Do cars use fossil fuels? What kind?
Yes, oil primarily.
Oil is shipped to refineries where it is broken into a number of products including gasoline, kerosene, diesel and aviation fuel (to name just a few). These oil-based fuels are what keeps the world moving for the most part. Some natural gas and propane is used in cars too, but this tends to be a small amount. Electric vehicles and hybrid electric/gasoline motor cars are starting to become more popular with consumers. Also, some cars and trucks are starting to use biofuels = those made from plant material.
