You might think that all automobile fuels are the same, but they aren’t. Automobiles can run on one of three types of fuel: gasoline, diesel, and biodiesel. All of these fuels are burned inside of the engine, which creates the heat and energy that is used to power the car, but there are important differences between them. Gasoline and diesel are the most common fuels, but they are burned differently. Diesel fuel is heavier and less flammable than gasoline, so it has to be compressed before it will burn. Gasoline is lighter than diesel, but both of these fuels are made from crude oil. Biodiesel, on the other hand, is made from vegetables.
