New Delhi, Oct 17 : Petrol and diesel prices on Sunday rallied to their highest ever levels across the country, as fuel rates were hiked again by 35 paise a litre. The price of petrol in Delhi rose to its highest-ever level of Rs 105.84 a litre and Rs 111.77 per litre in Mumbai, according to a price notification of the state-owned fuel retailers. In Mumbai, diesel now comes for Rs 102.52 a litre; while in Delhi, it costs Rs 94.57. This is the fourth straight day of 35 paise per litre increase in petrol and diesel prices. There was no change in rates on October 12 and 13. Diesel prices have now increased 19 out of the last 23 days taking up its retail price by Rs 5.95 per litre in Delhi. With diesel prices rising sharply, the fuel is now available at over Rs 100 a litre in several parts of the country. This dubious distinction was earlier available to petrol that had crossed Rs 100 a litre-mark across the country a few months earlier. Petrol prices had maintained stability since September 5, but oil companies finally raised the pump prices last week. Petrol prices have also risen on 16 of the previous 19 days taking up its pump price by Rs 4.65 per litre. OMCs had preferred to maintain their watch prices on the global oil situation before making any revision in prices. This is the reason why petrol prices were not revised for the last three weeks. But extreme volatility in the global oil price movement has now pushed OMCs to effect the increase. Crude price has been on a surge rising over three year high level of over $ 84.6 a barrel now. Since September 5, when both petrol and diesel prices were revised, the price of petrol and diesel in the international market is higher by around $9-10 per barrel as compared to average prices during August. /IANS
