Private fuel retailer Nayara Energy on Thursday raised petrol prices by Rs 5 per liter and diesel by Rs 3 per litre, in line with the rise in global oil prices due to the war in West Asia.Nayara, owned by Russia’s Rosneft, operates about 7,000 of its more than 1 lakh filling stations across the country, mainly on national highways and urban centres. However, another private retailer Jio-bp has not increased the prices so far. Officials said private fuel retailers, unlike state-owned companies, do not receive any government compensation to offset losses incurred by preventing price increases.
