Citroen Fuel Drain


Filling Diesel in a Petrol Citroen is a fairly typical mistake to make. And its solution depends on several different factors. If perhaps you would like to know what you need to do to sort it out then please read on.
Listed below are the key factors to to consider when determining whether or not to get a fuel drain:

  1. What amount of Diesel have you put in the Citroen, bearing in mind that the fuel capacity of the Citroen xM is probably about 80 litres?
    1. A tiny quantity of Diesel, as little as 4 litres of Diesel in a Petrol xM will usually not be a big problem. Experience has taught us that anything less than 4 litres (about 5% of the fuel tank capacity) is often capable of being sufficiently diluted simply by wholly topping up the tank with Petrol.
      It is very rare to come across a car going through problems because of lower than 5% incorrect fuel contamination. Be aware that it is rare - in no way impossible to find. There are actually a few vehicles that won't stand any degree of fuel contamination whatsoever.
    2. In between 4 and 8 litres of Diesel in the Citroen (5 to 10%) is really a 50/50 scenario. Our experience demonstrates that as many people get away with this as all those who break down. Whenever you are deciding whether to chance it and just simply top it up remember that it is much like gambling all of it on black - you have a 50/50 chance of it working.
    3. Anything above 8 litres of Diesel in your Petrol xM really should straight away be removed as your likelihood of driving with that level of contamination is more than likely less than one in fifty - seriously long odds.
  2. Put Diesel in a Petrol Citroen and drove it: Have you observed any kind of performance troubles after putting the wrong fuel in the xM? If you have, get it drained regardless of the amount of Diesel or the contamination ratio. Continually running a motor vehicle that is now starting to suffer from the effect of wrong fuel contamination will probably definitely end up in more harm being done to the fuel system components.
  3. Do you want security?
    Simply get it emptied. No matter the contamination percentage, there is invariably some amount of danger connected to driving a Petrol engine on fuel contaminated with Diesel. Likely outcomes of driving on the incorrect fuel normally include the engine refusing to start, running unevenly, losing power, degradation of the high-pressure pump, worn out or clogged injectors, etc. These are a few of the commonest Diesel in Petrol signs and symptoms, and should you notice any of them cease driving and have it drained as soon as possible.

Diesel in Petrol Questions

When someone has put Diesel in a Petrol car they have a few very common questions. So we have compiled a list of the most Frequently Asked Questions for you

I put Diesel in a Petrol car and drove it. What do I do?


Turn off the car as soon as possible and call us. Continuing to run a vehicle on the wrong fuel can potentially damage it. We will be able to give you advice and assistance based on your circumstances

Will driving a Petrol car on Diesel cause damage to it?


It can. However, if the problem is caught and remedied quickly the risks will be minimal. Of the 1,500 vehicles we attend every month, less than 0.5% have suffered and substantial damage requiring parts replacement.

How much Diesel can I get away with in a Petrol car?


The safe answer is none. However you might be able to get away with a very low contamination ratio. That being said, we always highly recommend draining anything over a 5% contamination ratio asap.

I know about petrol in diesel, but what about Super Unleaded?


Putting Super Unleaded, or Shell V-Power, BP Ultimate Unleaded, etc, will have the exact same effect as putting regular unleaded petrol in your diesel car and will need to be drained out and flushed.

Will getting you to do a fuel drain void my warranty?


No! The EU Block Exemption Regulations clearly state that "the work can be carried out by as long as that garage uses manufacturer approved parts and correctly follows the manufacturer's service schedule."

Can I top it up with Petrol and add some 2-stroke oil?


This might work on some vehicles in some cases, but in the majority on instances it won't and you risk damaging the Lambda sensors as well as fuel pump and injectors, just as a regular misfuel.
