AeroShell W Oils were the first non-ash dispersant oils to be used in aircraft piston engines. They combine non-metallic addititves with selected high viscosity index base stocks to give exceptional stability, dispersancy 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. Product Features:Promotes engine cleanlinessHelps keep engines sludge freeHelps reduce oil consumptionHelps engines reach TBO (Time Between Overhaul)Protects highly stressed engine parts against scuffing and wear
