AeroShell Grease 6

AeroShell Grease 6 is a general-purpose aviation grease formulated from a mineral base oil and clay thickener. It provides reliable lubrication and corrosion protection for airframe bearings, gearboxes, and other aircraft components operating within a moderate temperature range.

This grease combines stability, corrosion resistance, and affordability, making it ideal for a wide variety of maintenance tasks. It offers good water resistance, low noise characteristics, and consistent performance across a temperature range of -40°C to 121°C.

AeroShell Grease 6 is widely used for airframe lubrication, antifriction bearings, plain bearings, and gearboxes. It’s suitable for aircraft from major manufacturers such as Cessna and Piper, where dependable, all-around grease performance is required.

It functions effectively between -40°F and 250°F (-40°C to 121°C). While excellent for general aviation use, aircraft operating in very low temperatures may benefit from a grease with a broader cold-weather range, such as AeroShell Grease 7 or 33.

AeroShell Grease 6 can handle moderate loads but is not designed for heavy-duty or high-load components, such as wheel bearings. In such cases, AeroShell Grease 22 or 33 – both engineered with advanced load-bearing additives – are preferred alternatives.

It uses a clay thickener combined with a mineral base oil, providing excellent shear stability and resistance to melting at high temperatures. This combination ensures consistent lubrication and performance throughout its operational range.

Yes. The grease contains oxidation inhibitors and corrosion protection additives, which help prevent rust formation and degradation of metal surfaces under humid or high-stress conditions.

It demonstrates excellent water resistance, with a water washout rate of only 3% at 38°C, ensuring it remains in place even during exposure to rain, humidity, or washing procedures.

Yes. It meets the MIL-PRF-24139B specification and complies with older standards, including MIL-G-7711A and DCSEA 382/A. It is also designated under NATO Code G-382, confirming its global acceptance for aviation use.

Although possible, AeroShell Grease 6 may be too thick for delicate instruments requiring fine-tolerance lubrication. Lighter greases specifically formulated for instrument bearings are typically more suitable.

Lubrication intervals depend on the aircraft model and operational environment. Always follow the specific recommendations in the aircraft’s maintenance manual to ensure proper performance and component protection.

Mixing AeroShell Grease 6 with greases of different base oils or thickeners is not recommended, as incompatibility can lead to softening, oil separation, or reduced protection. Always clean old grease thoroughly before switching to a new one.

Yes. Thanks to its stable mineral oil base and general-purpose properties, it’s occasionally used in compatible industrial and automotive applications requiring moderate temperature and load handling.

It presents no significant health risks when handled correctly. Use gloves to avoid skin contact. Wash thoroughly with soap and water after handling. Always dispose of used grease through authorized collection points to protect the environment.
