AeroShell W 120 were the first non-ash dispersant oils to be used in aircraft piston engines. They combine non-metallic additives with selected high viscosity index base stocks to give exceptional stability and anti-foaming performance.  These additives leave no metallic ash residues that can lead to deposit formation in combustion chambers and on spark plugs, which can cause pre-ignition and possible engine failure. 

Applications 

Intended for use in four-stroke (four-cycle) certified reciprocating piston engines, including fuel injected and turbo charged engines. 

Performance, Features & Benefits 

Promotes engine cleanliness, helps keep engines sludge free, helps reduce oil consumption, helps engines reach Time Between Overhaul, protects highly stressed engine parts against scuffing and wear.
