Question

Why is kerosene not used in cars?

Answer 1

The primary reason is gasoline is more efficient. It vaporizes easily (below boiling point of water), burns faster and more completely. On top of that, it is cleaner burning than kerosene.

Kerosene is closer to diesel fuel and is less refined. It can withstand higher temperatures before it vaporizes. This means combustion is not as easy as it is with gasoline. Therefore kerosene is not used a fuel for automobiles
