Citroen Fuel Drain


Filling up with Diesel in a Petrol Citroen is a common mistake. And its solution varies according to a number of factors. Assuming you want to find out what you need to do about it then keep on reading.
Listed below are the key factors to take into consideration when choosing whether to have a fuel drain:

  1. Exactly how much Diesel have you put in to the Citroen, keeping in mind that the fuel capacity of your Citroen C4 Grand Picasso is in most cases about 60 litres?
    1. A small quantity of Diesel, as little as 3 litres of Diesel in a Petrol C4 Grand Picasso will more often than not not necessarily be a major problem. Experience has shown us that quantities under 3 litres (almost 5% of the fuel tank volume) is usually able to be sufficiently diluted by entirely topping up the rest of the tank with Petrol.
      It is highly unusual to encounter a car or truck having problems with below 5% wrong fuel contamination. Be aware that it's infrequently found - certainly not impossible to find. There are actually a number of cars that will not endure any quantity of contamination in the slightest.
    2. In between 3 and 6 litres of Diesel in the Citroen (5 to 10%) is really a 50/50 condition. Our experience has shown that as many motorists get away with it as those who don't. Whenever you are deciding upon whether to chance it and basically fill it up bear in mind that it is very much like wagering everything on black - you've got a 50/50 possibility of it working out.
    3. Anything more than 6 litres of Diesel in your Petrol C4 Grand Picasso must as soon as possible be removed since your likelihood of driving with that amount of contamination is certainly less than one in 50 - genuinely huge odds.
  2. Put Diesel in a Petrol Citroen and drove it: Have you spotted any performance concerns since putting the incorrect fuel in the C4 Grand Picasso? In that case, get it emptied regardless of the volume of Diesel or even the contamination ratio. Continually driving a motor vehicle that is starting to suffer from the consequences of fuel contamination can likely bring about more and more harm affecting the fuel system parts.
  3. Do you want reassurance?
    Then get it emptied. No matter the contamination percentage, there is inevitably some extent of threat connected with operating a Petrol motor on Petrol contaminated with Diesel. Likely outcomes of driving on the incorrect fuel normally include the motor not starting, running lumpy, lack of power, wearing of the high-pressure pump, worn or blocked injectors, and so on. These are some of the most frequently seen Diesel in Petrol signs and symptoms, and in the event that you notice any of them cease driving and get it removed 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.
