• MANGALURU: Have you ever asked a petrol pump employee to fill up your fuel tank – say a 42-litre tank – and was handed over a bill for 50 litres of fuel? Well, if you have experienced this and held the petrol pump attendant responsible, you may be wrong. The issue may lie with your fuel tank and not the petrol pump.
• A police complaint against a petrol pump led to the discovery that the fuel tank capacity mentioned by the car manufacturer is just the 'safe filling' and not the actual capacity of the tank.
