Citroen Fuel Drain


Putting Petrol in a Diesel Citroen is a fairly typical problem. And its remedy will depend on several different factors. If perhaps you want to find out what you should do about it then stay with me.
Here are the most crucial variables to think about whenever determining whether to get a fuel drain:

  1. What amount of Petrol have you put in to the Citroen, bearing in mind that the fuel capacity of the Citroen C8 HDi is usually around 80 litres?
    1. A tiny amount of Petrol, something like 4 litres of Petrol in a Diesel C8 HDi will in most cases not necessarily be a big problem. Experience has taught us that an amount under 4 litres (which is 5% of the overall fuel tank capacity) is oftentimes capable of being sufficiently diluted by means of wholly topping up the rest of the tank with the correct fuel.
      It's highly rare to encounter an automobile suffering from problems with lower than 5% wrong fuel contamination. Please remember it's infrequently found - in no way impossible to encounter. You will discover a number of vehicles that will not endure any amount of fuel contamination at all.
    2. Somewhere between 4 and 8 litres of Petrol in the Citroen (5 to 10%) is more of a 50/50 condition. Our practical experience demonstrates that as many people get away with this as all those who break down. Whenever you are figuring out whether to risk it and just top it up consider that it is exactly like wagering all of it on black - you will have a 50/50 chance of it working.
    3. Anything in excess of 8 litres of Petrol in your Diesel C8 HDi ought to straight away be removed because your likelihood of getting away with that quantity of contamination is very likely below one in fifty - definitely long odds.
  2. Put Petrol in a Diesel Citroen and drove it: Have you spotted any kind of performance difficulties ever since putting the bad fuel in the C8 HDi? If so, get it emptied no matter the volume of Petrol or the contamination ratio. Continuing to drive driving a car that is beginning to suffer the effect of fuel contamination can only cause progressively more harm being caused to your fuel system parts.
  3. Do you want peace of mind?
    You should get it removed. Regardless of contamination ratio, there is inevitably some degree of risk caused by driving a Diesel vehicle on Diesel contaminated with the wrong fuel. Probable outcomes of driving on the wrong fuel normally include the engine refusing to start, running lumpy, losing power, wearing of the high-pressure pump, worn out or blocked injectors, and the like. These are several of the most frequently seen Petrol in Diesel signs or symptoms, and should you detect any of them stop and get it removed right away.

Petrol in Diesel Questions

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.
