Citroen Fuel Drain


Filling Petrol in a Diesel Citroen is a very common error. And what you want to do about it is dependent upon several different things. Assuming you want to find out what you need to do to fix it then keep reading.
Let us discuss the key variables to be aware of whenever making a decision whether or not to get your car drained:

  1. What amount of Petrol have you put in to the Citroen, taking into consideration that the fuel tank capacity of the Citroen C6 Hdi is normally around 72 litres?
    1. Hardly any Petrol, less than 3.6 litres of Petrol in a Diesel C6 Hdi will typically not be a significant problem. Experience has taught us that an amount under 3.6 litres (approximately 5% of the fuel tank) is often able to be completely diluted by wholly topping the remainder of the tank with Diesel.
      It is pretty uncommon to find a motor vehicle going through difficulties because of below 5% incorrect fuel contamination. Keep in mind it is uncommon - in no way impossible to encounter. There are actually a few cars that don't endure any level of contamination in the slightest.
    2. Anywhere between 3.6 and 7.2 litres of Petrol in the Citroen (from 5 to 10%) is really a 50/50 condition. Our expertise has shown us that as many motorists get away with this as those people who break down. Whenever you are deciding upon whether to chance it and basically top it up bear in mind that it is the same thing as betting your car on black - you have got a 50/50 chance of it working.
    3. Anything in excess of 7.2 litres of Petrol in a Diesel C6 Hdi really should promptly be removed seeing as your probability of getting away with that quantity of contamination is very likely below one in 50 - seriously huge odds.
  2. Put Petrol in a Diesel Citroen and drove it: Have you spotted any performance problems ever since putting the bad fuel in the C6 Hdi? In that case, have it drained no matter the volume of Petrol or the contamination ratio. Proceeding to run driving a car that is beginning to suffer the effect of wrong fuel contamination will probably just end up in more damage affecting the fuel system components.
  3. Do you need assurance?
    You should get it drained. Regardless of contamination percentage, there is invariably some extent of threat caused by running a Diesel engine on fuel contaminated with the incorrect fuel. Possible results of driving on the incorrect fuel include things like the motor refusing to start, running unevenly, reduced power, degradation of the high-pressure pump, worn or bunged injectors, and the like. These are some of the most frequently seen Petrol in Diesel warning signs, and should you detect any of them then stop and have it drained asap.

Petrol in Diesel FAQs

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

I put Petrol in a Diesel 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 Diesel car on Petrol 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 Petrol can I get away with in a Diesel 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 Diesel 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.
