Volkswagen Fuel Drain


Filling Diesel in a Petrol Volkswagen is a regularly occurring problem. And exactly what you should do about it depends upon an assortment of things. If you would like to find out what you need to do about this then keep reading.
Listed below are the main variables to consider when determining whether to have it drained:

  1. What amount of Diesel have you put in to the Volkswagen, bearing in mind that the fuel capacity of your Volkswagen Golf TSI is in most cases roughly 55 litres?
    1. Hardly any Diesel, something like 2.75 litres of Diesel in a Petrol Golf TSI will generally not necessarily be a massive problem. Experience has taught us that an amount under 2.75 litres (5% of the whole fuel tank) is oftentimes capable of being adequately diluted through entirely topping the rest of the tank with Petrol.
      It is highly unusual to find a car going through issues with below 5% incorrect fuel contamination. Please remember it's unusual - in no way impossible to encounter. You will discover some cars that don't endure any quantity of contamination whatsoever.
    2. Anywhere between 2.75 and 5.5 litres of Diesel in the Volkswagen (5 to 10%) is a 50/50 condition. Our experience has confirmed that as many motorists get away with it as all those who break down. When figuring out whether to risk it and simply top it up consider that it is the same thing as betting your car on black - you have got a 50/50 possibility of it being ok.
    3. Anything more than 5.5 litres of Diesel in a Petrol Golf TSI should really immediately be removed because your likelihood of getting away with this amount of contamination is almost certainly lower than one in fifty - extremely big odds.
  2. Put Diesel in a Petrol Volkswagen and drove it: Have you detected any performance concerns as a result of putting the bad fuel in the Golf TSI? If you have, get it emptied irrespective of the amount of Diesel or even the contamination ratio. Continuing to run driving a motor vehicle that is currently beginning to suffer the consequences of fuel contamination will probably typically lead to more harm affecting your fuel system components.
  3. Are you looking for assurance?
    In that case get it removed. Whatever the contamination percentage, there is invariably some amount of risk associated with running a Petrol engine on fuel contaminated with the incorrect fuel. Possible implications of driving on the wrong fuel can include the motor not starting, running unevenly, loss of power, wearing of the high-pressure pump, worn or bunged injectors, and so forth. These are a few of the commonest Diesel in Petrol signs or symptoms, and in the event that you observe any of them stop and get it removed immediately.

Diesel in Petrol Questions

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.
