AeroShell Oils and AeroShell W Oil is intended for use in four-stroke cycle aircraft reciprocating piston engines. The term “ashless dispersant” was given to aviation oils to distinguish them from straight mineral aircraft piston engine oils. Because of the negative effect of ash on aircraft engine performance, it is very important that ash-containing oils are NOT used in an aircraft piston engine.

Shell's collaboration with turbine engine manufacturers has led to the development of a complete range of turbine engine oils, from mineral oil formulations through to leading edge, fully synthetic hindered esters. AeroShell Turbine Oils have demonstrated their flexibility for use both inside and outside today's hostile turbine engine environment.

Shell Aviation can offer a range of aviation greases designed to fill almost every lubrication need of the aviation community.
