Aeroshell W100 Engine Oil
This AeroShell Oil is an ashless dispersant oil specifically for aviation piston engines. It combines non-metallic additives with selected index base oils to give exceptional stability, dispersancy and anti-foaming performance. No general rule exists for every engine type when choosing the correct grade of oil; however, based on the average ambient outside temperature at engine start-up the most common grades are SAE 40, SAE 50 and SAE 60. It equates to AeroShell Oil W80, W120 respectively.
AeroShell W80 for cold climate regions (-17 – 21°C), AeroShell Oil for temperate regions (15 – 30°C) and AeroShell Oil W120 for warmer climates (above 26°C).
