Citroen Fuel Drain


Putting Petrol in a Diesel Citroen is a well-known problem. And its remedy is based on a variety of things. Assuming you want to find out what to do about it then please read on.
These are the most crucial factors to keep in mind whenever making a decision whether to have the car drained:

  1. How much Petrol did you put into the Citroen, considering that the fuel capacity of your Citroen C4 Grand Picasso HDi is normally roughly 55 litres?
    1. A modest amount of Petrol, as little as 2.75 litres of Petrol in a Diesel C4 Grand Picasso HDi will typically not necessarily be a huge problem. Experience has demonstrated to us that an amount under 2.75 litres (roughly 5% of the fuel tank volume) is very often able to be adequately diluted through totally topping up the remainder of the tank with the right fuel.
      It is quite unusual to find a vehicle experiencing problems because of under 5% wrong fuel contamination. Be aware that it is uncommon - definitely not impossible to encounter. You will discover a number of vehicles that don't stand any degree of fuel contamination whatsoever.
    2. Somewhere between 2.75 and 5.5 litres of Petrol in the Citroen (5 to 10%) is really a 50/50 scenario. Our practical experience has confirmed that as many motorists get away with it as those who break down. Any time you're deciding on whether or not to risk it and simply top it up bear in mind that it is just like gambling all of it on black - you've got a 50/50 chance of it being ok.
    3. Anything in excess of 5.5 litres of Petrol in a Diesel C4 Grand Picasso HDi should promptly be drained out since your likelihood of driving with that amount of contamination is almost certainly less than one in 50 - genuinely long odds.
  2. Put some Petrol in a Diesel Citroen and drove it: Have you noticed any performance concerns since putting the wrong fuel in the C4 Grand Picasso HDi? If that's the case, have it emptied no matter the quantity of Petrol or even the contamination ratio. Still driving a car that is currently beginning to suffer from the consequences of fuel contamination can likely lead to more harm affecting your fuel system parts.
  3. Do you want security?
    You should get it emptied. No matter the contamination ratio, there is invariably some degree of risk in connection with operating a Diesel engine on Diesel contaminated with Petrol. Probable results of driving on the wrong fuel include the motor not starting, running lumpy, decrease in power, degradation of the high-pressure pump, worn or bunged injectors, and so forth. These are a few of the most frequently seen Petrol in Diesel symptoms, and if you recognise any of them cease driving and get it removed immediately.

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.
