Volkswagen Fuel Drain


Filling up with Diesel in a Petrol Volkswagen is a common mistake. And its remedy will depend on a number of things. Assuming you want to find out what you have to do about it then keep on reading.
Here are the most crucial factors to be aware of when choosing whether or not to get your car drained:

  1. Exactly how much Diesel did you put into the Volkswagen, taking into consideration that the fuel capacity of your Volkswagen Beetle TSI is most likely about 55 litres?
    1. A tiny amount of Diesel, something like 2.75 litres of Diesel in a Petrol Beetle TSI will most of the time not necessarily be a major problem. Experience has proven to us that an amount less than 2.75 litres (almost 5% of the overall fuel tank) is very often able to be completely diluted simply by completely filling up the tank with Petrol.
      It is pretty rare to come across a motor vehicle experiencing problems with below 5% wrong fuel contamination. Remember that it is rare - in no way impossible to encounter. There are actually some motor vehicles that won't endure any degree of contamination in the slightest.
    2. Somewhere between 2.75 and 5.5 litres of Diesel in the Volkswagen (5 to 10%) is a 50/50 condition. Our working experience has shown us that as many drivers get away with it as all those who break down. Any time you are figuring out whether or not to chance it and just fill it up bear in mind that it is the same as betting your car on black - you have a 50/50 chance of it working out.
    3. Anything over 5.5 litres of Diesel in a Petrol Beetle TSI really should right away be drained seeing that your likelihood of driving with this amount of contamination is more than likely lower than one in fifty - truly huge odds.
  2. Put Diesel in a Petrol Volkswagen and drove it: Have you detected any kind of performance concerns as a result of putting the bad fuel in the Beetle TSI? If that's the case, have it removed no matter the volume of Diesel or even the contamination ratio. Still running a car that is beginning to suffer from the effects of fuel contamination will probably definitely lead to even more harm affecting the fuel system.
  3. Do you need assurance?
    Then get it drained. Regardless of the contamination percentage, there is inevitably some degree of risk connected with running a Petrol engine on Petrol contaminated with Diesel. Possible consequences of driving a vehicle on the incorrect fuel include the motor not starting, running unevenly, loss of power, wearing of the high-pressure pump, damaged or clogged injectors, etc. These are a few of the commonest Diesel in Petrol signs and symptoms, and in the event that you notice any of them stop and have it removed as soon as possible.

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.
