AEROSHELL PISTON ENGINE OIL W80

Description

AeroShell Oil W80 is an SAE 40 ashless-dispersant mineral oil formulated for approved four-stroke aircraft piston engines. It controls sludge, varnish and piston deposits while protecting internal components against wear, oxidation and corrosion. Its SAE 40 viscosity provides faster cold circulation than heavier monogrades, making it particularly suitable for cooler ambient operating conditions. The oil keeps contaminants suspended until removal during scheduled oil changes and supports engine cleanliness during regular service. It is intended for engines that have completed running-in and meets SAE J1899 Grade SAE 40 requirements.
