Why is gasoline adulterated?
The price difference between different fuels is the main reason behind the adulteration. Gasoline carries a much higher tax than diesel, which in turn is taxed more than kerosene. Industrial solvents and recycled lubricants are other materials with little or no tax, which makes it lucrative to add as an adulterant.
