1. Read the article. Which driver made the bigger mistake?

The cost of misfuelling Every year, thousands of drivers put the wrong fuel in their car. In the UK, the number is over 150,000 drivers in a year! Peter Coburg put petrol into his friend’s diesel car. It cost me over £1,000 to put things right!’

If you’ve put the wrong fuel in your car, don’t start the engine. If the wrong fuel circulates around the fuel system, it will cause damage. Some cars have an electric pump. This starts to work immediately when you switch on the ignition. So, don’t switch on the ignition.

What damage could you cause? Diesel acts as a lubricant for moving parts. Petrol in diesel acts as a solvent, i.e. it reduces lubrication. Then metal parts rub against metal parts and cause damage. The further the petrol goes, the more parts are damaged: the pumps, the injectors, the fuel rail and the fi lters. You might have to fi t a new engine.

So what should you do if you’ve put the wrong fuel in your car? You can call a specialist service. The mechanic will fi rst drain the wrong fuel and take it away. Next, he/she will (= wash out) the parts that have been in contact with the wrong fuel. Finally, he/she will refi ll the tank with the correct fuel.

One driver told us about his worst mistake: I was delivering diesel in a tanker to a garage. I was in a hurry, and I put the wrong fuel in the tank. I pumped 36,000 litres of petrol into a diesel tank. I lost my job the next day.’
