Kerosene is quite commonly by used in aircraft gas turbines. It is not as volatile as gasoline and, therefore, there is less possibility of vapour lock and fuel loss. But its combustion efficiency is low compared to gasoline.

The lubrication properties of gasoline are poorer. About 5 to 20% of a barrel of crude may be refined kerosene whereas 40 to 50% of a barrel of crude oil may be refined into gasoline which shows that gasoline can be available in large quantities.
