Gasoline, also known as petrol, is a transparent, petroleum-derived flammable liquid used as fuel for internal combustion engines. Distinguished by its octane rating (e.g., 91, 95, 98), which indicates its resistance to premature combustion, gasoline is engineered to deliver powerful and efficient performance in spark-ignition engines. It is the most common fuel for passenger cars, motorcycles, and light-duty trucks, providing the high energy content required for modern transportation.
