Peugeot Fuel Drain


Filling Diesel in a Petrol Peugeot is a very common mistake to make. And what you want to do about it varies according to an assortment of factors. If you want to know what it is best to do to sort it out then continue reading.
These are the most important factors to to consider whenever deciding whether or not to have a fuel drain:

  1. Exactly how much Diesel did you put in to the Peugeot, taking into account that the fuel tank capacity of your Peugeot 406 is usually roughly 70 litres?
    1. A small quantity of Diesel, as little as 3.5 litres of Diesel in a Petrol 406 will usually not really be a huge problem. Experience has shown us that quantities less than 3.5 litres (close to 5% of the total fuel tank) is often capable of being adequately diluted simply by completely topping up the remainder of the tank with Petrol.
      It is pretty uncommon to find a car or truck having issues because of lower than 5% wrong fuel contamination. Please remember it is very infrequent - in no way impossible to encounter. You will discover a few automobiles that won't endure any level of contamination whatsoever.
    2. Between 3.5 and 7 litres of Diesel in the Peugeot (from 5 to 10%) is really a 50/50 scenario. Our working experience has demonstrated that as many people get away with this as all those who don't. When you are deciding whether or not to risk it and simply top it up remember that it is the same thing as betting all of it on black - you will have a 50/50 chance of it working.
    3. Anything above 7 litres of Diesel in your Petrol 406 really should promptly be drained seeing as your probability of getting away with that quantity of contamination is almost certainly lower than one in 50 - extremely huge odds.
  2. Put Diesel in a Petrol Peugeot and drove it: Have you observed any performance concerns after putting the bad fuel in the 406? If so, have it emptied irrespective of the amount of Diesel or the contamination percentage. Continually running a vehicle that is starting to suffer from the consequences of wrong fuel contamination will typically bring about increasing amounts of damage affecting your fuel system parts.
  3. Are you interested in reassurance?
    Simply get it removed. Regardless of the contamination ratio, there is inevitably some degree of risk resulting from operating a Petrol motor on fuel contaminated with the incorrect fuel. Possible outcomes of driving on the wrong fuel normally include the engine not starting, running unevenly, losing power, wearing of the high-pressure pump, worn or bunged injectors, etc. These are several of the most common Diesel in Petrol signs or symptoms, and if you observe any of them stop and have it removed immediately.

Diesel in Petrol FAQs

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.
