Petrol and diesel prices will be revised on a daily basis from today in select cities of the country. <br/><br/>Public sector oil marketing companies will launch a pilot for daily revision of prices in Puducherry, Vizag in Andhra Pradesh, Udaipur in Rajasthan, Jamshedpur in Jharkhand and Chandigarh. <br/><br/>Instead of using fortnightly average, pump rates will reflect daily movement in international oil prices and rupee – US dollar fluctuations. The scheme will be extended to other parts of the country gradually. <br/><br/>Currently, the price of fuel is revised on 1st and 16th of every month based on the average international price of the products in the last fortnight and rupee-dollar exchange rates.
