Shell Aviation can offer a range of aviation greases designed to fill almost every lubrication need of the aviation community. There follows very brief descriptions of the major products in the AeroShell Grease range.
Frequent oil changes specified by engine hour time limits and
calendar time limits are necessary and not caused by the oil
wearing out but by the by-products contaminating the oils such
as: water, dust, dirt and unburned fuel. Operators are urged to
follow the engine manufacturers’ or rebuilders’ recommendation
for oil change intervals to avoid the damaging lead sludge found
in engines that can shorten engine life and possibly void
warranty work by the engine manufacturer.
