Citroen Fuel Drain


Filling up with Diesel in a Petrol Citroen is a regularly occurring mistake. And exactly what you should do about it hinges on a variety of things. Assuming you want to know what to do to fix it then read on.
Here are the key variables to to consider whenever deciding on whether or not to have it drained:

  1. What amount of Diesel did you put in to the Citroen, considering that the fuel tank capacity of your Citroen Saxo is in most cases around 45 litres?
    1. A modest quantity of Diesel, less than 2.25 litres of Diesel in a Petrol Saxo will normally not be a big problem. Experience has proven to us that quantities under 2.25 litres (which is about 5% of the whole fuel tank volume) is usually capable of being completely diluted by entirely topping the remainder of the tank with Petrol.
      It is relatively unusual to encounter a motor vehicle having problems because of under 5% wrong fuel contamination. Do not forget that it is infrequently found - not impossible to encounter. There are actually certain vehicles that won't endure any degree of contamination whatsoever.
    2. Between 2.25 and 4.5 litres of Diesel in the Citroen (from 5 to 10%) is more of a 50/50 scenario. Our expertise has shown us that as many drivers get away with this as those people who don't. Whenever figuring out whether to risk it and just simply fill it up bear in mind that it is very much like gambling everything on black - you have a 50/50 chance of it working out.
    3. Anything more than 4.5 litres of Diesel in a Petrol Saxo should really straight away be drained because your likelihood of succeeding with this quantity of contamination is probably lower than one in 50 - genuinely big odds.
  2. Put some Diesel in a Petrol Citroen and drove it: Have you noticed any performance difficulties ever since putting the wrong fuel in the Saxo? In that case, have it removed no matter the quantity of Diesel or even the contamination ratio. Proceeding to drive driving a motor vehicle that is beginning to suffer from the effects of fuel contamination can definitely bring about more and more harm being done to the fuel system components.
  3. Do you need security?
    In that case get it removed. Regardless of the contamination ratio, there is always some amount of risk resulting from driving a Petrol motor on fuel contaminated with the incorrect fuel. Possible implications of driving on the wrong fuel include things like the motor not starting, running unevenly, loss of power, wearing of the high-pressure pump, worn out or bunged injectors, etc. These are several of the most common Diesel in Petrol symptoms, and in the event that you detect any of them then stop and have it removed right away.

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.
