Hello Milton,
Avgas 100LL is a gasoline fuel for use in reciprocating piston engined aircraft. As with all gasoline, Avgas is very volatile and is extremely flammable at normal operating temperatures. Procedures and equipment for safe handling of this product must therefore be of the highest order.

Avgas 100LL aviation fuel has an octane rating of 100 and the LL stands for ‘low lead’. The octane rating ensures satisfactory combustion qualities defined as the anti-knock rating. The other properties are the distillation range and volatility which are important for mixture distribution and cold starting. Other specification items are included to ensure that the fuel has good storage life, will not corrode engines or fuel system components and can be satisfactorily supplied to the engine under all operating conditions.
However, [font=Inter, sans-serif] Jet A-1[/font] ( Aviation turbine fuels) are used for powering jet engines, turbo-prop engines and more recently diesel piston engines in aircraft.
I hope this will be helpful to you
