AeroShell Piston Engine Oil W80, W100, and W120 are all types of aviation engine oils that have been specifically designed to cater to piston engines. These oils are ashless dispersant oils, which means they are formulated to disperse any contaminants and prevent the formation of deposits on critical engine components.
These oils have to meet certain performance standards to ensure their effectiveness and safety. The SAE J-1899 standard specifies the requirements for aviation piston engine oils and has replaced the MIL-L-22851D standard. AIR 3570 is a specification for aviation piston engine oil used in military applications, while MS-20 is a specification for aviation piston engine oil used in naval aviation.
AeroShell Piston Engine Oil W80, W100, and W120 have been tested and found to meet these performance requirements, ensuring that they meet the necessary standards for use in aviation piston engines.
