Most liquid fuels in widespread use are derived from the fossilized remains of dead plants and animals by exposure to heat and pressure in the Earth's crust. However, there are several types, such as hydrogen fuel (for automotive uses), ethanol, jet fuel and biodiesel which are all categorized as a liquid fuel.
Gas stations in the US offer many types. There is regular unleaded, super unleaded, and high test gasoline. These are different due to the octane rating of each. Most stationsâ¦ offer diesel fuel and some offer bio-fuel (made from corn or other plants). Some offer a mixture of gas and ethanol which comes from corn.
