Stocks of oil marketing companies such as Indian Oil, HPCL and BPCL may remain active, after they increased the prices of petrol and diesel.

According to OMCs, the price of petrol has been increased by ₹3.07 a litre and that of diesel by ₹1.90. The action was necessitated following a sharp surge in crude oil prices from $28.83 a barrel (in February) to the current level of about $37.5.

The revision will take effect from midnight.
