Peugeot Fuel Drain


Filling Petrol in a Diesel Peugeot is a well-known mistake. And its remedy depends on several different things. Assuming you would like to find out what it is advisable to do about this then stay with me.
These are the main variables to consider whenever determining whether or not to get a fuel drain:

  1. How much Petrol have you put into the Peugeot, considering that the fuel tank capacity of the Peugeot 306 Hdi is in most cases roughly 60 litres?
    1. A modest amount of Petrol, as little as 3 litres of Petrol in a Diesel 306 Hdi will typically not really be a huge problem. Experience has shown us that quantities under 3 litres (about 5% of the entire fuel tank capacity) is frequently able to be completely diluted by totally filling up the rest of the tank with Diesel.
      It's relatively rare to find a vehicle going through issues with less than 5% incorrect fuel contamination. Be aware that it is very infrequent - certainly not impossible to encounter. There are actually a few vehicles that won't stand any quantity of fuel contamination whatsoever.
    2. In between 3 and 6 litres of Petrol in the Peugeot (from 5 to 10%) is really a 50/50 situation. Our practical experience has proven that as many motorists get away with it as all those who don't. When you are deciding whether to risk it and simply top it up consider that it is much like wagering all of it on black - you have a 50/50 chance of it working out.
    3. Anything over 6 litres of Petrol in a Diesel 306 Hdi must as soon as possible be drained out seeing as your likelihood of succeeding with that level of contamination is probably below one in 50 - really long odds.
  2. Put some Petrol in a Diesel Peugeot and drove it: Have you seen any kind of performance difficulties ever since putting the bad fuel in your 306 Hdi? If so, have it drained irrespective of the quantity of Petrol or the contamination percentage. Still running a motor vehicle that is already starting to suffer from the effects of wrong fuel contamination can typically result in increasing amounts of harm being done to your fuel system.
  3. Do you need security?
    Then get it emptied. No matter the contamination percentage, there is inevitably a certain level of risk affiliated with operating a Diesel vehicle on Diesel contaminated with the wrong fuel. Probable outcomes of driving on the incorrect fuel can include the motor refusing to start, running lumpy, decrease in power, degradation of the high-pressure pump, worn out or clogged injectors, etc. These are several of the most typical Petrol in Diesel warning signs, and if you recognise any of them then stop and get it removed as soon as possible.

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.
