Ashless Dispersant (AD) Engine Oil AeroShell W80 is a premium, ashless dispersant (AD) aviation piston engine oil. Formulated by combining non-metallic additives with selected high-viscosity index base stocks, it provides exceptional stability, dispersancy, and anti-foaming performance. Unlike straight mineral oils, this advanced formulation keeps engines cleaner by suspending dirt and wear particles, preventing sludge build-up. MFG Part Numbers: • Quart (Case of 6): 550050834 • 55-Gallon Drum: 550041183 Key Features & Benefits Ashless Dispersant: Keeps engines clean by minimizing sludge and suspending deposits for safe removal during routine oil changes. High Viscosity Index: Maintains excellent viscosity and consistent protection across a wide range of operating temperatures. Low Pour Point: Ensures free-flowing lubrication in cold weather, allowing for easier engine starts and immediate component protection. Extended Engine Life: Superior anti-wear properties help reduce friction and protect critical engine parts from premature wear. Applications AeroShell W80 is highly recommended for use in a wide variety of four-stroke cycle, certified aircraft reciprocating piston engines, including those manufactured by Lycoming, Continental, Teledyne, Pratt & Whitney, and Rotax.
