Fake products in India are not only widely spread in the market but it has reached your fuel tank too. In the last three-and-a-half years, a total of 4,375 cases of fuel adulteration have been registered in the country, out of which 33 retail outlets have already been permanently shut down, Dharmendra Pradhan, Minister of Petroleum & Natural Gas, reveals in a reply to a question in Rajya Sabha. While adulteration in fuel damages the vehicle, it becomes more dangerous because it generates significant health hazards too. Adulterated petrol and diesel emit dangerous levels of hydrocarbons, carbon monoxide, oxides of nitrogen, particulate matter and can cause increased emissions of air toxic substances.
