What features distinguish AVGAS from Jet fuel?

The distinguishing feature between AVGAS and Jet fuel is that AVGAS has a higher octane rating and is specifically formulated for use in piston engines. Piston engines, commonly found in smaller general aviation aircraft, require fuels that can withstand higher compression without causing pre-ignition, which is why AVGAS is designed with a higher octane rating. In contrast, Jet fuel is tailored for turbine engines, which operate differently and require a fuel that can perform well at varying altitudes and temperatures. The properties of Jet fuel support efficient operation and combustion in turbine designs, differentiating it fundamentally from AVGAS, which serves a different type of engine altogether.

The other options do not accurately define the core differences between the two types of fuel. While some AVGAS formulations may contain renewable components, this is not a general feature that distinguishes it from Jet fuel. Price differences can vary greatly based on market conditions, and flash point characteristics typically show that AVGAS has a higher flash point compared to Jet fuel, contradicting that particular statement.
