MUMBAI: Petrol in Mumbai reached the highest-ever rate on Sunday morning at Rs 86.25 per litre . Diesel too touched a new high of Rs 75.12 per litre. The prices are expected to escalate further, said sources in oil marketing companies.While it will pinch the motorists who are already fuming with low mileage and more fuel consumption due to road congestion, transporters are burdened with the diesel price hikes which continue for a fortnight now.As for LPG gas rates in Mumbai, a non-subsidised consumer will now have to shell out Rs 795, the highest ever for an LPG cylinder. The city has a significant number of non-subsidised customers and they will end up paying more for a 14.2kg domestic gas cylinder.
