Citroen Fuel Drain


Filling Diesel in a Petrol Citroen is a regular mistake. And its solution is dependent upon several different factors. If perhaps you want to find out what it is advisable to do to fix it then continue reading.
Let us discuss the most important variables to be aware of when deciding whether to have the car drained:

  1. Exactly how much Diesel did you put in the Citroen, bearing in mind that the fuel capacity of your Citroen C8 is in most cases around 80 litres?
    1. A modest amount of Diesel, something like 4 litres of Diesel in a Petrol C8 will in most situations not necessarily be a significant problem. Experience has proven to us that anything under 4 litres (roughly 5% of the total fuel tank capacity) is very often capable of being adequately diluted through wholly filling up the tank with Petrol.
      It's relatively uncommon to encounter a vehicle going through issues due to below 5% wrong fuel contamination. Be aware that it's unusual - not impossible to encounter. There are actually certain automobiles that will not stand any quantity of contamination in the slightest.
    2. In between 4 and 8 litres of Diesel in the Citroen (5 to 10%) is more of a 50/50 situation. Our practical experience demonstrates that as many people get away with it as those who don't. Whenever deciding upon whether to chance it and just simply top it up recognise that it is very much like wagering it all on black - you've got a 50/50 chance of it working.
    3. Anything over 8 litres of Diesel in a Petrol C8 must right away be drained seeing that your probability of driving with this level of contamination is certainly less than one in 50 - really long odds.
  2. Put Diesel in a Petrol Citroen and drove it: Have you detected any performance troubles since putting the incorrect fuel in your C8? If so, get it removed irrespective of the volume of Diesel or the contamination ratio. Continually driving a motor vehicle that is now beginning to suffer from the effects of fuel contamination can definitely be responsible for increasing amounts of damage being done to your fuel system.
  3. Do you need peace of mind?
    Simply get it drained. No matter the contamination percentage, there is always some amount of threat associated with operating a Petrol vehicle on Petrol contaminated with Diesel. Probable final outcomes of driving a vehicle on the incorrect fuel normally include the motor refusing to start, running lumpy, loss in power, wearing of the high-pressure pump, damaged or bunged injectors, and so forth. These are several of the most frequently seen Diesel in Petrol signs and symptoms, and should you recognise any of them stop and have it drained right now.

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.
