Volkswagen Fuel Drain


Putting Petrol in a Diesel Volkswagen is a well-known error. And exactly what you should do about it is dependent upon a number of factors. In case you want to find out what to do about this then keep on reading.
Right here are the key factors to take into consideration whenever choosing whether to have a fuel drain:

  1. What amount of Petrol did you put into the Volkswagen, bearing in mind that the fuel capacity of your Volkswagen Passat CC TDI is most likely roughly 70 litres?
    1. A small amount of Petrol, something like 3.5 litres of Petrol in a Diesel Passat CC TDI will most of the time not necessarily be a massive problem. Experience has demonstrated to us that anything under 3.5 litres (which is almost 5% of the total fuel tank volume) is frequently able to be adequately diluted through thoroughly topping up the remainder of the tank with the right fuel.
      It is rather uncommon to find a motor vehicle going through difficulties due to below 5% wrong fuel contamination. Keep in mind it is very uncommon - not impossible to encounter. There are certain cars that won't endure any level of contamination at all.
    2. Between 3.5 and 7 litres of Petrol in the Volkswagen (5 to 10%) is really a 50/50 scenario. Our practical experience has revealed that as many people get away with it as those people who don't. Whenever you are figuring out whether or not to chance it and basically top it up consider that it is just like wagering all of it on black - you have a 50/50 possibility of it being ok.
    3. Anything in excess of 7 litres of Petrol in your Diesel Passat CC TDI ought to right away be drained since your likelihood of succeeding with this amount of contamination is in all likelihood lower than one in fifty - really huge odds.
  2. Put some Petrol in a Diesel Volkswagen and drove it: Have you noticed any kind of performance issues ever since putting the wrong fuel in the Passat CC TDI? If you have, have it emptied irrespective of the volume of Petrol or the contamination ratio. Continually driving a vehicle that is now beginning to suffer from the consequences of fuel contamination will definitely bring about more and more harm being caused to your fuel system.
  3. Are you looking for reassurance?
    Then get it removed. Regardless of the contamination percentage, there is invariably some amount of risk linked with operating a Diesel motor on fuel contaminated with Petrol. Likely final outcomes of driving on the incorrect fuel include the motor refusing to start, running lumpy, losing power, degradation of the high-pressure pump, damaged or bunged injectors, and so forth. These are some of the most typical Petrol in Diesel symptoms, and in the event that you observe any of them 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.
