Petrol and Diesel will be cheaper by two rupees per litre from midnight tonight. The Central government today reduced the basic excise duty rate on Petrol and Diesel by two rupees per litre. The reduction will apply on both branded and unbranded Petrol and Diesel. The decision came in the wake on rising prices of the two petroleum products and criticism of the government by opposition parties. The move is expected to provide much needed relief to the common man.
