Wrong Fuel! What Next?

According to the AA, at least 150,000 drivers put the wrong fuel in their car every year. However, many people don’t know what to do if they find themselves in the same situation.

Here at Wrong Fuel, we can help you if you misfuel your car, and here are some helpful tips on what you should do if you fill your car with the wrong fuel.


Misfuelling your car isn’t as much of a disaster as you might think, providing you take the right steps once you realise.

Even though putting the wrong fuel in your car can’t be undone, it doesn’t have to be a complete catastrophe. By staying calm and using your common sense, you can save yourself time and lower the risk of causing more damage to your car.

Don’t Turn on Your Ignition

If you realise immediately after you have put the fuel in your car that you‘ve filled it with the wrong fuel, it is vital that you do not turn on the ignition.

This could potentially save you a lot of time and money, as you can prevent the incorrect fuel being drawn up into the engine and causing damage.

If you have a car that runs on diesel, the fuel pump will typically be lubricated by the diesel in order to allow it to run smoothly. However, if you have put petrol into your car instead, it can act as a solvent, removing this lubrication and causing metal parts inside the car to grind together and become damaged.

If your car normally runs on petrol and you fill it with diesel, the good news is that the damage caused to your engine won’t be as severe. However, it will still cause smoke to come out of the engine and prevent it from running correctly.

Of course, you may not realise when the car is stopped that you have misfuelled it, in which case you will most likely realise when you’re driving and your car suddenly starts to lose power. If this happens, you must pull over, turn on your hazard lights and call a breakdown assistance service immediately. If you have broken down and you are blocking the road, you must notify police.


Doing the Maths

Realising you have put the wrong fuel in your car can be a blessing, and there is no better time to realise this than while you are filling up at the garage.

Although it is normally best to drain your tank after you misfuel, you can sometimes fix the situation without needing assistance.

Once you realise your mistake, try to figure out how much of the wrong fuel you have put into your car. If you have put in below 10% of your fuel tank, you can often fill the remainder of the tank with the correct fuel and you will have no issues.

However, if you have filled up more than 10% of your tank capacity or you are unsure how much of the wrong fuel you’ve put into your car, it is important that you do not turn on the engine. Call for assistance instead.

Call for Assistance

Whether you have broken down on the motorway or are stuck at the petrol station, you will need to call a breakdown service, as a misfuelled car requires professional attention.

Some cars may be able to be fixed there and then, although it is highly likely that your car will need to be transported to a local mechanic in order for the tank to be drained and any repairs carried out.

Of course, the first step you must take when misfuelling your car is to stay calm! Even if you have started your car, you can be back on the road in no time with the right help.
