Help, I’ve filled up with the wrong fuel petrol in my diesel car or diesel in my petrol car. What do I do now?

If you haven’t already, don’t start the car. Call 0345 017 0729 straight away and tell our customer service agent the nature of your problem, whether you’ve put diesel in a petrol car or vice versa. We will aim to get to you within 1 hour of your call. Next, explain to the fuel station forecourt representative what has happened. If you have driven the car and have broken down in the road at the side of the road, put up your emergency warning triangle (if you have one) and make sure that you are safely away from the road whilst you are waiting for our engineer.

I put the wrong fuel in my car, is it going to be expensive to fix?
Not necessarily, if you filled up with the wrong fuel but didn’t start the engine then the fuel drain is straight forward and prices start from £99. There is potentially a problem if you have driven the car with the wrong fuel in it but please do check with one of our technicians, especially before taking the vehicle to a main dealer who may quote for expensive engine component replacement that may not really be required.

Does my emergency breakdown cover include mis-fuelling?

Not unless you have specifically requested it. If you call your breakdown service guys, they will most likely tow your vehicle to a local garage or to your home, whichever is nearest. You can call us from your vehicle location and we will come out to resolve your “wrong fuel in vehicle” situation.

How can I make sure that I don’t put the wrong fuel in my car?

To prevent misfuelling; you cannot always simply rely on the fuel station to get everything right. Hose colours, pump placements or even nozzle colours change, now that every fuel pump has an advert on it and every fuel station has branded fuel you do need to be very careful as it can be confusing even for motorists with many years of experience.

1) Read the fuel type on your car/vans filler area (usually on the inside of the covering flap.
2) Check the nozzles and find the one that reads ”Diesel” (or petrol if your driving petrol
3) Check that the end of the DIESEL PISTOL HOSE IS LARGER THAN THE END OF THE PETROL PISTOL. Compare the two side by side if necessary to be absolutely sure. This is the only failsafe method of ensuring that you don’t put the wrong fuel type in your car. Putting diesel into a petrol vehicle is much less likely because you won’t normally be able to fit the diesel hose end into an unleaded petrol tank entry, it will be too big to fit.

What licences are required by my fuel evacuation engineer?

A reputable fuel evacuation engineer must have an SPA passport and an ADR licence. These allow the engineer to work on a fuel station forecourt and to transport potentially dangerous goods (i.e. contaminated fuel). These functions can only be carried out by a skilled engineer who has received the correct training.
