Volkswagen Fuel Drain


Putting Petrol in a Diesel Volkswagen is a well-known mistake to make. And exactly what you have to do about it is dependent upon several things. In the event that you would like to find out what it is best to do about it then please read on.
Listed here are the most crucial variables to take into consideration when choosing whether or not to have the car drained:

  1. What level of Petrol have you put into the Volkswagen, keeping in mind that the fuel capacity of your Volkswagen Phaeton TDI is probably about 90 litres?
    1. A modest amount of Petrol, something like 4.5 litres of Petrol in a Diesel Phaeton TDI will quite often not be a major problem. Experience has shown us that anything less than 4.5 litres (which is close to 5% of the fuel tank volume) is oftentimes capable of being completely diluted through entirely topping up the rest of the tank with Diesel.
      It is quite rare to encounter an automobile having issues because of below 5% wrong fuel contamination. Keep in mind that it is very rare - definitely not impossible to encounter. There are a number of vehicles that won't endure any quantity of fuel contamination at all.
    2. Somewhere between 4.5 and 9 litres of Petrol in the Volkswagen (from 5 to 10%) is a 50/50 condition. Our working experience has demonstrated that as many motorists get away with it as those who break down. Whenever you are deciding on whether or not to chance it and just fill it up recognise that it is much like gambling it all on black - you have got a 50/50 chance of it being ok.
    3. Anything more than 9 litres of Petrol in a Diesel Phaeton TDI ought to straightaway be drained out since your probability of driving with this level of contamination is probably less than one in 50 - seriously huge odds.
  2. Put Petrol in a Diesel Volkswagen and drove it: Have you noted any kind of performance concerns since putting the incorrect fuel in the Phaeton TDI? If you have, have it drained irrespective of the volume of Petrol or the contamination ratio. Still running an automobile that is currently starting to suffer the effects of wrong fuel contamination can just cause increasing amounts of harm being done to your fuel system parts.
  3. Do you want assurance?
    Then simply just get it emptied. Regardless of contamination percentage, there is always some amount of risk linked with running a Diesel motor on fuel contaminated with Petrol. Possible implications of driving on the incorrect fuel include the engine refusing to start, running lumpy, lack of power, degradation of the high-pressure pump, worn or bunged injectors, and so on. These are some of the most typical Petrol in Diesel signs and symptoms, and if you notice any of them then stop and get it removed right now.

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.
