What to Do If You Put the Wrong Fuel in Your Car: A Comprehensive Guide

We've all had those moments of distraction when filling up our cars at the fuel station. You might have accidentally grabbed the wrong pump, and now you're facing the dreaded realisation that you've put the wrong type of fuel in your vehicle.

Don't panic; it's a common mistake, and there are steps you can take to minimise the damage to your engine and get back on the road. In this guide, we'll walk you through what to do if you find yourself in this situation.

Step 1: Don't Start the Engine

As soon as you realise you've used the wrong fuel, do not start your car. Starting the engine will circulate the incorrect fuel through the system, potentially causing damage to the engine, fuel lines, and other components.

Step 2: Push or Tow Your Car

If you're at the fuel station, ask for assistance in pushing your car to a safe location. If you've driven a short distance, it might be necessary to have your vehicle towed to a repair facility. Remember that attempting to drive even a short distance with the wrong fuel can exacerbate the problem.

Step 3: Call for Professional Assistance

Contact a professional mechanic or your breakdown service. They are experienced in dealing with misfuelling incidents and will be able to assess the situation. They will also advise on the best course of action to rectify the problem.

Step 4: Drain and Clean the Fuel System

The most common solution for dealing with the wrong fuel in your car is to drain and clean the fuel system. This process involves removing the contaminated fuel, flushing the fuel lines and tank, and refilling with the correct fuel. Do not attempt to do this yourself unless you are a trained mechanic.

Step 5: Replace the Fuel Filter

In some cases, the wrong fuel may have clogged the fuel filter. Your mechanic will likely recommend replacing the fuel filter to ensure the system is completely clean and free from any residual contaminants.

Step 6: Inspect for Any Damage

After the fuel system is cleaned and the correct fuel is added, your mechanic should perform a thorough inspection to ensure that no lasting damage has occurred. Modern vehicles are equipped with various safety mechanisms to prevent severe damage in the event of misfuelling, but it's crucial to check for any potential issues.

Step 7: Prevent Future Misfuelling

To avoid making the same mistake in the future, consider using fuel caps or adapters designed to prevent the wrong nozzle from fitting into your fuel filler neck. You can also make a habit of double-checking the label on the pump before refuelling.

Putting the wrong fuel in your car can be a stressful experience, but it's a mistake that can be rectified. The key is to stay calm, avoid starting the engine, and seek professional assistance to drain, clean, and inspect your fuel system. By taking these steps, you can minimise potential damage and get back on the road safely. Remember, it happens to the best of us, and what's most important is handling the situation wisely and responsibly.
