Shell offers a complete line of eight aviation greases designed to fill almost every lubrication need of the aviation community. The product line consists of eight products each designed for specific applications. Six of the Shell aviation greases are based on Microgel®, an inorganic thickening agent. The seventh grease is soap type grease specifically designed to provide the unique lubricant requirements of helicopter main and tail rotor bearings. The eighth grease is thickened with lithium complex soap and is approved against both Boeing and military specifications.

AeroShell Grease 7 is low temperature multipurpose aviation grease recommended for instruments and general airframe lubrication of turbine powered aircraft as well as highly loaded gears and actuator screw mechanisms. It is made with synthetic diester base oil and a Microgel® non-melting inorganic thickener, which provides a useful temperature range of -100° F (-73° C), to +300° F (+149° C). AeroShell Grease 7 is qualified under the MIL-PRF-23827C specification.
Applications:
Aerospace; Mil-Spec or Military; Turbine Powered Aircraft
Whenever an aircraft is certified, all of the lubricants are specified for each application point on the type certificate. The type certificate will specify, either by military specification number or by specific product names, those products, which are qualified to be used. The FAA regulations state that only products qualified for specific applications can be used in certified aircraft. Therefore, in aviation it is the responsibility of the aircraft owner or designated representative to determine which products should be used. Lubricant recommendation charts for specific aircraft should be consulted, or the original airframe manufacturer should be contacted for specific product recommendations.
