What kind of fuel do cars run on?

The most common fuel used by cars is gasoline, also known as petrol. Gasoline is a mixture of hydrocarbons derived from crude oil. Diesel fuel is another type of fuel used by some cars, especially those with a diesel engine. Diesel fuel is also derived from crude oil but is heavier and less flammable than gasoline. Some cars can also run on alternative fuels, such as ethanol or biodiesel, which are made from plants. Electric vehicles, on the other hand, do not use fuel but rely on electricity stored in batteries to power their electric motors.
