Shell Aeroshell Turbine Oil 390

Description

Product Description

AeroShell Turbine Oil 390 (ASTO 390) is a high-performance synthetic diester oil specifically designed for use in aviation turbine engines. With its carefully balanced formulation and exceptional properties, ASTO 390 ensures optimal performance, reliability, and safety for auxiliary power units (APUs), starters, and turbocompressors. Let’s delve into the details of this remarkable aviation lubricant.

Performance of AeroShell Turbine Oil 390

Reliable Cold-Soak Starting

ASTO 390 is engineered to enhance APU starting reliability, particularly during cold-soak conditions. When an aircraft’s main engine fails, confidence in the APU’s ability to start becomes crucial. The extended range twin operations (ETOPS) certification partly relies on the APU’s reliability. During cruising, APUs are typically shut down, and the oil can cool to temperatures below -40°C. Standard 5-cSt oils experience a significant viscosity increase at such low temperatures, resulting in viscous drag and potential hung starts. In contrast, ASTO 390 exhibits a much smaller viscosity increase, making it ideal for cold-soak start-up. This property maximizes ETOPS times, ensuring that the APU can efficiently compensate for any reduction in electrical power during engine failure.

Features of AeroShell Turbine Oil 390

1. Synthetic Diester Base Oil: ASTO 390 utilizes a 3-cSt synthetic diester oil as its base, providing excellent thermal and oxidation stability.
2. Additive Balance: The carefully selected and balanced combination of additives enhances load-carrying capacity and overall performance.
3. Approved Specifications: ASTO 390 meets stringent standards, including Def Stan 91-94 (British), IPM-10, VNII NP 50-1 4f and 4u (Russian analogue), and Joint Service Designation OX-7.

Benefits of AeroShell Turbine Oil 390

1. Improved Cold-Soak Reliability: ASTO 390’s viscosity characteristics minimize viscous drag during cold starts, ensuring reliable APU operation even in extreme temperatures.
2. Enhanced ETOPS Performance: By maintaining lower viscosity at cold-soak start-up temperatures, ASTO 390 contributes to maximizing ETOPS times.
3. Reduced Maintenance Downtime: Reliable APU starting reduces maintenance requirements and operational disruptions.
