Gasoline is a type of fuel commonly used in vehicles with internal combustion engines. It is a liquid mixture of hydrocarbons derived from crude oil through a process called fractional distillation. Gasoline is highly flammable and is typically stored in underground tanks at gas stations. It is pumped into vehicles through a nozzle and is ignited by a spark plug to power the engine. Gasoline is a vital component of modern transportation and is essential for powering cars, trucks, motorcycles, and other vehicles. It is available in different grades, with higher octane ratings providing better performance for high-performance engines.
