Aeroshell Piston Engine Oil W120 - 3 x 5 Litre Carton - AUD 11.71 per Litre

AeroShell Oils W80, W100, and W120 are ashless 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. 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, which equate to AeroShell Oil W80, W100, and W120 respectively.

Traditionally, the choice is associated with climatic zones: AeroShell W80 for cold climate regions (-17 to 21°C), AeroShell Oil W100 for temperate regions (16 to 32°C), and AeroShell Oil W120 for warmer climates (above 26°C)

AeroShell Oils W80, W100, and W120 are produced to meet fully the SAE specification J1899 (Grades SAE 40, 50, and 60 respectively).
