Misfuelling (Wrong Fuel)
Misfuelling is filling a car with the wrong type of fuel, most often petrol in a diesel car.
What is Misfuelling (Wrong Fuel)?
Petrol in a diesel can damage the high-pressure pump and injectors. Diesel in a petrol car causes misfires and smoke. The less the engine runs, the lower the risk of damage. Misfuelling is often not covered by warranty, but some insurance policies cover it. Fuel nozzle size differences help prevent diesel in petrol cars.
How it works
The wrong fuel does not lubricate or burn as the system is designed for, causing wear or poor running.
Why it matters for your car
Do not start the engine or switch on the ignition if you notice before driving. Call breakdown assistance to drain and flush the system.
