  1. Combustion powers both types of engines.
  2. Oil is the source of both of these types of fuel.
  3. Gasoline is derived from the C7 – C11 range, while kerosene is derived from the C12 – C15 range (where ‘C’ is a carbon atom).
  4. Safety. Kerosene has a higher flash point than gasoline, meaning it requires a higher temperature for it to ignite. Kerosene also stays in a liquid form at lower temperatures than gasoline.
  5. Additives are put into jet fuel to prevent static buildup, an anticorrosive agent is added to prevent corrosion, a deicing agent is added to prevent fuel icing and even an antimicrobial agent is added to prevent bacteria and fungus growing and clogging the engine.
  6. It’s more similar to diesel.
