12 quart case. AeroShell Oils W80, W100 and W120 are ash-less dispersant oils specifically developed for aviation piston engines. They combine non-metallic additives with selected high viscosity 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, which equates to AeroShell Oil W80, W100 and W120 respectively.
- Promotes Engine Cleanness. The non-ash forming, polymeric additive was developed to help eliminate the harmful combustion chamber deposits that occur during normal operation.
- High Viscosity Index Base Oils used in AeroShell W oils maintain their viscosity and help protect engine components more effectively under the high shear stresses that an engine places on lubricants.
- Provides Compatibility with other approved aircraft piston engine oils. Since AeroShell Oils W80, W100 and W120 are fully approved to SAE J-1899 and are listed on the relevant Qualified Products List (QPL), elaborate precautions are not needed when changing from similarly approved aircraft engine oils, as long as these oils are qualified products.
- AeroShell W Oils are inherently stable in storage. Providing that they have been stored and handled correctly, prolonged storage does not have any effect on their quality, properties or performance.
