Volkswagen Fuel Drain


Putting Petrol in a Diesel Volkswagen is a usual mistake to make. And its solution will depend on a variety of factors. If you want to know what to do to sort it out then stay with me.
These are the key factors to to consider whenever deciding on whether or not to get your car drained:

  1. What amount of Petrol have you put in the Volkswagen, considering that the fuel tank capacity of your Volkswagen Fox TDI is in most cases about 50 litres?
    1. Hardly any Petrol, less than 2.5 litres of Petrol in a Diesel Fox TDI will in most situations not really be a huge problem. Experience has demonstrated to us that an amount less than 2.5 litres (which is approximately 5% of the fuel tank volume) is sometimes capable of being adequately diluted through completely filling the remainder of the tank with the right fuel.
      It is relatively uncommon to encounter a car or truck having difficulties due to under 5% incorrect fuel contamination. Keep in mind that it is very unusual - not impossible to find. You can get a number of cars that will not endure any amount of contamination at all.
    2. Anywhere between 2.5 and 5 litres of Petrol in the Volkswagen (5 to 10%) is more of a 50/50 situation. Our working experience demonstrates that as many drivers get away with this as those who don't. Any time you are deciding on whether or not to risk it and just top it up consider that it is much like betting it all on black - you have a 50/50 possibility of it working out.
    3. Anything in excess of 5 litres of Petrol in a Diesel Fox TDI ought to immediately be drained since your likelihood of succeeding with that quantity of contamination is more than likely below one in 50 - seriously big odds.
  2. Put Petrol in a Diesel Volkswagen and drove it: Have you seen any kind of performance troubles since putting the bad fuel in your Fox TDI? If so, get it removed no matter the quantity of Petrol or even the contamination ratio. Proceeding to run running a vehicle that is starting to suffer the effects of fuel contamination will typically end up in more and more harm being caused to the fuel system parts.
  3. Are you interested in reassurance?
    In that case get it drained. Regardless of the contamination percentage, there is inevitably some amount of danger connected to operating a Diesel motor on fuel contaminated with Petrol. Probable implications of driving on the incorrect fuel include things like the motor not starting, running unevenly, decrease in power, degradation of the high-pressure pump, worn out or clogged injectors, and so forth. These are a few of the most frequently seen Petrol in Diesel symptoms, and in the event that you recognise any of them then stop driving and get 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.
