Cappa and his colleagues said the amount of petroleum in fuel is far greater — about 15 times more by weight — than lotions, paints and other household products. But the fuels used in cars are much cleaner than they used to be, meaning fewer smog-producing pollutants waft into the air in the exhaust.
