Petrol and diesel prices in metro cities remained unchanged today after falling for five days in a row since daily retail fuel price revision was implemented nationwide on June 16. State-run Indian Oil Corp will continue to sell petrol for Rs 64.55 per litre in Delhi, and Diesel for Rs 63.96 per litre for the day (June 21-22) till 6 am on Thursday. Meanwhile, the price of the Indian basket of crude oil fell marginally to $45.84 per barrel on June 19 from $45.94 per barrel on June 16 - the previous trading day. Before today, the prices of petrol and diesel in metro cities were cut for five straight days after the implementation of daily price revision mechanism on June 16. In the five preceding days, the price of petrol fell by Rs 2.36 per litre in Delhi. The biggest cut of the lot was on June 16 itself, when the price was reduced by Rs 1.43 per litre (including state taxes and levies) after a gap of 15 days, as was the existing practice. Similarly, the price of diesel fell by Rs 1.98 per litre in five days, beginning with a cut of Rs 1.45 per litre (including state taxes and levies) on June 16 itself. New pricing mechanism The three state-run oil marketing companies Indian Oil Corp, Bharat Petroleum Corp and Hindustan Petroleum Corp have begun daily revision of retail prices of petrol and diesel all across the country with effect from June 16. The roll out of daily price revision mechanism nationwide comes close on the heels of a pilot project to review petrol and diesel prices on a daily basis in five cities from May 1. This is a departure from the existing practice of review in the prices of petrol and diesel every fortnight, and is a leap further towards true deregulation. With daily revision however, chances of major changes in the prices are very low, and the rise or cut would mostly be in few paise, of course depending on the movement in the crude oil prices. Albeit, to add to the confusion for consumers, the prices may vary from town-to-town or even from dealer-to-dealer, though again, by just a few paise. How to check daily price Oil marketing companies have introduced several methods for consumers to check the day\u2019s fuel price at a particular retail outlet, which will be effective from 6 am that day. Consumers can check the prices through SMS alerts, oil companies\u2019 mobile apps, websites and toll-free phone numbers. Customers could type RSP<SPACE>DEALER CODE, and send to 9224992249 for Indian Oil; 9223112222 for Bharat Petroleum; and 9222201122 for Hindustan Petroleum. Outlet-wise price information will also be available on the companies\u2019 websites, and mobile apps, namely Fuel@IOC, SmartDrive (BPCL), and My HPCL.
