Delhi, the National Capital of India has silently switched to BS VI grade fuel ahead of the 1st April 2018 schedule. Delhi state has about 397 retail fuel pump outlets and almost all of them now offer cleaner BS VI grade fuel. Delhi has become the first city in the country to offer BS VI grade fuel in India.
Even though the deadline for the automakers to start selling BS VI compliant vehicle only by September 2020, the BS VI fuel will be made available much before the deadline for the cars. The earlier roll out of the cleaner fuel was taken in November 2017 when Delhi was suffering from severe smoke caused by the crop stubble burning by the farmers in the neighbouring states. Even the ageing vehicles were targetted during this and the oil minister, Dharmendra Pradhan ordered the state-run fuel retailers to supply BS-VI fuels in Delhi from 1st April 2018.
The BS VI grade fuel available in India is similar to what the Euro VI grade fuel offers but they are exactly not the same. In BS VI grade diesel fuel, the sulphur level has come down from 50 ppm to 10 ppm. The petrol BS VI grade fuel also gets a lower grade of sulphur from 50 ppm to 10 ppm while the lead content is now down from 0.005 g/l to 0.001 g/l. The lower number of lead and sulphur leads to better emission exhaust and a cleaner environment.
Many oil companies even claimed that the exhaust emissions of the BS VI fuel will be much better than the vehicles running on CNG. However, if the fuel is used in the BS IV fuel tuned vehicle, it will not be of much help. Currently, only Mercedes-Benz offers the BS VI compliant S-Class in India. The BS VI fuel was earlier said to be hurting the BS-IV vehicles due to the lower level of lubrication. However, the transport ministry said that the BS VI fuel will come with additives that will make sure the new fuel offers the same level of lubrication as the BS IV fuel.
