AeroShell™ Oil W80 SAE Grade 40 Ashless Dispersant Aircraft Piston Engine Oil - Quart Bottle 80WQT, an AeroShell Oils W80 is an ash less dispersant oils specifically developed for aviation piston engines. They reap the performance benefits of combining non-metallic additives with selected high-viscosity index base oils. Additives in 80WQT leave no metallic as residues that can lead to deposit formation in combustion chamber and on spark plugs FEATURES • High stability, dispersancy and anti-foaming performance • High-viscosity index base oils help protect engine components more effectively under the high-shear stresses that an engine places on lubricants • Prevents pre-ignition and engine failures BENEFITS • Promotes engine cleanliness • Compatible with other approved aircraft piston engine oils • AeroShell W Oils are inherently stable in storage SPECIFICATIONS • Series: W80 • Container Type: Drum • Composition: 1 to 3% Alkylated Phenol Ester • Form: Liquid • Boiling point: >280°C • Flash Point: >=225°C • Flammability Limit: 1 to 10 % • Density: 0.88 lb/gal • Specific Gravity: 0.88 • Vapor density: >1 • Viscosity: 14.5 cSt • Pour/Drop Point:
