AEROSHELL GREASE 6 Mineral Grease For Aircraft Oil 6, Multi-Purpose Mineral Base AeroShell Grease 6 has a temperature range of -40°C to +121°C, good load carrying ability and inexpensive, making it suitable as a general grease for reciprocating engines. AEROSHELL greases are fun for a wide variety of airline lubrication applications. Shell's counter Microgel thickener technology is used in several AEROSHELL greases to provide greases that simplify soap-type thickener testing. Microgel thickened greases also exhibit excellent load bearing ability and temperature variations have been discovered. These factors make Microgell greases particularly suitable for multi-purpose applications found in aircraft. The multi-purpose properties of many of the AEROSHELL greases allow them to lubricate less grease in utility aircraft, thus reducing the most cost and minimizing the misapplication of the wrong grease.
