At present, Essar Oil sells petrol and diesel at par with PSU rates only in three states, including Gujarat and Karnataka. In the remaining states, it sells auto fuel at rates higher than those of state-run Indian Oil, Bharat Petroleum and Hindustan Petroleum.

"The international oil prices have fallen and as our pump rates are aligned to international prices, we will be reducing petrol and diesel prices from July 16," a company source said.

Last month, the company had raised diesel price by Rs 1-2 a litre and petrol rates by Rs 1-2.50 per litre as crude oil had climbed to USD 70 a barrel. With crude oil prices easing to under USD 61 per barrel, petrol and diesel prices are being cut by Rs 0.50 to Rs 2.50 a litre depending on location of the fuel stations, it said.

State-run oil firms last week raised petrol and diesel rates by Rs 4 a litre and Rs 2 a litre respectively to partly align them with rising crude oil prices. They sell petrol at Rs 48.76 a litre and diesel at Rs 36.70 a litre in Mumbai.
