Volkswagen Fuel Drain


Filling Petrol in a Diesel Volkswagen is a well-known mistake. And exactly what you want to do about it depends on several different things. Assuming you would like to know what you have to do to sort it out then keep reading.
Listed below are the key variables to take into consideration when deciding whether or not to get it drained:

  1. Exactly how much Petrol did you put into the Volkswagen, bearing in mind that the fuel tank capacity of your Volkswagen Multivan TDI is in most cases about 80 litres?
    1. A modest amount of Petrol, less than 4 litres of Petrol in a Diesel Multivan TDI will usually not be a significant problem. Experience has shown us that quantities under 4 litres (which is close to 5% of the entire fuel tank capacity) is sometimes able to be adequately diluted through totally filling the remainder of the tank with Diesel.
      It is very uncommon to come across a motor vehicle going through problems with below 5% incorrect fuel contamination. Keep in mind that it's rare - definitely not impossible to find. There are a few vehicles that won't stand any degree of contamination in the slightest.
    2. Between 4 and 8 litres of Petrol in the Volkswagen (5 to 10%) is more of a 50/50 scenario. Our practical experience demonstrates that as many motorists get away with this as all those who break down. Whenever you are deciding on whether to risk it and just simply fill it up recognise that it is just like wagering everything on black - you've got a 50/50 possibility of it working out.
    3. Anything more than 8 litres of Petrol in your Diesel Multivan TDI should as soon as possible be removed seeing as your probability of getting away with that quantity of contamination is undoubtedly less than one in 50 - definitely long odds.
  2. Put Petrol in a Diesel Volkswagen and drove it: Have you seen any kind of performance concerns ever since putting the incorrect fuel in your Multivan TDI? If so, have it emptied regardless of the amount of Petrol or even the contamination ratio. Proceeding to run driving a vehicle that is starting to suffer from the effects of fuel contamination can only cause more damage being done to your fuel system.
  3. Do you need assurance?
    Then simply just get it drained. Whatever the contamination ratio, there is inevitably some amount of danger resulting from operating a Diesel engine on fuel contaminated with the wrong fuel. Possible results of driving on the wrong fuel include the engine not starting, running unevenly, losing power, degradation of the high-pressure pump, worn or blocked injectors, and so forth. These are a few of the most common Petrol in Diesel symptoms, and in the event that you observe any of them then stop driving and have it drained right now.

Petrol in Diesel Questions

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.
