AeroShell W Piston Engine Oils were the first non-ash dispersant oils to be used in aircraft piston engines.

AeroShell Piston Engine Oil combine 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.

Features:

• Promote engine cleanliness
• Help keep engines sludge free
• Help reduce oil consumption
• Help engines reach TBO (Time Between Overhaul)
• Protect highly stressed engine parts against scuffing and wear
• Aviation Oil
• Mineral Oil
