AeroShell Turbine Oil 390 is a 3 mm²/s synthetic diester oil helps to improve auxiliary power unit (APU) starting reliability, particularly cold-soak starting.
Features and benefits
Reliable Cold-Soak Starting
Significantly lower viscosity at cold-soak start-up temperatures (–40°C) than a standard 5-cSt oil, reducing viscous drag at low temperatures.
Supports ETOPS¹ operations
Enhances APU starting reliability in extreme cold conditions, and thus maximise ETOPS times.
Lower APU maintenance costs
Lower maintenance costs from reduced component wear during APU start up.
