Volkswagen Fuel Drain


Filling Petrol in a Diesel Volkswagen is a regularly occurring mistake to make. And what you want to do about it is dependent upon a number of factors. If you would like to know what you should do about this then stay with me.
Listed below are the main variables to take into account whenever determining whether or not to have a fuel drain:

  1. Exactly how much Petrol did you put in the Volkswagen, keeping in mind that the fuel tank capacity of the Volkswagen Polo TDI is most likely approximately 45 litres?
    1. A small quantity of Petrol, less than 2.25 litres of Petrol in a Diesel Polo TDI will in most cases not really be a massive problem. Experience has taught us that quantities under 2.25 litres (which is about 5% of the total fuel tank) is oftentimes able to be adequately diluted simply by thoroughly filling the tank with Diesel.
      It is rather unusual to encounter a car suffering from issues with below 5% wrong fuel contamination. Keep in mind that it's unusual - in no way impossible to find. You will discover a few cars that won't stand any level of contamination whatsoever.
    2. Somewhere between 2.25 and 4.5 litres of Petrol in the Volkswagen (5 to 10%) is a 50/50 condition. Our practical experience has demonstrated that as many drivers get away with it as all those who don't. When you are figuring out whether or not to chance it and simply top it up recognise that it is the same thing as wagering it all on black - you have a 50/50 chance of it being ok.
    3. Anything in excess of 4.5 litres of Petrol in your Diesel Polo TDI really should immediately be drained since your likelihood of succeeding with this quantity of contamination is undoubtedly less than one in 50 - genuinely big odds.
  2. Put Petrol in a Diesel Volkswagen and drove it: Have you noticed any performance difficulties as a result of putting the wrong fuel in your Polo TDI? If you have, have it drained no matter the amount of Petrol or even the contamination ratio. Proceeding to run running a motor vehicle that is currently beginning to suffer from the effect of fuel contamination will just lead to more and more harm affecting the fuel system parts.
  3. Do you want reassurance?
    Simply get it drained. Regardless of contamination ratio, there is inevitably a certain level of threat resulting from driving a Diesel engine on Diesel contaminated with Petrol. Likely outcomes of driving a car on the incorrect fuel can include the motor refusing to start, running lumpy, lack of power, degradation of the high-pressure pump, worn out or bunged injectors, and the like. These are some of the most typical Petrol in Diesel signs and symptoms, and should you recognise any of them then stop and have it removed right away.

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.
