Petrol in India is traded at Rs undefined per litre in New Delhi, Rs undefined per litre in Kolkata, Rs 100.79 per litre in Chennai. Earlier the petrol and diesel prices were revised every fortnight, which means the petrol price and diesel price changed on the 1st and the 16th of every month. However, from June 2017, a new scheme was implemented under which petrol prices are being revised every morning at 6 am. The petrol price and diesel rate are being revised on a regular basis due to dynamic fuel pricing.
