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: ＜=-22°C • Grade: 40 • Suitable for Use With: Aircraft Piston Engine • Domestic​/​Import: Import TECHNICAL INFORMATION • SAE J1899 Grade 40 • O-123 NATO • OMD-160 Joint Service Designation • Textron Lycoming 301F • Teledyne Continental MHS 24B • Pratt & Whitney Service Bulletin 1183-S • Curtiss Wright Various Service Bulletins • Franklin Engines Various Service Bulletins Aeroshell 80W 80W-1QT 80W-QT 80W QT
