AeroShell™ Oil W120 SAE Grade 60 Ashless Dispersant Aircraft Oil - 5 Liter Jug

AeroShell W120 Oil is the first non-ash dispersant single grade oil to be used in aircraft radial piston engines. It combines non-metallic 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.

It is fully approved for SAE J-1899 (formerly MIL-L-22851D).
