Top AeroShell Lubricants for Aircraft Performance in FY2026: Grease 33, Grease 22, and Engine Oils

Aircraft lubricants form the backbone of a reliable aircraft, with systems and subsystems depending on them to function properly, and prolong their operational cycles and time between failure and overhaul. 

AeroShell lubricants are engineered to reduce friction and wear on bearings, engines, and other critical components. Whether you are working with turbine engines, piston engines, or airframe structures, AeroShell has a lubricant for you. 

Choosing the right lubricants and early-year stocking help reduce downtime, extend component lifespans, and support overall aircraft maintenance during FY2026 operations and beyond. Let’s take a look at the top 5 AeroShell products you need to stock up on now for the year to come!

Aviation Greases and Oils: Built for Demanding Environments

Aircraft grease and aviation oils are formulated for high speeds, heavy loads, and extreme conditions. After all, if you think that heavy diesel equipment or automobiles are hard on greases and lubricants, aircraft are much harder. 

AeroShell products are built to withstand thermal stress, heavy loads, and extreme conditions commonly encountered in the everyday operation of aircraft. AeroShell greases are made for landing gear, wheel bearings, airframe lubrication, and anything else that requires grease across the aircraft

Synthetic vs. Clay-Based Greases in Aircraft Applications

Different parts of the aircraft require different greases based on load, movement, operating temperature, and environment. Clay-based greases such as AeroShell Grease 22 use a synthetic hydrocarbon oil and clay thickener to provide load-carrying capacity, corrosion resistance, and water washout resistance. 

With a temperature range of -54°C to +177°C, AeroShell 22 is used for general airframe lubrication, wheel bearings, landing gear, actuators, screw-jacks, engine accessories, electric motors, and other critical aircraft components that operate under high-speed and high-load conditions.

Synthetic greases such as AeroShell Grease 33 are designed for extreme environments and broader fleet standardization. Lithium complex thickened and approved to BMS 3-33C and MIL-PRF-23827C AeroShell Grease 33 provides thermal stability, reduced wear, and corrosion protection across a temperature range of -73°C to +121°C. Stock both greases and your maintenance team can protect airframes, bearings, actuators, and electronic components, minimize downtime, improve reliability, and maintain optimal aircraft performance.

Why AeroShell Grease 33 Is a Priority Stock Item

AeroShell Grease 33 is a high-performance synthetic aircraft grease designed to protect critical aircraft components under high loads, high speeds, and extreme environments. With a lithium complex thickener and synthetic hydrocarbon/ester base oil, it provides excellent corrosion protection, water washout resistance, and long life with high thermal stability. 

AeroShell Grease 33 operates over the temperature range -73°C to +121°C and is suitable for demanding aviation applications. Approved to key military and aerospace specifications BMS 3-33C and MIL-PRF-23827C, it is used for landing gear, bearings, actuators, engine accessories, and electronic components on commercial and military aircraft. 

Its broad coverage helps maintenance teams reduce grease inventories, eliminate product misapplication, and improve reliability. Stock AeroShell Grease 33 in FY26 to avoid supply disruption during peak aircraft maintenance and ensure optimal performance and protection of critical components.

Supporting Maintenance with AeroShell 22 Airframe Grease

AeroShell Grease 22 is a general-purpose aircraft grease used across commercial and military aircraft for routine maintenance and airframe lubrication. With a synthetic hydrocarbon base oil and clay thickener, it provides balanced protection against wear, corrosion, and rust, with strong load-carrying and water-washout resistance.

AeroShell 22 operates from -54°C to +177°C, so it is perfectly suited for winter and early spring conditions. Common applications include wheel-bearing grease points, landing gear, actuator screw mechanisms, control systems, screw jacks, engine accessories, electric motors, hinge pins, and general airframe lubrication surfaces. 

Approved to MIL-PRF-81322G and other global military specs, AeroShell Grease 22 has proven reliability in harsh aviation environments. Cartridge packaging makes line maintenance and quick servicing easy, so stock up ahead of scheduled maintenance cycles when cold-weather operations and inspection workloads are at their peak.

Turbine and Piston Engine Oils: Completing the Lubrication Plan

AeroShell turbine oils, including AeroShell Turbine Oil 560 and AeroShell Turbine Oil 555, are designed for high-speed turbine engines in extreme environments and wide temperature ranges. AeroShell 560 is a high-thermal-stability synthetic ester oil approved to MIL-PRF-23699 HTS and SAE AS5780 with excellent coking, oxidation, and wear resistance during cold-weather starts and sustained high-temperature operation.

AeroShell 555 has similar 5-centistoke performance with strong load-carrying capability and corrosion protection for turbine engines, helicopter transmissions, and gearboxes.

For piston-powered aircraft, AeroShell W80 supports cooler ambient operations by maintaining oil film strength, reducing engine wear, and promoting engine cleanliness without ash deposits W80. Stock your aviation oils alongside aircraft grease, and you’ll have complete lubrication coverage for engines, accessories, and critical components throughout the fiscal quarter or year.
