About This Product
AeroShell W Oils were the first non-ash dispersant oils to be used in aircraft piston engines. They combine nonmetallic additives 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.
