Aeroshell W100

AeroShell Oil W100 is a mineral ashless dispersant oil for aircraft piston engines. It combines non-metallic additives with selected high viscosity index base stocks to give stability, dispersancy and anti-foaming performance. Its additives leave no metallic ash residues that can lead to deposits in combustion chambers and on spark plugs and cause pre-ignition. It promotes engine cleanliness, helps keep engines sludge free and reduce oil consumption, helps engines reach TBO and protects highly stressed parts against scuffing and wear. It is used in four-stroke certified reciprocating piston engines, including fuel-injected and turbocharged engines; it is not recommended for automotive engines.
