varies by aircraft and covers most models. These include 707-SL-20-018-B, 727-SL-20-028-B, 737-SL-20-032-B, 747-SL-20-047-B, 757-SL-20-027-B, 767-SL-20-027-B, and 777-SL-20-003-B.
