Features & Benefits of Mobilgrease 33 13.4-oz cartridges

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:

FeaturesAdvantages and Potential Benefits
High viscosity index polyalphaolefin basestockVery wide operating temperature range – outstanding high and low temperature performance.
Excellent lubricant film protection at high temperatures
Good storage stabilityGrease structure integrity maintained – low oil separation
Exceptional resistance to thermal and oxidative degradationLong grease and lubricated part service life
Resistance to degradation by water (hydrolysis)No risk of corrosion induced by acidic base oil degradation products
Low volatilityLittle vulnerability to significant base oil loss by evaporation in service
Excellent protection against wear, corrosion, and rustingExcellent bearing and component protection
Extreme-pressure characteristicsPrevention of excessive wear, even under shock load
High resistance to water washoutExcellent grease performance in adverse weather and other water-exposure conditions

Applications of Mobilgrease 33 13.4-oz cartridges

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.
