Citroen Fuel Drain


Filling up with Diesel in a Petrol Citroen is a common mistake. And exactly what you need to do about it varies according to various factors. If you would like to find out what you have to do to sort it out then continue reading.
Here are the key variables to take into consideration when making a decision whether or not to get the car drained:

  1. What amount of Diesel did you put in the Citroen, taking into account that the fuel tank capacity of your Citroen DS5 is in most cases about 60 litres?
    1. A modest quantity of Diesel, as little as 3 litres of Diesel in a Petrol DS5 will typically not necessarily be a major problem. Experience has demonstrated to us that quantities under 3 litres (about 5% of the fuel tank volume) is quite often able to be adequately diluted simply by wholly filling up the remainder of the tank with Petrol.
      It's relatively unusual to come across a motor vehicle experiencing difficulties with below 5% wrong fuel contamination. Remember that it is uncommon - not impossible to encounter. You will discover a number of vehicles that won't stand any amount of contamination at all.
    2. Anywhere between 3 and 6 litres of Diesel in the Citroen (from 5 to 10%) is a 50/50 situation. Our experience has confirmed that as many motorists get away with it as all those who break down. Any time you're trying to decide whether to chance it and simply fill it up consider that it is the same thing as gambling all of it on black - you have got a 50/50 chance of it working.
    3. Anything over 6 litres of Diesel in a Petrol DS5 must right away be drained out seeing that your probability of getting away with this level of contamination is more than likely less than one in fifty - seriously huge odds.
  2. Put some Diesel in a Petrol Citroen and drove it: Have you observed any kind of performance issues ever since putting the bad fuel in your DS5? If so, get it emptied irrespective of the quantity of Diesel or the contamination percentage. Continually running a motor vehicle that is now beginning to suffer the consequences of fuel contamination will probably likely be responsible for more and more damage affecting the fuel system.
  3. Are you looking for security?
    Simply get it drained. No matter the contamination percentage, there is always a certain level of threat linked with operating a Petrol motor on fuel contaminated with Diesel. Possible implications of driving a car on the wrong fuel can include the engine not starting, running lumpy, lack of power, wearing of the high-pressure pump, worn or clogged injectors, and so forth. These are several of the most common Diesel in Petrol symptoms, and in the event that you recognise any of them stop driving and get 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.
