A hike of about Rs 2.10-2.13 per litre in petrol price is needed because of weakening Indian currency.

It may be noted that State-owned Oil companies, as per practise, revise rates of petrol on 1st and 16th of every month based on the average imported price and exchange rate during the fortnight.

As per sources, Oil companies are likely to revise rates on Monday.

The rate change may, however, need a political clearance as Assembly elections in five states have been announced.
