New Delhi, Nov 18 (TIWN) The news of a successful vaccine against coronavirus has brought fresh energy in the oil markets with global crude oil prices crossing $ 44 a barrel mark.

While an increase in crude prices has been welcomed across major global oil producers, at home oil marketing companies are looking at this firming up with concern. The concern now is that at this level of crude and higher product prices, it would be difficult to keep the retail price of petrol and diesel steady for any time longer.  The OMCs did not effect any revision in retail price of petrol and diesel across the country on Tuesday maintaining the trend set a couple of months back when last fuel price revision was done.
