Aviation Spirit (also known as AVGAS) is a type of motor fuel specifically designed for use in aircraft, especially in older piston-engine aircraft.

  • Boiling Point: Aviation spirit typically has a low initial boiling point, which helps ensure that the fuel vaporizes easily for combustion in aircraft engines.
  • Octane Rating: The octane rating of aviation spirit ranges from 73 to 120/130. This high octane rating is crucial for preventing engine knock and ensuring efficient engine performance, particularly in high-performance and high-compression engines.
  • Specifications: Aviation spirit must meet specific standards and specifications to ensure it provides reliable performance and safety in aviation applications.

This type of fuel is critical for maintaining the proper operation of aircraft engines, particularly those in older or specialized aircraft that are designed to use high-octane fuel.
