Which of the following is NOT a turbine/jet fuel type?

• A. Jet A
• B. Jet A-1
• C. Jet B
• D. AvGas 100/130

Answer: (D)

Turbine/jet fuels are kerosene-based fuels that meet strict aviation turbine fuel specifications. Jet A and Jet A-1 are standard kerosene-based fuels used in most civil jet engines, with Jet A-1 having a lower freezing point. Jet B is a kerosene/gasoline blend used in very cold conditions. AvGas 100/130, on the other hand, is aviation gasoline for piston-engine aircraft and does not meet turbine-fuel specifications. It’s formulated for spark-ignited engines and can have properties (like higher volatility and additives) that aren’t suitable for turbine fuel systems, making it inappropriate for turbine/jet engines. That’s why AvGas 100/130 is the correct choice as not being a turbine/jet fuel.
