About AeroShell Grease 33
Of 359 grease application points on a Boeing 737, AeroShell Grease 33 lubricates all but 9 of them
Historically, aircraft maintenance operations had to carry several greases for different lubrication needs. But then Shell developed AeroShell Grease 33 (ASG33) – a universal airframe grease. ASG33 is effective on virtually all airframe components. For those components where ASG33 is not suitable, AeroShell Grease 22 will do the job. A complete grease range in two products.
AeroShell Grease 33 provides all-round protection in the harshest of conditions, from temperatures as low as -54°C through to scorching heat. All the while, AeroShell Grease 33 helps maintain mechanical stability, avoids water washout and protects your aircraft parts from corrosion caused by de-icing fluids. It often exceeds industry requirements and outperforms many AeroShell Grease 33 alternatives in laboratory tests – making it a trustworthy choice for facing the extreme conditions your aircraft will face.
Why use AeroShell Grease 33?
Quite simply, AeroShell Grease 33 sets the standard. That’s why some of aviation’s biggest manufacturers – including Airbus, Boeing and Comac – choose to use it. If it’s good enough for businesses with a strong reputation for excellence, you know you can trust our product and pricing.
Here are a few more reasons to choose AeroShell Grease 33:
- Replacing the number of greases used on the aircraft with a common grease lessens the likelihood of misapplication of the wrong grease and damage to the aircraft;
- The much-improved corrosion resistance and wear protection properties of ASG33 help prevent expensive replacement of parts by extending maintenance life while also allowing lubrication intervals to be extended; and
- Replacing a range of greases with just one reduces stock inventory and costs.

We put AeroShell Grease 33 through industry-standard tests, proving it offers the best overall protection in real-world scenarios compared to other AeroShell Grease 33 alternatives. Here’s how it did on the tests:
Mechanical stability
Through a roll stability test, the penetration resistance of each grease was assessed before and after testing to determine their level of stability. AeroShell Grease 33 recorded the smallest penetration difference, proving its reliability and stability critical to withstand high shear load and retain its consistency over a longer period.
Rust and wear resistance, copper corrosion, and fretting protection
After a rust and corrosion prevention test, the performance of AeroShell Grease 33 showed no visible corrosion compared to our competitors. This proves the ability of ASG33 to provide enhanced protection for your components, especially in combating runway de-icers.
It also performed excellently when tested on its ability to reduce damage and corrosion caused by contact between metal components.
It also performed excellently when tested on its ability to reduce damage and corrosion caused by contact between metal components.
Water resistance
Through a water washout test, the water resistance of each grease was assessed. AeroShell Grease 33 recorded the lowest percentage of weight lost, showing performance nearly twice as that of our competitors, which is important to ensure the grease stays in place in wet conditions and protects your aircraft
When tested on its performance in different temperatures, AeroShell Grease 33 was uncompromising in high temperatures and in temperatures as low as -73°C.
For further guidance on product health and safety refer to the appropriate Safety Data Sheet.
History of AeroShell Grease 33
Aircraft operators have been looking to reduce the number of greases needed in their inventories for years, which is why Boeing began researching a new, general purpose, corrosion-inhibiting grease and introduced the new specification BMS 3-33.
This new specification was intended for a grease that offered improved performance and could be used in the widest possible range of grease applications, considering factors like operating temperatures, loads, and other environmental conditions.
Shell worked closely with Boeing as it developed BMS 3-33, and created AeroShell Grease 33 – the first, and for some years only, grease approved to this specification.
How to use AeroShell Grease 33
AeroShell Grease 33 can be used for routine lubrication in the following instances:
- Boeing aircraft where MIL-PRF-23827C is specified and where the obsolete BMS 3-24 is specified.
- In applications where MIL-PRF-23827C and BMS 3-33C are specified on aircraft manufactured by McDonnell Douglas, Airbus, BAe Regional Aircraft, Canadair, Lockheed, Embraer, Fokker and Gulfstream (except for wheel bearings, applications above 121°C (250°F) and sliding applications requiring molybdenum disulphide).
Other aircraft manufacturers, such as Canadair, Saab, and Lockheed are evaluating AeroShell Grease 33 with the aim of approving it for use on their aircraft. Operators should regularly check with these manufacturers for the latest status.
Typical properties of AeroShell Grease 33
Here are some of the typical properties of AeroShell Grease 33 and how it compares with the requirements for the BMS 3-33C, AIMS 09-06-002, and SA AMS 3052 specifications. Discover more by reading the AeroShell Book .
- Oil type – Synthetic Hydrocarbon/Ester.
- Thickener type – Lithium Complex.
- Useful operating temperature range – -73°C to +121°C.
- Water resistance test loss at 79°C – <6%m.
- Anti-friction bearing performance at 121°C – 1,200+ hours.
- Copper corrosion over 24 hours at 100°C – Passes the test for the BMS 3-33C, AIMS 09-06-002, and SA AMS 3052 specifications .
- Colour – Green.
