Just thought I would add this for those who don't keep up with Aviation Stuff.
Piston engine aircraft (The Cessnas, Pipers, the Beech Bonanzas, etc) use 100LL. (AvGas)
The next class (UP) of aircraft are
Turbo Props. These are aircraft that have "Turbine" engines.....BUT: with a reduction gearbox, and a conventional propeller. They use Jet Fuel. (Kerosene).
The TOP class of aircraft are the JETS. Lear jets, Citations, Jet Streams, and ...Boeing 737s..and beyond. They use Jet Fuel..(Kerosene).
NB
PS: I Totally LOVE this Technical stuff.
