It’s easy to think that you’d never make the mistake of putting petrol into a diesel car. After all, how hard is it to remember what kind of fuel your car takes?

If it happens to you, it’s important to know what you need to do as having the right information means you can avoid damage to your engine.

Some of you are probably reading this and wondering how people could put the wrong fuel in their diesel car. Well, it can happen for a number of reasons. Firstly, there are more and more diesel cars on the road and they are now often as quiet as their petrol counterparts. This means that people can often assume they take petrol,particularly if the car is being borrowed or rented.

Even if the car belongs to you, old habits die hard and you might automatically fill up with petrol if you’re used to driving petrol cars. As you can see, it’s an easy enough mistake to make which is why you need to know what to you if it happens to you. It’s especially important to get the issue sorted out as quickly as possible as related damage may not be covered on your vehicle’s warranty.

What damage can it cause?

Obviously, diesel cars are not designed to take petrol and it can cause damage to the engine. Petrol can affect the lubrication in the pump affecting the metal components. Petrol can also damage the diesel pump and fuel system seals. The amount of damage caused depends on how long the engine was run after it was filled with petrol.
