Picture this: you’re in a rush to get to work and quickly pull into a petrol station to refuel your car. In your haste, you accidentally pump the wrong fuel into your vehicle. As you start the engine and drive away, you suddenly realise your mistake. What should you do now? This blog section will provide a comprehensive guide on what to do when you’ve put the wrong fuel in your car, the potential consequences, and how to avoid this situation.

Stay Calm and Assess the Situation

Before you panic, take a moment to assess the situation. Did you put petrol in a diesel car, or diesel in a petrol car? The severity of the problem and the steps you need to take differ depending on the type of fuel you’ve accidentally used. In either case, it’s essential to remain calm and follow the necessary steps to minimise any damage to your vehicle.

Petrol in a Diesel Car

Putting petrol in a diesel car is the more severe of the two scenarios. Petrol acts as a solvent in diesel engines, which can cause damage to the fuel pump and injectors. The first thing you should do if you realise you’ve put petrol in a diesel car is to stop driving immediately. The more you drive, the more damage you risk causing to your vehicle. Turn off the engine and safely park your car, then call a breakdown service or a wrong fuel removal specialist to help you.

Diesel in a Petrol Car

While putting diesel in a petrol car is still a cause for concern, it’s generally less severe than putting petrol in a diesel car. This is because diesel is heavier and oilier than petrol and will not ignite easily in a petrol engine. If you’ve put diesel in a petrol car, you should also turn off the engine and park your vehicle safely. Call a breakdown service or a wrong fuel removal specialist for assistance.

Call a Professional

Many breakdown services offer wrong fuel recovery, or you can contact a dedicated wrong fuel removal specialist. They will drain the contaminated fuel from your vehicle and flush the fuel system to remove any traces of the wrong fuel before refilling your car with the correct fuel. In most cases, this process can safely remove the wrong fuel without causing any significant damage to your vehicle.

Preventative Measures

To avoid accidentally putting the wrong fuel in your car in the future, consider taking the following precautions:

  1. Always double-check the fuel pump before refuelling your car. Take a moment to ensure you’re selecting the correct fuel type for your vehicle. 
  2. Attach a label or sticker to your fuel cap indicating the correct fuel type for your car. This can serve as a helpful reminder and prevent future mistakes. 
  3. If you’re driving a new or unfamiliar car, ensure you know the correct fuel type before refuelling. Check the owner’s manual or ask the owner if you’re unsure. 
  4. Pay attention when refuelling your car, even if you’re in a hurry. Taking a few extra seconds to ensure you’re using the correct fuel can save you from an expensive and time-consuming problem.


Accidentally putting the wrong fuel in your car can be a stressful situation. Still, it’s essential to stay calm and take the appropriate steps to minimise damage to your vehicle. Remember to turn off your engine, park your car safely, and call a professional. By following these steps and taking preventative measures to avoid future mistakes, you can ensure the safety and longevity of your vehicle.
