Crude oil may contain hundreds of different types of hydrocarbons. some examples include:
butane(c4h10)
dodecane (c12h26)
octane (c8h18)
benzene (c6h6)

many common fuels, such as gasoline and kerosene, are combinations of these substances or others. when these fuels burn, they combine with oxygen (o2) to produce carbon dioxide (co2) and water (h2o).
