India's preparation for the world's cleanest petrol and diesel eventuality is nearing its end. With the switch from Euro 4 to Euro 6, from April 1, the minimum fuel available for pumping in India is the presence of pollutants, including sulfur.
The oil companies are preparing to supply petrol and diesel supplements parallel to the introduction of the Bharat Stage-6, the BS-6, the latest standard for controlling the number of pollutants emitted by a vehicle engine. The shifting is from the current BS-4 standard to the level of BS-6.
The decision to adopt the BS5 in 2019 and the BS6 in 2023 was later revised to take into account the critical situation in the country. The BS standard is similar to the Euro regulations in Europe. The BS4 fuel contains 50 ppm (parts per million) of sulfur. Only 10 ppm on BS-6. The amount of nitrogen oxide is also nominal.
State-run oil companies have invested an additional Rs 35,000 crore in refining the plant for refining a sulfur-deficient fuel, which is in addition to the Rs 600,000 crore that was spent after the BS-4 condition. Sanjiv Singh, chairman of IOC, which controls nearly half of the country's fuel market, said that almost all refineries have started delivering BS-6 fuel, which has reached storage depots across the country.
In the early 1990s, India adopted its first fuel refurbishment program. Low Lead Gasoline (Petrol) was introduced in 1994 in Delhi, Mumbai, Kolkata and Chennai. On February 1, 2000, a nationwide non-black fuel was made mandatory.
