With a 10-year shelf life – offering more than three times the life of similar-type competitive greases – Mobilgrease 33 grease helps our partners optimize their shelf-life management programs, enabling potential cost savings.
Mobilgrease 33 is a high-performance, BMS3-33 multipurpose airframe grease uniquely formulated with a proprietary blend of polyalphaolefin (PAO) base oils and lithium complex soap. Unlike other commercially available BMS3-33 greases, this unique formulation is ester-free, providing superior performance and hydrolytic stability, excellent resistance to thermal and oxidative degradation and exceptional wear protection in heavy loaded pressure environments without an offensive odor. Our ester-free blend offers exceptional performance in wet environments to resist water washout and evaporation loss, protecting the grease from the deteriorating effects of hydrolysis.
Common grease point applications
- Outboard and inboard flaps
- Outboard and inboard slats
- Ground/flight spoilers
- Elevators and stabilizers
- Landing gear bushings
- Rudders
- Ailerons
Features and Benefits
The lithium complex thickener system provides excellent structural stability and resistance to water wash-out. Polyalphaolefin base oil is used in Mobilgrease 33 because of its exceptional thermal/oxidative resistance potential, low volatility, and superb low-temperature capability, without the potential vulnerability of an ester base oil to degradation from reaction with water. The synthetic polyalphaolefin base oil offers excellent low-temperature mobility/pumpability and very low starting and running torque values. In addition, the state-of-the art additive system in Mobilgrease 33 provides superior rust and wear protection and load-carrying capacity compared to aviation greases that meet the minimum requirements of the MIL-PRF-23827 specification.
Mobilgrease 33, with its unique features, provides the following advantages and potential benefits:

Applications
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.
