Product Information

Aeroshell Oil W80 is an ashless dispersant oil specifically developed for aviation piston engines. It combines non metallic additives with high viscosity index base oils to give exceptional stability, discrepancy 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.
