Volkswagen Fuel Drain


Putting Petrol in a Diesel Volkswagen is a very common error. And its remedy is based on various things. If you would like to find out what you have to do about this then keep reading.
Listed below are the key factors to keep in mind whenever deciding on whether to have a fuel drain:

  1. How much Petrol have you put into the Volkswagen, taking into account that the fuel tank capacity of your Volkswagen CrossGolf TDI is most likely around 55 litres?
    1. A modest amount of Petrol, something like 2.75 litres of Petrol in a Diesel CrossGolf TDI will usually not be a massive problem. Experience has shown us that anything under 2.75 litres (which is about 5% of the entire fuel tank) is oftentimes able to be adequately diluted by totally filling up the remainder of the tank with Diesel.
      It's extremely uncommon to find an automobile going through problems due to less than 5% incorrect fuel contamination. Bear in mind that it's rare - certainly not impossible to encounter. There are a few vehicles that don't stand any level of contamination in the slightest.
    2. Somewhere between 2.75 and 5.5 litres of Petrol in the Volkswagen (from 5 to 10%) is a 50/50 condition. Our expertise has shown that as many motorists get away with this as all those who don't. Whenever figuring out whether or not to risk it and just fill it up remember that it is just like betting everything on black - you will have a 50/50 possibility of it being ok.
    3. Anything over 5.5 litres of Petrol in your Diesel CrossGolf TDI should straight away be drained seeing that your probability of driving with this amount of contamination is undoubtedly less than one in fifty - truly big odds.
  2. Put Petrol in a Diesel Volkswagen and drove it: Have you observed any kind of performance problems ever since putting the wrong fuel in the CrossGolf TDI? If that's the case, get it removed irrespective of the volume of Petrol or the contamination ratio. Continuing to run driving an automobile that is already starting to suffer the consequences of wrong fuel contamination will probably definitely end up in increasing amounts of damage being caused to your fuel system.
  3. Do you need reassurance?
    In that case get it emptied. Whatever the contamination percentage, there is invariably some extent of danger resulting from driving a Diesel motor on fuel contaminated with Petrol. Probable outcomes of driving on the wrong fuel can include the motor not starting, running unevenly, loss of power, wearing of the high-pressure pump, damaged or blocked injectors, and so on. These are a few of the commonest Petrol in Diesel signs or symptoms, and should you notice any of them then stop and have it removed immediately.

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.
