Aeroshell 33 Aviation Grease

AeroShell Grease 33 is a synthetic, lithium-complex aviation grease developed as a multi-purpose airframe lubricant for commercial and military aircraft. It combines a wide operating temperature range with strong corrosion protection, water resistance, load-carrying capability, and mechanical stability.

AeroShell Grease 33 operates effectively from -73°C to +121°C (-99°F to +250°F) and is qualified to MIL-PRF-23827C Type I. It is also approved to major aviation specifications including Boeing BMS 3-33C, SAE AMS3052, and Airbus AIMS 09-06-002.

AeroShell Grease 33 Applications

AeroShell Grease 33 was developed as a multi-purpose airframe grease to help reduce the number of different greases required for routine aircraft lubrication. Its broad performance characteristics allow it to be used across a wide range of airframe lubrication applications where the applicable aircraft or component manufacturer specifies a compatible grease.

Shell identifies AeroShell Grease 33 for routine lubrication on aircraft manufactured by Airbus, Boeing, Embraer, Fokker, Gulfstream and other aircraft manufacturers, subject to the specific application limitations and maintenance documentation. Shell specifically excludes wheel bearings, applications above 121°C, and sliding applications requiring molybdenum disulphide.

Typical applications include:

• Airframe lubrication
• Bearings and bushings
• Actuators and screw mechanisms
• Control systems
• Hinge points and mechanisms
• General aircraft lubrication points
• Other applications where MIL-PRF-23827C Type I or an applicable OEM specification is required

AeroShell Grease 33 Specifications

Universal Airframe Grease

AeroShell Grease 33 was developed to provide a single, high-performance grease capable of covering a broad range of routine aircraft lubrication requirements. Its combination of synthetic base oil, lithium-complex thickener, corrosion inhibition, load-carrying capability, and wide temperature range makes it a versatile choice for airframe maintenance.

Shell's current product information describes AeroShell Grease 33 as a universal airframe grease for commercial and military aircraft. Its mechanical stability helps the grease remain in place under demanding service conditions, while its resistance to water washout provides additional protection in wet operating environments.

AeroShell Grease 33 vs. Other AeroShell Greases

AeroShell Grease 33 occupies an important position in the AeroShell grease lineup because it is designed as a broad-use airframe grease rather than a specialized grease for a single application.

For example, AeroShell Grease 64 shares the lithium-complex technology of Grease 33 but adds 5% molybdenum disulphide for extreme-pressure applications. Shell specifically positions Grease 64 for highly loaded, sliding airframe applications where additional EP protection is required.

Grease 33 should therefore be selected based on the aircraft or component manufacturer's specified application rather than simply substituted for Grease 64 or another specialized grease.

AeroShell Grease 33 for Aircraft Maintenance

For aircraft maintenance and MRO facilities, AeroShell Grease 33 can simplify grease inventory by covering a wide range of routine airframe lubrication requirements. Its approval to major OEM and industry specifications also makes it a commonly specified grease for commercial and military aircraft maintenance.

Important: AeroShell Grease 33 is not intended for every aircraft lubrication application. Shell specifically identifies limitations including wheel bearings, applications above 121°C, and sliding applications requiring molybdenum disulphide. Always verify the required grease specification and application against the current aircraft or component manufacturer's maintenance documentation.

Frequently Asked Questions

What is AeroShell Grease 33 used for?

AeroShell Grease 33 is a multi-purpose airframe grease used for a broad range of routine aircraft lubrication applications where the applicable maintenance documentation specifies a compatible grease.

What specification does AeroShell Grease 33 meet?

AeroShell Grease 33 meets MIL-PRF-23827C Type I and is also approved to specifications including Boeing BMS 3-33C, SAE AMS3052, and Airbus AIMS 09-06-002.

What is the temperature range of AeroShell Grease 33?

AeroShell Grease 33 has a useful operating temperature range of -73°C to +121°C (-99°F to +250°F).

Is AeroShell Grease 33 synthetic?

Yes. AeroShell Grease 33 uses a synthetic base oil with a lithium-complex thickener.

What type of thickener does AeroShell Grease 33 use?

AeroShell Grease 33 uses a lithium-complex thickener.

Is AeroShell Grease 33 the same as AeroShell Grease 64?

No. AeroShell Grease 64 is based on the same lithium-complex technology as Grease 33 but is fortified with 5% molybdenum disulphide (MoS₂) for additional extreme-pressure performance.

Can AeroShell Grease 33 be used in wheel bearings?

Shell specifically excludes wheel bearings from the applications for AeroShell Grease 33. Use the grease specified by the applicable aircraft or component manufacturer for wheel-bearing applications.

Can AeroShell Grease 33 be mixed with other aviation greases?

Grease compatibility should be verified before mixing products. Do not assume that two aviation greases are compatible based solely on their intended applications. Follow the applicable aircraft or component manufacturer's lubrication instructions and the grease manufacturer's compatibility guidance.
