AeroShell Piston Engine Oil W100 1 Qt 100WQT

AeroShell Piston Engine Oil W100 1 Qt 100WQT is a high-performance, ashless dispersant single-grade SAE 50 mineral lubricating oil engineered specifically for certified four-stroke aircraft piston engines—including fuel-injected and turbocharged models—operating in moderate ambient climates of approximately 15 °C to 32 °C. It employs a premium viscosity-index base oil paired with advanced dispersant and anti-wear additives to maintain film strength, prevent scuffing and wear of highly stressed components, resist deposit formation in combustion chambers and crankcases, and retain stability across the operating temperature range. Fully compliant with SAE J1899 Grade 50 and approved across multiple OEM service instructions, it is compatible with approved oils of similar type and supports longer time-between-overhaul (TBO) intervals by promoting engine cleanliness and performance reliability in commercial, general aviation and turbocharged engine applications.
