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 neighboring states. Even the aging 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.
