Oil prices have fallen for four straight weeks and have given up about 60 per cent since the start of the year. Petrol and diesel prices were left untouched for the 14th day in a row today despite crude oil rates slumping to a new 17-year-low. Although state-run fuel retailers review prices everyday at 6 am, rates have been kept unchanged for almost a fortnight now. So far in the month, fuel rates have become cheaper by more than ₹2 a litre.
